V-belt and flat “polyvee” type
drivebelt with rack-and-pinion type
adjuster
12Loosen off the alternator mounting bolts
and the adjusting arm mounting bolt. Slacken
the pinion central locking bolt, and turn the
pinion nut as required to take up the tension
of the drivebelt. Hold it at the required setting,
and tighten the central bolt securely to lock
the adjuster arm and set the tension (see
illustrations) .
13 Tighten the alternator mounting and
adjusting arm bolts securely.
14 Refit the auxiliary drivebelt cover (where
applicable) and roadwheel, then lower the
vehicle to the ground.
15 Run the engine for about five minutes,
then recheck the tension.
Flat “polyvee” type drivebelt with
tensioner pulley adjuster (HCS engine
power steering pump drivebelt)
16 Slacken the tensioner pulley centre bolt
then turn the adjuster bolt at the base of the
tensioner pulley bracket, as required, to take
up the tension of the drivebelt. When the belt
deflection is correct, tighten the adjuster
pulley centre retaining bolt.
17 Refit the auxiliary drivebelt cover (where
applicable) and roadwheel, then lower the
vehicle to the ground.
18 Run the engine for about five minutes,
then recheck the tension.
Flat “polyvee” type drivebelt with
automatic adjuster
19 As mentioned above, this type of drivebelt
is tensioned by an automatic tensioner;
regular checks are not required, and manual
“adjustment” is not possible.
20 If you suspect that the drivebelt is slipping
and/or running slack, or that the tensioner is
otherwise faulty, it must be renewed. To do
this, remove the drivebelt as described below,
then unbolt and remove the tensioner. On
fitting the new tensioner, ensure that it is
aligned correctly on its mountings, and
tightened to the specified torque wrench
setting.
Renewal
21 Open the bonnet. Jack up the front right-
hand side of the vehicle, and support it
securely on an axle stand. Remove the
roadwheel, then remove the auxiliary drivebelt
lower cover (where fitted) from inside the
wheel arch.
22 The routing of the drivebelt around the
pulleys is dependent on the drivebelt type,
and on whether power steering is fitted.
Before removing the drivebelt, it’s a good idea
to sketch the belt run around the pulleys; this
will save a lot of frustration when it comes to
refitting. Note that on HCS engines with
power steering, to renew the alternator/
water pump drivebelt it will be necessary to
remove the power steering pump drivebelt
first.
23 If the existing drivebelt is to be refitted,
mark it, or note the maker’s markings on its
flat surface, so that it can be installed the
same way round.
24 To renew a drivebelt with manual
adjustment, slacken the belt tension fully as
described above, according to type. Slip the
belt off the pulleys, then fit the new belt,
ensuring that it is routed correctly. If fitting a
flat “polyvee” type drivebelt, arrange it on the
grooved pulleys so that it is centred in
their grooves, and not overlapping their raised
sides. With the belt in position, adjust the
tension as previously described.
25 To renew the flat, “polyvee” type drivebelt
with automatic adjuster, reach up between
the body and the engine (above the
crankshaft pulley), and apply a spanner to the
hexagon in the centre of the automatic
tensioner’s pulley. Rotate the tensioner pulley
clockwise to release its pressure on the
drivebelt, then slip the drivebelt off the
crankshaft pulley, and release the tensioner
again (see illustration) . Note that on certain
models, a self-cocking tensioner is fitted, and
that this will remain in the released position.
Working from the wheel arch or engine
compartment as necessary, and noting its
routing, slip the drivebelt off the remaining
pulleys and withdraw it.
26 Check all the pulleys, ensuring that their
grooves are clean, and removing all traces of oil and grease. Check that the tensioner
works properly, with strong spring pressure
being felt when its pulley is rotated clockwise,
and a smooth return to the limit of its travel
when released.
27
If the original drivebelt is being refitted,
use the marks or notes made on removal, to
ensure that it is installed to run in the same
direction as it was previously. To fit the
drivebelt, arrange it on the grooved pulleys so
that it is centred in their grooves, and not
overlapping their raised sides, and is routed
correctly. Start at the top, and work down to
finish at the crankshaft pulley; rotate the
tensioner pulley clockwise, slip the drivebelt
onto the crankshaft pulley, then release the
tensioner again.
28 Using a spanner applied to the crankshaft
pulley bolt, rotate the crankshaft through at
least two full turns clockwise to settle the
drivebelt on the pulleys, then check that
the drivebelt is properly installed.
29 Refit the auxiliary drivebelt cover (where
applicable) and roadwheel, then lower the
vehicle to the ground.
5 Underbonnet check for fluid leaks and hose condition
1
General
1High temperatures in the engine
compartment can cause the deterioration of
the rubber and plastic hoses used for engine,
accessory and emissions systems operation.
Periodic inspection should be made for
cracks, loose clamps, material hardening and
leaks.
2 Carefully check the large top and bottom
radiator hoses, along with the other smaller-
diameter cooling system hoses and metal
pipes; do not forget the heater hoses/pipes
which run from the engine to the bulkhead.
Inspect each hose along its entire length,
replacing any that is cracked, swollen or
shows signs of deterioration. Cracks may
become more apparent if the hose is

squeezed (see illustration) . If you are using
non-Ford specification antifreeze, and so
have to renew the coolant every two years or
so, it’s a good idea to renew the hoses at that
time, regardless of their apparent condition.
3 Make sure that all hose connections are
tight. A leak in the cooling system will usually
show up as white- or rust-coloured deposits
on the areas adjoining the leak; if the spring
clamps that are used to secure the hoses in
this system appear to be slackening, they
should be renewed to prevent the possibility
of leaks.
4 Some other hoses are secured to their
fittings with clamps. Where clamps are used,
check to be sure they haven’t lost their
tension, allowing the hose to leak. If clamps
aren’t used, make sure the hose has not
expanded and/or hardened where it slips over
the fitting, allowing it to leak.
5 Check all fluid reservoirs, filler caps, drain
plugs and fittings etc, looking for any signs
of leakage of oil, transmission and/or brake
hydraulic fluid, coolant and power steering
fluid. If the vehicle is regularly parked in the
same place, close inspection of the ground
underneath it will soon show any leaks. As
soon as a leak is detected, its source must
be traced and rectified. Where oil has been
leaking for some time, it is usually necessary
to use a steam cleaner, pressure washer or
similar, to clean away the accumulated
dirt, so that (when the engine is run again)
the exact source of the leak can be
identified.
Vacuum hoses
6 It’s quite common for vacuum hoses,
especially those in the emissions system, to be
colour-coded, or to be identified by coloured stripes moulded into them. Various systems
require hoses with different wall thicknesses,
collapse resistance and temperature
resistance. When renewing hoses, be sure the
new ones are made of the same material.
7
Often the only effective way to check a
hose is to remove it completely from the
vehicle. If more than one hose is removed, be
sure to label the hoses and fittings to ensure
correct installation.
8 When checking vacuum hoses, be sure to
include any plastic T-fittings in the check.
Inspect the fittings for cracks, and check the
hose where it fits over the fitting for distortion,
which could cause leakage.
9 A small piece of vacuum hose (quarter-inch
inside diameter) can be used as a
stethoscope to detect vacuum leaks. Hold
one end of the hose to your ear, and probe
around vacuum hoses and fittings, listening
for the “hissing” sound characteristic of a
vacuum leak. Warning: When probing with the
vacuum-hose stethoscope, be
very careful not to come into
contact with moving engine
components such as the auxiliary
drivebelt, radiator electric cooling fan, etc.
Fuel hoses
Warning: There are certain
precautions which must be
taken when inspecting or
servicing fuel system
components. Work in a well-ventilated
area, and do not allow open flames
(cigarettes, appliance pilot lights, etc.) or
bare light bulbs near the work area. Mop
up any spills immediately, and do not store
fuel-soaked rags where they could ignite.
10 Check all fuel hoses for deterioration and
chafing. Check especially for cracks in areas
where the hose bends, and also just before
fittings, such as where a hose attaches to the
fuel filter.
11 High-quality fuel line, usually identified by
the word “Fluoroelastomer” printed on the
hose, should be used for fuel line renewal.
Never, under any circumstances, use
unreinforced vacuum line, clear plastic tubing
or water hose for fuel lines.
12 Spring- type clamps are commonly used
on fuel lines. These clamps often lose their
tension over a period of time, and can be
“sprung” during removal. Replace all
spring- type clamps with screw clamps
whenever a hose is replaced.
Metal lines
13 Sections of metal piping are often used
for fuel line between the fuel filter and the
engine. Check carefully to be sure the piping
has not been bent or crimped, and that cracks
have not started in the line.
14 If a section of metal fuel line must be
renewed, only seamless steel piping should
be used, since copper and aluminium piping
don’t have the strength necessary to
withstand normal engine vibration. 15
Check the metal brake lines where they
enter the master cylinder and ABS hydraulic
unit (if used) for cracks in the lines or loose
fittings. Any sign of brake fluid leakage calls
for an immediate and thorough inspection of
the brake system.
6 Engine compartment wiring check
1
1With the vehicle parked on level ground,
apply the handbrake firmly and open the
bonnet. Using an inspection light or a small
electric torch, check all visible wiring within
and beneath the engine compartment.
2 What you are looking for is wiring that is
obviously damaged by chafing against sharp
edges, or against moving suspension/
transmission components and/or the auxiliary
drivebelt, by being trapped or crushed
between carelessly-refitted components, or
melted by being forced into contact with the
hot engine castings, coolant pipes, etc. In
almost all cases, damage of this sort is
caused in the first instance by incorrect
routing on reassembly, after previous work
has been carried out.
3 Depending on the extent of the problem,
damaged wiring may be repaired by rejoining
the break or splicing-in a new length of wire,
using solder to ensure a good connection,
and remaking the insulation with adhesive
insulating tape or heat-shrink tubing, as
appropriate. If the damage is extensive, given
the implications for the vehicle’s future
reliability, the best long-term answer may well
be to renew that entire section of the loom,
however expensive this may appear.
4 When the actual damage has been
repaired, ensure that the wiring loom is re-
routed correctly, so that it is clear of other
components, and not stretched or kinked, and
is secured out of harm’s way using the plastic
clips, guides and ties provided.
5 Check all electrical connectors, ensuring
that they are clean, securely fastened, and
that each is locked by its plastic tabs or wire
clip, as appropriate. If any connector shows
external signs of corrosion (accumulations of
white or green deposits, or streaks of “rust”),
or if any is thought to be dirty, it must be
unplugged and cleaned using electrical
contact cleaner. If the connector pins are
severely corroded, the connector must be
renewed; note that this may mean the renewal
of that entire section of the loom - see your
local Ford dealer for details.
6 If the cleaner completely removes the
corrosion to leave the connector in a
satisfactory condition, it would be wise to
pack the connector with a suitable material
which will exclude dirt and moisture,
preventing the corrosion from occurring
again; a Ford dealer may be able to
recommend a suitable product.
7 Check the condition of the battery

connections - remake the connections or
renew the leads if a fault is found. Use the
same techniques to ensure that all earth
points in the engine compartment provide
good electrical contact through clean, metal-
to-metal joints, and that all are securely
fastened. (In addition to the earth connection
at the engine lifting eye, and that from the
transmission to the body/battery, there are
others in various places, so check carefully).
8Refer to Section 21 for details of spark plug
(HT) lead checks.

Refer to Chapter 2, Part A.
8 Manual transmission oil level check
1
1The manual transmission does not have a
dipstick. To check the oil level, raise the
vehicle and support it securely on axle stands,
making sure that the vehicle is level. On the
lower front side of the transmission housing,
you will see the filler/level plug. Unscrew and
remove it - an Allen key or bit will probably be
required (see illustration) .
2 With the plug removed, check the oil level.
To do this accurately, make up an oil level
check dipstick from a short length of welding
rod or similar material. Make a 90º bend in the
rod, then mark the downward leg in 5 mm
increments. The dipstick is then inserted
through the filler plug orifice so that the
unmarked leg rests flat on the plug orifice
threads, with the marked leg dipped in the oil.
Withdraw the dipstick and read off the level of
oil.
3 The oil level must be maintained between 0
and 5 mm below the lower edge of the
filler/level plug hole. Top up (if necessary),
using fresh transmission oil of the specified
type and using a syringe, or a plastic bottle
and tube. Refit and tighten the filler/level plug
to the specified torque on completion. 4
The need for regular topping-up can only
be due to a leak, which should be found and
rectified without delay.
5 Regular oil changing is not specified by the
manufacturer’s, but the oil can be drained, if
required, by removing the selector shaft cap
nut and locking assembly.
9 Idle speed and mixture check and adjustment
4
General
1Many of the engines fitted to Fiesta models
are equipped with fuel injection systems of
one sort or another which are entirely
controlled by the engine management system.
On most of these vehicles, it isn’t possible to
make any adjustments to the idle speed or the
mixture settings without specialist test
equipment of a type usually only found at a
Ford dealer or fuel injection specialist.
However, the very nature of these highly-
sophisticated systems means they don’t go
out of tune very often (if ever), so that it’s one
less maintenance operation to worry about.
2 On carburettor engines and 1.6 litre EFi fuel
injection engines, certain checks and
adjustments are necessary as part of the
service requirements, and these are described
below.
Idle speed and mixture check
and adjustment - carburettor
engines
Note: Later carburettors are fitted with
tamperproof mixture adjusting screws,
consisting of a hexagon-shaped socket with a
pin in the centre. Such screws require the use
of Ford service tool 23-032 to alter their
settings; if this tool (or a suitable equivalent) is
not available, the CO level will have to be
checked, and any necessary adjustment will
have to be made, by a Ford dealer.
3 Before carrying out the following checks
and adjustments, ensure that the spark plugs
are in good condition and correctly gapped
(Section 21). To carry out the checks/adjustments, an accurate tachometer
and an exhaust gas analyser (CO meter) will
be required.
4
Make sure that all electrical components
are switched off during the following
procedures.
5 Connect a tachometer to the engine in
accordance with its manufacturer’s
instructions, and insert the probe of an
exhaust gas analyser (CO meter) into the
exhaust tailpipe. As previously mentioned,
these items are essential in obtaining an
accurate setting. If they are not available, an
approximate check/adjustment can be made
as a temporary measure, providing they are
further checked out as soon as is possible
using a tachometer and a CO meter (or by a
Ford dealer).
6 Run the engine at a fast idle speed until it
reaches its normal operating temperature and
the radiator cooling fan cuts in. Turn the
engine off, then disconnect the radiator
cooling fan lead at the thermostatic switch
connector. Now connect a temporary wire to
the fan switch multi-plug, as shown (see
illustration) to enable the fan to operate
continuously during the following checks and
adjustments (if this is specified). Take care to
keep clear of the fan during the following
operations when working in the engine
compartment.
7 Where fitted, disconnect the throttle kicker
vacuum pipe, and plug the end. To identify
the throttle kicker unit, refer to Chapter 4A.
8 Check that the vehicle lighting and other
electrical loadings (apart from the radiator
cooling fan) are switched off, then restart the
engine. Increase the engine speed to 3000 rpm
for 30 seconds, and repeat this at three-minute
intervals during the check/adjustment
procedures. This will ensure that any excess
fuel is cleared from the inlet manifold.
9 Ensure that the throttle is fully released, allow
the meters to stabilise for a period of 5 to
30 seconds is normally sufficient, then check
the idle speed against that specified. If adjust-
ment is necessary, turn the idle speed
adjusting screw until the engine is idling at the
specified speed (see illustrations) . Any checks
and adjustments must be completed within
30 seconds of the meters stabilising.

10If adjustment to the mixture is required,
the tamperproof cap will need to be removed
from the carburettor to gain access to the
mixture screw. To do this, first unclip the fuel
trap from the side of the air cleaner unit, then
remove the air cleaner unit, ensuring that the
crankcase ventilation trap remains connected.
Prise free the tamperproof cap (with the aid of
a thin-bladed screwdriver), then with the
vacuum and emissions control pipes
connected to it, relocate the air cleaner unit
temporarily into position.
11 Turn the mixture adjustment screw
clockwise to weaken the mixture, or
anti-clockwise to richen it, until the CO
reading is as given in the Specifications. If a
CO meter is not being used, weaken the
mixture as described, then enrich the mixture until the maximum engine speed is obtained,
consistent with even running.
12
If necessary, re-adjust the idle speed then
check the CO reading again. Repeat as
necessary until both the idle speed and CO
reading are correct.
13 Where required by law (as in some
European countries), fit a new tamperproof
cap to the mixture adjustment screw.
14 Disconnect the tachometer and the CO
meter, refit the air cleaner unit, and reconnect
the fan switch lead to complete.
Base idle speed and mixture
check and adjustment - 1.6 litre
EFi engines
15 Proceed as described above in
paragraphs 3 to 6 inclusive, then continue as
follows.
16 Run the engine at a fast idle speed until it
reaches its normal operating temperature and
the cooling fan cuts in. Check the CO content
of the exhaust, and compare it against the
specified reading. If the CO content reading is
incorrect, it can be adjusted by prising free
the tamperproof cap for access to the mixture
CO adjustment screw (see illustration), and
turning the screw in the required direction to
suit.
17 The operational idle speed is controlled by
the EEC IV engine management module and is
not adjustable. However, if the base idle
speed is incorrect, the module will not have an
accurate datum point from which to establish the normal operational idle speed. If idle
problems have been experienced, the base
idle speed should be checked as follows.
18
Disconnect the multi-plug from the idle
speed control valve and increase the engine
speed to 2000 rpm, hold it at that speed for
30 seconds, then fully release the throttle and
check if the base idle speed registered is as
specified.
19 If adjustment is necessary, prise free the
tamperproof plug using a suitable small
screwdriver to gain access to the base idle
speed adjustment screw in the throttle body.
Turn the screw in the required direction to
adjust the base idle speed to the specified
amount. Turning the screw anti-clockwise
increases the idle speed (see illustration).
20 Increase the engine speed to 2000 rpm
again, hold it at that speed for 30 seconds,
then fully release the throttle once more.
Check and further adjust the base idle speed
if required, then fit a new tamperproof plug
into position.
21 Reconnect the idle speed control valve
multi-plug and check that the engine speed
briefly rises to about 900 rpm, then drops
down to the specified normal idle speed.
22 On completion, disconnect the
tachometer and the CO meter, but continue
running the engine at idle speed for a period
of about five minutes, to enable the engine
management module to relearn its values
before switching it off.

lubricant, together with dirt and water entry,
resulting in rapid deterioration of the balljoints
or steering gear.
3Check the power-assisted steering fluid
hoses (where fitted) for chafing or
deterioration, and the pipe and hose unions
for fluid leaks. Also check for signs of fluid
leakage under pressure from the steering gear
rubber gaiters, which would indicate failed
fluid seals within the steering gear.
4 Grasp the roadwheel at the 12 o’clock and
6 o’clock positions, and try to rock it. Very
slight free play may be felt, but if the
movement is appreciable, further investigation
is necessary to determine the source.
Continue rocking the wheel while an assistant
depresses the footbrake. If the movement is
now eliminated or significantly reduced, it is
likely that the hub bearings are at fault. If the
free play is still evident with the footbrake
depressed, then there is wear in the
suspension joints or mountings.
5 Now grasp the wheel at the 9 o’clock and 3
o’clock positions, and try to rock it as before.
Any movement felt now may again be caused
by wear in the hub bearings or the steering
track rod balljoints. If the outer track rod end
balljoint is worn, the visual movement will be
obvious. If the inner joint is suspect, it can be
felt by placing a hand over the rack-and-
pinion rubber gaiter, and gripping the track
rod. If the wheel is now rocked, movement will
be felt at the inner joint if wear has taken
place.
6 Using a large screwdriver or flat bar, check
for wear in the suspension mounting bushes
by levering between the relevant suspension
component and its attachment point. Some
movement is to be expected, as the
mountings are made of rubber, but excessive
wear should be obvious. Also check the
condition of any visible rubber bushes,
looking for splits, cracks or contamination of
the rubber.
7 With the vehicle standing on its wheels,
have an assistant turn the steering wheel
back-and-forth, about an eighth of a turn each
way. There should be very little, if any, lost
movement between the steering wheel and
roadwheels. If this is not the case, closely
observe the joints and mountings previously described, but in addition, check the steering
column universal joints for wear, and also
check the rack-and-pinion steering gear itself.
Rear suspension check
8
Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the rear roadwheels.
9 Check the rear hub bearings for wear, using
the method described for the front hub
bearings (paragraph 4).
10 Using a large screwdriver or flat bar,
check for wear in the suspension mounting
bushes by levering between the relevant
suspension component and its attachment
point. Some movement is to be expected, as
the mountings are made of rubber, but
excessive wear should be obvious. Check the
condition of the shock absorbers and their
bushes/mountings. On Van models, check the
leaves of the leaf springs for signs of cracking,
distortion, or other damage.
Roadwheel check and balancing
11 Periodically remove the roadwheels, and
clean any dirt or mud from the inside and
outside surfaces. Examine the wheel rims for
signs of rusting, corrosion or other damage.
Light alloy wheels are easily damaged by
“kerbing” whilst parking, and similarly, steel
wheels may become dented or buckled.
Renewal of the wheel is very often the only
course of remedial action possible.
12 The balance of each wheel and tyre
assembly should be maintained, not only to
avoid excessive tyre wear, but also to avoid
wear in the steering and suspension
components. Wheel imbalance is normally
signified by vibration through the vehicle’s
bodyshell, although in many cases it is
particularly noticeable through the steering
wheel. Conversely, it should be noted that
wear or damage in suspension or steering
components may cause excessive tyre wear.
Out-of-round or out-of-true tyres, damaged
wheels and wheel bearing wear/
maladjustment also fall into this category.
Balancing will not usually cure vibration
caused by such wear.
13 Wheel balancing may be carried out with
the wheel either on or off the vehicle. If balanced on the vehicle, ensure that the
wheel-to-hub relationship is marked in some
way prior to subsequent wheel removal, so
that it may be refitted in its original position.
11 Driveshaft rubber gaiter and
CV joint check
1
1The driveshaft rubber gaiters are very
important, because they prevent dirt, water
and foreign material from entering and
damaging the constant velocity (CV) joints.
External contamination can cause the gaiter
material to deteriorate prematurely, so it’s a
good idea to wash the gaiters with soap and
water occasionally.
2 With the vehicle raised and securely
supported on axle stands, turn the steering
onto full-lock, then slowly rotate each front
wheel in turn. Inspect the condition of the
outer constant velocity (CV) joint rubber
gaiters, squeezing the gaiters to open out the
folds. Check for signs of cracking, splits, or
deterioration of the rubber, which may allow
the escape of grease, and lead to the ingress
of water and grit into the joint (see
illustration) . Also check the security and
condition of the retaining clips. Repeat these
checks on the inner CV joints. If any damage
or deterioration is found, the gaiters should be
renewed as described in Chapter 8.
3 At the same time, check the general
condition of the outer CV joints themselves,
by first holding the driveshaft and attempting
to rotate the wheels. Any appreciable
movement in the CV joint indicates wear in the
joint, wear in the driveshaft splines, or a loose
driveshaft retaining nut. Repeat this check on
the inner joints, by holding the inner joint yoke
and attempting to rotate the driveshaft.
12 Exhaust system check

point at the engine to the end of the tailpipe.
Ideally, this should be done on a hoist, where
unrestricted access is available; if a hoist is
not available, raise and support the vehicle on
axle stands.
2Check the pipes and connections for
evidence of leaks, severe corrosion, or
damage. Make sure that all brackets and
rubber mountings are in good condition, and
tight; if any of the mountings are to be
renewed, ensure that the replacements are of
the correct type (see illustration) . Leakage at
any of the joints or in other parts of the system
will usually show up as a black sooty stain in
the vicinity of the leak. Note: Exhaust sealants
should not be used on any part of the exhaust
system upstream of the catalytic converter -
even if the sealant does not contain additives
harmful to the converter, pieces of it may
break off and foul the element, causing local
overheating.
3 At the same time, inspect the underside of
the body for holes, corrosion, open seams,
etc, which may allow exhaust gases to enter
the passenger compartment. Seal all body
openings with silicone or body putty.
4 Rattles and other noises can often be
traced to the exhaust system, especially the
rubber mountings. Try to move the system,
silencer(s) and catalytic converter. If any
components can touch the body or
suspension parts, secure the exhaust system
with new mountings.
5 Check the running condition of the engine
by inspecting inside the end of the tailpipe;
the exhaust deposits here are an indication
of the engine’s state of tune. The inside of the
tailpipe should be dry, and should vary in
colour from dark grey to light grey/brown; if it
is black and sooty, or coated with white
deposits, the engine is in need of a thorough
fuel system inspection.
13 Underbody and fuel/brake line check
1
1With the vehicle raised and supported on
axle stands or over an inspection pit,
thoroughly inspect the underbody and wheel
arches for signs of damage and corrosion. In
particular, examine the bottom of the side
sills, and any concealed areas where mud can
collect. Where corrosion and rust is evident,
press and tap firmly on the panel with a
screwdriver, and check for any serious
corrosion which would necessitate repairs. If
the panel is not seriously corroded, clean
away the rust, and apply a new coating of
underseal. Refer to Chapter 11 for more
details of body repairs.
2 At the same time, inspect the PVC-coated
lower body panels for stone damage and
general condition.
3 Inspect all of the fuel and brake lines on the
underbody for damage, rust, corrosion and
leakage. Also make sure that they are correctly supported in their clips. Where
applicable, check the PVC coating on the
lines for damage.
14 Brake check
2
Note:
For detailed photographs of the brake
system, refer to Chapter 9.
1 The work described in this Section should
be carried out at the specified intervals, or
whenever a defect is suspected in the braking
system. Any of the following symptoms could
indicate a potential brake system defect:
a) The vehicle pulls to one side when the brake pedal is depressed.
b) The brakes make scraping or dragging
noises when applied.
c) Brake pedal travel is excessive.
d) The brake fluid requires repeated topping-
up.
2 A thorough inspection should be made to
confirm the thickness of the linings, as
follows.
Front brakes
3 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
4 For better access to the brake calipers,
remove the wheels.
5 Look through the inspection window in the
caliper, and check that the thickness of the
friction lining material on each of the pads is
not less than the recommended minimum
thickness given in the Specifications. Note:
Bear in mind that the lining material is normally
bonded to a metal backing plate.
6 If it is difficult to determine the exact
thickness of the pad linings, or if you are at all
concerned about the condition of the pads,
then remove them from the calipers for further
inspection (refer to Chapter 9).
7 Check the remaining brake caliper in the
same way.
8 If any one of the brake pads has worn down to, or below, the specified limit,
all fourpads
must be renewed as a set.
9 Measure the thickness of the discs with a
micrometer, if available, to make sure that they
still have service life remaining. If any disc is
thinner than the specified minimum thickness,
renew it (refer to Chapter 9). In any case,
check the general condition of the discs. Look
for excessive scoring and discolouration
caused by overheating. If these conditions
exist, remove the relevant disc and have it
resurfaced or renewed (refer to Chapter 9).
10 Before refitting the wheels and lowering
the car, check all brake lines and hoses (refer
to Chapter 9). In particular, check the flexible
hoses in the vicinity of the calipers, where
they are subjected to most movement. Bend
them between the fingers (but do not actually
bend them double, or the casing may be
damaged) and check that this does not reveal
previously-hidden cracks, cuts or splits.
Rear brakes
11 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
12 For better access, remove the rear
wheels.
13 To check the brake shoe lining thickness
without removing the brake drums, prise the
rubber plugs from the backplates, and use an
electric torch and mirror to inspect the linings
of the leading brake shoes. Check that the
thickness of the lining material on the brake
shoes is not less than the recommendation
given in the Specifications.
14 If it is difficult to determine the exact
thickness of the brake shoe linings, or if you
are at all concerned about the condition of the
shoes, then remove the rear drums for a more
comprehensive inspection (refer to Chap-
ter 9).
15 With the drum removed, check the shoe
return and hold-down springs for correct
installation, and check the wheel cylinders for
leakage of brake fluid. Check the friction
surface of the brake drums for scoring and
discoloration. If excessive, the drum should
be resurfaced or renewed.
16 Before refitting the wheels, check all
brake lines and hoses (refer to Chapter 9). On
completion, apply the handbrake and check
that the rear wheels are locked. The
handbrake also requires periodic adjustment,
and if its travel seems excessive, refer to
Section 27.
15 Roadwheel nut tightness check
1
1Apply the handbrake.
2 Remove the wheel covers, using the flat
end of the wheelbrace supplied in the tool kit
(on some models it will be necessary to
unscrew the retaining bolts with a special
key).

3Check that the roadwheel nuts are tightened
to the specified torque wrench setting.
4 Refit the wheel covers.
16 Door, tailgate and bonnet
check and lubrication
1
1Check that the doors and tailgate/boot lid
close securely. Check that the bonnet safety
catch operates correctly. Check the operation
of the door check straps.
2 Lubricate the hinges, door check straps,
the striker plates and the bonnet catch
sparingly with a little oil or grease.
17 Seat belt check
1
1 Check the seat belts for satisfactory
operation and condition. Inspect the webbing
for fraying and cuts. Check that they retract
smoothly and without binding into their reels.
2 Check that the seat belt mounting bolts are
tight, and if necessary tighten them to the
specified torque wrench settings as given in
Chapter 11.
18 Bodywork, paint and exterior trim check
1
1The best time to carry out this check is after
the car has been washed so that any surface
blemish or scratch will be clearly evident and
not hidden by a film of dirt.
2 Starting at one front corner check the
paintwork all around the car, looking for minor
scratches or more serious dents. Check all
the trim and make sure that it is securely
attached over its entire length.
3 Check the security of all door locks, door
mirrors, badges, bumpers, front grille and
wheel trim. Anything found loose, or in need of
further attention should be done with reference
to the relevant Chapters of this manual.
4 Rectify any problems noticed with the
paintwork or body panels as described in
Chapter 11.
19 Road test
1
Check the operation and
performance of the braking
system
1 Make sure that the vehicle does not pull to
one side when braking, and that the wheels
do not lock prematurely when braking hard.
2 Check that there is no vibration through the
steering when braking. 3
Check that the handbrake operates
correctly, without excessive movement of the
lever, and that it holds the vehicle stationary
on a slope.
4 Test the operation of the brake servo unit
as follows. With the engine switched off,
depress the footbrake four or five times to
exhaust the vacuum, then hold the pedal
depressed. Start the engine, and there should
be a noticeable “give” in the brake pedal as
vacuum builds up. Allow the engine to run for
at least two minutes, and then switch it off. If
the brake pedal is depressed again, it should
be possible to detect a hiss from the servo as
the pedal is depressed. After about four or five
applications, no further hissing should be
heard, and the pedal should feel considerably
firmer.
Steering and suspension
5 Check for any abnormalities in the steering,
suspension, handling or road “feel”.
6 Drive the vehicle, and check that there are
no unusual vibrations or noises.
7 Check that the steering feels positive, with
no excessive sloppiness or roughness, and
check for any suspension noises when
cornering and driving over bumps.
Drivetrain
8 Check the performance of the engine,
transmission and driveshafts.
9 Check that the engine starts correctly, both
when cold and when hot.
10 Listen for any unusual noises from the
engine and transmission.
11 Make sure that the engine runs smoothly
when idling, and that there is no hesitation
when accelerating.
12 On manual transmission models, check
that all gears can be engaged smoothly
without noise, and that the gear lever action is
not abnormally vague or “notchy”.
13 On automatic transmission models, make
sure that the drive seems smooth without
jerks or engine speed “flare-ups”. Check that
all the gear positions can be selected with the
vehicle at rest. If any problems are found, they
should be referred to a Ford dealer.
14 Listen for a metallic clicking sound from
the front of the vehicle, as the vehicle is driven
slowly in a circle with the steering on full-lock.
Carry out this check in both directions. If a
clicking noise is heard, this indicates wear in a
driveshaft joint, in which case renew the joint
if necessary.
Clutch
15 Check that the clutch pedal moves
smoothly and easily through its full travel, and
that the clutch itself functions correctly, with
no trace of slip or drag. If the movement is
uneven or stiff in places, check that the cable
is routed correctly, with no sharp turns.
16 Inspect both ends of the clutch inner
cable, both at the transmission end and inside
the car, for signs of wear and fraying.
Instruments and electrical
equipment
17 Check the operation of all instruments
and electrical equipment.
18 Make sure that all instruments read
correctly, and switch on all electrical equipment
in turn, to check that it functions properly.
20 Automatic transmission fluid level check
1
1The level of the automatic transmission fluid
should be carefully maintained. Low fluid level
can lead to slipping or loss of drive, while
overfilling can cause foaming, loss of fluid and
transmission damage.
2 The transmission fluid level should only be
checked when the transmission is hot (at its
normal operating temperature). If the vehicle
has just been driven over 10 miles (15 miles in
a cold climate), and the fluid temperature is 60
to 70ºC, the transmission is hot.
Caution: If the vehicle has just been driven
for a long time at high speed or in city
traffic in hot weather, or if it has been
pulling a trailer, an accurate fluid level
reading cannot be obtained. In these
circumstances, allow the fluid to cool
down for about 30 minutes.
3 Park the vehicle on level ground, apply the
handbrake, and start the engine. While the
engine is idling, depress the brake pedal and
move the selector lever through all the gear
positions three times, beginning and ending in
“P”.
4 Allow the engine to idle for one minute, then
(with the engine still idling) remove the
dipstick from its tube. Note the condition and
colour of the fluid on the dipstick.
5 Wipe the fluid from the dipstick with a clean
rag, and re-insert it into the filler tube until the
cap seats.
6 Pull the dipstick out again, and note the
fluid level. The level should be between
the “MIN” and “MAX” marks. If the level is
on the “MIN” mark, stop the engine, and add
the specified automatic transmission fluid
through the dipstick tube, using a clean funnel
if necessary. It is important not to introduce
dirt into the transmission when topping-up.
7 Add the fluid a little at a time, and keep
checking the level as previously described
until it is correct. The difference between the
“MIN” and “MAX” marks on the dipstick is
approximately 0.4 litres.
8 The need for regular topping-up of the
transmission fluid indicates a leak, which
should be found and rectified without delay.
9 The condition of the fluid should also be
checked along with the level. If the fluid on the
dipstick is black or a dark reddish-brown
colour, or if it has a burned smell, the fluid
should be changed. If you are in doubt about
the condition of the fluid, purchase some new
fluid, and compare the two for colour and smell.

21 Spark plug renewal and HTcomponent check
1
Note: Spark plug renewal at this service
interval is only necessary on the HCS, CVH
and PTE engines. On Zetec engines, the
recommended interval for spark plug renewal
is every 30 000 miles or three years.
Spark plug check and renewal
1 It is vital for the correct running, full
performance and proper economy of the engine
that the spark plugs perform with maximum
efficiency. The most important factor in ensuring
this is that the plugs fitted are appropriate for the
engine. The suitable type is given in the
Specifications Section at the beginning of this
Chapter, on the Vehicle Emissions Control
Information (VECI) label located on the
underside of the bonnet (only on models sold in
some areas) or in the vehicle’s Owner’s
Handbook. If the correct type is used and the
engine is in good condition, the spark plugs
should not need attention between scheduled
renewal intervals. Spark plug cleaning is rarely
necessary, and should not be attempted unless
specialised equipment is available, as damage
can easily be caused to the firing ends.
2 Spark plug removal and refitting requires a
spark plug socket, with an extension which can
be turned by a ratchet handle or similar. This
socket is lined with a rubber sleeve, to protect
the porcelain insulator of the spark plug, and to
hold the plug while you insert it into the spark
plug hole. You will also need a set of feeler
gauges, to check the spark plug electrode gap,
and a torque wrench to tighten the new plugs
to the specified torque (see illustration).
3 To remove the spark plugs, first open the
bonnet; the plugs are easily reached at the
top of the engine. Note how the spark plug
(HT) leads are routed and secured by clips,
and on some engines, how they’re positioned
along the channel in the cylinder head cover.
To prevent the possibility of mixing up spark
plug (HT) leads, it is a good idea to try to work
on one spark plug at a time.
4 If the marks on the original-equipment spark
plug (HT) leads cannot be seen, mark the leads
1 to 4, to correspond to the cylinder the lead
serves (No 1 cylinder is at the timing belt/chain
end of the engine). Pull the leads from the plugs
by gripping the rubber boot, not the lead,
otherwise the lead connection may be fractured.
5 It is advisable to soak up any liquid in the
spark plug recesses with a rag, and to remove
any dirt from them using a clean brush,
vacuum cleaner or compressed air before
removing the plugs, to prevent any dirt or
water from dropping into the cylinders. Warning: Wear eye protection
when using compressed air!
6 Unscrew the spark plugs, ensuring that the
socket is kept in alignment with each plug - if
the socket is forcibly moved to either side, the
porcelain top of the plug may be broken off. If
any undue difficulty is encountered when
unscrewing any of the spark plugs, carefully
check the cylinder head threads and tapered
sealing surfaces for signs of wear, excessive
corrosion or damage; if any of these
conditions is found, seek the advice of a Ford
dealer as to the best method of repair.
7 As each plug is removed, examine it as
follows - this will give a good indication of the
condition of the engine. If the insulator nose is
covered with light tan to greyish-brown
deposits, then the mixture is correct, and it is
likely that the engine is in good condition.
8 If the tip and insulator nose are covered
with hard black-looking deposits, then this is
indicative that the mixture is too rich. Should
the plug be black and oily, then it is likely that
the engine is fairly worn, as well as the mixture
being too rich.
9 If the insulator nose of the spark plug is clean and white, with no deposits, this is
indicative of a weak mixture.
10
If you are renewing the spark plugs,
purchase the new plugs, then check each of
them first for faults such as cracked insulators
or damaged threads. Note also that,
whenever the spark plugs are renewed as a
routine service operation, the spark plug (HT)
leads should be checked as described below.
11 The spark plug electrode gap is of
considerable importance as, if it is too large or
too small, the size of the spark and its
efficiency will be seriously impaired. The gap
should be set to the value given in the
Specifications Section of this Chapter. New
plugs will not necessarily be set to the correct
gap, so they should always be checked
before fitting.
12 The spark plug gap is correct when the
correct-size feeler gauge or wire gauge is a
firm sliding fit between the electrodes (see
illustrations) .
13 To adjust the electrode gap, bend open, or
close up, the outer plug electrode until the
correct gap is achieved (see illustration). The
centre electrode should never be bent, as this
may crack the insulation and cause plug failure,
Every 20 000 miles (32 000 km) or two years, whichever
comes first
Every 20 000 miles or two years1•19
21.12b Spark plug manufacturers

checking the gap - if the wire or feeler gauge
does not slide between the electrodes with a slight drag, adjustment is required
21.12a Measuring a spark plug gap with a feeler gauge21.2 Tools required for changing spark plugs
21.13 To change the gap, bend the outer
electrode only, and be very careful not to crack or chip the porcelain insulator
surrounding the centre electrode
1

http://vnx.su

if nothing worse. If the outer electrode is not
exactly over the centre electrode, bend it gently
to align them. Special spark plug gap adjusting
tools are available from motor accessory shops,
or from certain spark plug manufacturers.
14Before fitting the spark plugs, check that
the threaded connector sleeves at the top of
the plugs are tight, and that the plug exterior
surfaces and threads are clean. Brown
staining on the porcelain, immediately above
the metal body, is quite normal, and does not
necessarily indicate a “leak” between the
body and insulator.
15 Apply a smear of copper-based grease or
anti-seize compound to the threads of each
plug, and screw them in by hand where
possible. Take extra care to enter the plug
threads correctly, as the cylinder head is of
aluminium alloy.
16 When each spark plug is started correctly
on its threads, screw it down until it just seats
lightly, then tighten it to the specified torque
wrench setting. If a torque wrench is not
available - and this is one case where the use of
a torque wrench is strongly recommended -
tighten each spark plug through no more than
1/4 of a turn (CVH and PTE engines) or 1/16 of a
turn (HCS and Zetec engines) after it seats. HCS
and Zetec engines are fitted with taper-seat
spark plugs, identifiable by not having a sealing
washer, and these in particular should NEVER
be overtightened - their tapered seats mean
they are almost impossible to remove if abused.
17 Reconnect the spark plug (HT) leads in
their correct order, using a twisting motion on
the boot until it is firmly seated on the end of
the spark plug and on the cylinder head cover.
Spark plug (HT) lead, distributor
cap and rotor arm check
18 The spark plug (HT) leads should be
checked whenever the plugs themselves are renewed. Start by making a visual check of
the leads while the engine is running. In a
darkened garage (make sure there is
ventilation) start the engine and observe each
lead. Be careful not to come into contact with
any moving engine parts. If there is a break in
the lead, you will see arcing or a small spark
at the damaged area.
19
The spark plug (HT) leads should be
inspected one at a time, to prevent mixing up
the firing order, which is essential for proper
engine operation. Each original lead should
be numbered to identify its cylinder. If the
number is illegible, a piece of tape can be
marked with the correct number, and
wrapped around the lead (the leads should be
numbered 1 to 4, with No 1 lead nearest the
timing belt end of the engine). The lead can
then be disconnected.
20 Check inside the boot for corrosion, which
will look like a white crusty powder. Clean this
off as much as possible; if it is excessive, or if
cleaning leaves the metal connector too badly
eroded to be fit for further use, the lead must
be renewed. Push the lead and boot back
onto the end of the spark plug. The boot
should fit tightly onto the end of the plug - if it
doesn’t, remove the lead and use pliers
carefully to crimp the metal connector inside
the boot until the fit is snug.
21 Using a clean rag, wipe the entire length
of the lead to remove built-up dirt and grease. Once the lead is clean, check for burns,
cracks and other damage. Do not bend the
lead sharply, because the conductor might
break.
22 Disconnect the lead from the ignition coil
by pressing together the plastic retaining
catches (where fitted) and pulling the end
fitting off the coil terminal. Check for corrosion
and for a tight fit. If a meter with the correct
measuring range is available, measure the
resistance of the disconnected lead from its
coil connector to its spark plug connector. If
the resistance recorded for any of the leads
exceeds the value specified, all the leads
should be renewed as a set. Refit the lead to
the coil, noting that each coil terminal is
marked with its respective cylinder number,
so that there is no risk of mixing up the leads
and upsetting the firing order.
23 Inspect the remaining spark plug (HT)
leads, ensuring that each is securely fastened
at the distributor cap or ignition coil and spark
plug when the check is complete. If any sign
of arcing, severe connector corrosion, burns,
cracks or other damage is noticed, obtain new
spark plug (HT) leads, renewing them as a set.
If new spark plug leads are to be fitted,
remove and refit them one at a time, to avoid
mix-ups in the firing order. 24
On models with distributor ignition
systems, refer to Chapter 5B and remove the
distributor cap then thoroughly clean it inside
and out with a dry lint-free rag.
25 Examine the HT lead segments inside the
cap. If they appear badly burned or pitted
renew the cap. Also check the carbon brush
in the centre of the cap, ensuring that it is free
to move and stands proud of its holder. Make
sure that there are no sign of cracks or black
“tracking” lines running down the inside of the
cap, which will also mean renewal if evident.
26 Inspect the rotor arm checking it for
security and also for signs of deterioration as
described above.
27 Refit the cap as described in Chapter 5B
on completion.
22 Idle speed control valve cleaning and maintenance
1
Note: The idle speed control valve may be
mounted on the air cleaner, on the engine
compartment bulkhead, or on the side of the inlet
manifold according to valve make and year of
manufacture. Valves manufactured by Weber are
mounted on the air cleaner and only these valves
require the periodic maintenance described
below. Bulkhead and inlet manifold mounted
valves are manufactured by Hitachi and are
maintenance free. Refer to the warning note in
Section 1 of Chapter 4C before proceeding.
1 Remove the valve as described in Chap-
ter 4C, Section 14.
2 Immerse the valve head in a suitable
container filled with clean petrol, and allow it
to soak for approximately three minutes.
3 Clean the valve bore, slots and piston with
petrol, using a suitable lint-free cloth, then
gently move the piston up and down in its
bore using a small screwdriver (see
illustration) . Ensure that no cloth particles
enter the bore, and do not use the slots to
move the piston.
4 Rinse the valve again with clean petrol, then
dry it using an air line (or other source of
compressed air).
Warning: Wear eye protection
when using compressed air!
5 Clean the mating faces of the valve and the
air filter housing then refit as described in
Chapter 4C, Section 14.

1595Ford Fiesta Remake
It’s often difficult to insert spark plugs
into their holes without cross-threading
them. To avoid this possibility, fit a
short piece of rubber hose over the end
of the spark plug. The flexible hose
acts as a universal joint, to help align
the plug with the plug hole. Should the
plug begin to cross-thread, the hose
will slip on the spark plug, preventing
thread damage.
If new spark plug leads are tobe fitted, remove the leads
one at a time and fit each
new lead in exactly the same
position as the old one.

23 Coolant renewal
1
Note: If the antifreeze used is Ford’s own, the
coolant need not be renewed for the life of the
vehicle. If the vehicle’s history is unknown, if
antifreeze of lesser quality is known to be in
the system, or simply if you prefer to follow
conventional servicing intervals, the coolant
should be changed periodically (typically,
every 3 years) as described here. Refer also to
“Antifreeze - notes on renewal” in this
Section.
Warning: Do not allow
antifreeze to come in contact
with your skin or painted
surfaces of the vehicle. Flush
contaminated areas immediately with
plenty of water. Don’t store new coolant,
or leave old coolant lying around, where
it’s accessible to children or pets - they’re
attracted by its sweet smell. Ingestion of
even a small amount of coolant can be
fatal! Wipe up garage-floor and drip-pan
spills immediately. Keep antifreeze
containers covered, and repair cooling
system leaks as soon as they’re noticed.
Warning: Never remove the expansion
tank filler cap when the engine is running,
or has just been switched off, as the
cooling system will be hot, and the
consequent escaping steam and scalding
coolant could cause serious injury.
Coolant draining
Warning: Wait until the engine is
cold before starting this
procedure.
1 To drain the system, first remove the
expansion tank filler cap (see “Weekly
Checks” ).
2 If additional working clearance is required,
raise the front of the vehicle and support it securely on axle stands (see
“Jacking and
Vehicle Support” ).
3 Place a large drain tray beneath the
radiator, and unscrew the radiator drain plug -
you can use a small coin to do this, as the
plug’s slotted for this purpose (see
illustration) . Direct as much of the escaping
coolant as possible into the tray.
System flushing
4 With time, the cooling system may gradually
lose its efficiency, as the radiator core
becomes choked with rust, scale deposits
from the water, and other sediment (refer also
to “Antifreeze - notes on renewal” later in this
S ection). To minimise this, as well as using
only good-quality antifreeze and clean soft
water, the system should be flushed as follows
whenever any part of it is disturbed, and/or
when the coolant is renewed.
5 With the coolant drained, refit the drain
plug, and refill the system with fresh water.
Refit the expansion tank filler cap, start the
engine and warm it up to normal operating
temperature, then stop it and (after allowing it
to cool down completely) drain the system
again. Repeat as necessary until only clean
water can be seen to emerge, then refill finally
with the specified coolant mixture as
described below.
6 If only clean, soft water and good-quality
antifreeze (even if not to Ford’s specification)
has been used, and the coolant has been
renewed at the suggested intervals, the above
procedure will be sufficient to keep the
system clean for a considerable length of
time. If, however, the system has been
neglected, a more thorough operation will be
required, as follows.
7 First drain the coolant, then disconnect the
radiator top and bottom hoses. Insert a
garden hose into the top hose, and allow
water to circulate through the radiator until it
runs clean from the bottom outlet.
8 To flush the engine, insert the garden hose
into the thermostat water outlet, and allow
water to circulate until it runs clear from the
bottom hose. If, after a reasonable period, the
water still does not run clear, the radiator
should be flushed with a good proprietary
cleaning agent.
9 In severe cases of contamination, reverse-
flushing of the radiator may be necessary. To
do this, remove the radiator (Chapter 3), invert
it, and insert the garden hose into the bottom
outlet. Continue flushing until clear water runs
from the top hose outlet. A similar procedure
can be used to flush the heater matrix.
10 The use of chemical cleaners should be
necessary only as a last resort. Normally,
regular renewal of the coolant will prevent
excessive contamination of the system.
Coolant filling
11 With the cooling system drained and
flushed, ensure that all disturbed hose unions
are correctly secured, and that the radiator
drain plug is securely tightened. If it was
raised, lower the vehicle to the ground.
12 Prepare a sufficient quantity of the
specified coolant mixture (see below); allow
for a surplus, so as to have a reserve supply
for topping-up.
13 Slowly fill the system through the
expansion tank; since the tank is the highest
point in the system, all the air in the system
should be displaced into the tank by the rising
liquid. Slow pouring reduces the possibility of
air being trapped and forming airlocks.
14 Continue filling until the coolant level
reaches the expansion tank “MAX” level line,
then cover the filler opening to prevent
coolant splashing out.
15 Start the engine and run it at idle speed,
until it has warmed-up to normal operating
temperature and the radiator cooling fan has
cut in; watch the temperature gauge to check
for signs of overheating. If the level in the
expansion tank drops significantly, top-up to
the “MAX” level line, to minimise the amount
of air circulating in the system.
16 Stop the engine, allow it to cool down
completely (overnight, if possible), then
uncover the expansion tank filler opening and
top-up the tank to the “MAX” level line. Refit
the filler cap, tightening it securely, and wash
off any spilt coolant from the engine
compartment and bodywork.
17 After refilling, always check carefully all
components of the system (but especially any
unions disturbed during draining and flushing)
for signs of coolant leaks. Fresh antifreeze has
a searching action, which will rapidly expose
any weak points in the system.
18 If, after draining and refilling the system,
symptoms of overheating are found which did
not occur previously, then the fault is almost
certainly due to trapped air at some point in
the system, causing an airlock and restricting
the flow of coolant; usually, the air is trapped
because the system was refilled too quickly.
In some cases, airlocks can be released by
tapping or squeezing the various hoses. If the
problem persists, stop the engine and allow it
to cool down completely, before unscrewing
the expansion tank filler cap or disconnecting
hoses to bleed out the trapped air.
Antifreeze mixture
19 If the antifreeze used is not to Ford’s
specification, it should always be renewed at
the suggested intervals (typically, every 2 or
3 years). This is necessary not only to maintain
the antifreeze properties, but also to prevent
