FORD FIESTA 1989 Service Owner's Manual

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.

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

the corrosion which would otherwise occur
as the corrosion inhibitors become progress-
ively less effective. Always use an ethylene
glycol-based antifreeze which is suitable for
use in mixed-metal cooling systems.
20If the antifreeze used is to Ford’s
specification, the levels of protection it affords
are indicated in the Specifications Section of
this Chapter. To give the recommended
standard mixture ratio for this antifreeze, 40%
(by volume) of antifreeze must be mixed with
60% of clean, soft water; if you are using any
other type of antifreeze, follow its
manufacturer’s instructions to achieve the
correct ratio. It is best to make up slightly
more than the system’s specified capacity, so
that a supply is available for subsequent
topping-up.
21 Before adding antifreeze, the cooling
system should be completely drained,
preferably flushed, and all hoses checked for
condition and security. As noted earlier, fresh
antifreeze will rapidly find any weaknesses in
the system.
22 After filling with antifreeze, a label should
be attached to the expansion tank, stating the
type and concentration of antifreeze used,
and the date installed. Any subsequent
topping-up should be made with the same
type and concentration of antifreeze. If
topping-up using antifreeze to Ford’s
specification, note that a 50/50 mixture is
permissible, purely for convenience.
23 Do not use engine antifreeze in the
windscreen/tailgate washer system, as it will
damage the vehicle’s paintwork. A
screenwash additive should be added to the
washer system in its maker’s recommended
quantities.
Antifreeze - notes on renewal
24 Ford state that, where antifreeze to Ford
specification ESD-M97B-49-A is used, it will
last the lifetime of the vehicle. This is subject
to it being used in the recommended
concentration, unmixed with any other type of
antifreeze or additive, and topped-up when
necessary using only that antifreeze mixed 50/50 with clean water. If any other type of
antifreeze is added, the lifetime guarantee no
longer applies; to restore the lifetime
protection, the system must be drained and
thoroughly reverse-flushed before fresh
coolant mixture is poured in.
25
If the vehicle’s history (and therefore the
quality of the antifreeze in it) is unknown,
owners who wish to follow Ford’s
recommendations are advised to drain and
thoroughly reverse-flush the system before
refilling with fresh coolant mixture. If the
appropriate quality of antifreeze is used, the
coolant can then be left for the life of the
vehicle.
26 If any antifreeze other than Ford’s is to be
used, the coolant must be renewed at regular
intervals to provide an equivalent degree of
protection; the conventional recommendation
is to renew the coolant every two or three
years.
27 The above assumes the use of a mixture
(in exactly the specified concentration) of
clean, soft water and of antifreeze to Ford’s
specification or equivalent. It is also assumed
that the cooling system is maintained in a
scrupulously-clean condition, by ensuring that
only clean coolant is added on topping-up,
and by thorough reverse-flushing whenever
the coolant is drained.
General cooling system checks
28 The engine should be cold for the cooling
system checks, so perform the following
procedure before driving the vehicle, or
after it has been shut off for at least three
hours.
29 Remove the expansion tank filler cap, and
clean it thoroughly inside and out with a rag.
Also clean the filler neck on the expansion
tank. The presence of rust or corrosion in the
filler neck indicates that the coolant should be
changed. The coolant inside the expansion
tank should be relatively clean and
transparent. If it is rust-coloured, drain and
flush the system, and refill with a fresh coolant
mixture.
30 Carefully check the radiator hoses and heater hoses along their entire length; renew
any hose which is cracked, swollen or
deteriorated (see Section 5).
31
Inspect all other cooling system
components (joint faces, etc.) for leaks. A leak
in the cooling system will usually show up as
white- or rust-coloured deposits on the area
adjoining the leak. Where any problems of this
nature are found on system components,
renew the component or gasket with
reference to Chapter 3.
32 Clean the front of the radiator with a soft
brush to remove all insects, leaves, etc,
embedded in the radiator fins. Be careful not
to damage the radiator fins, or cut your fingers
on them.
24 Air cleaner element renewal
1
1 The air cleaner filter element is located in
the air cleaner assembly mounted either on
top of the carburettor or CFi unit, or on the
left-hand or right-hand side of the engine
compartment at the front. Remove the air
cleaner lid as follows according to type.

All models
10Lift out the element, and wipe out the
housing (see illustrations) . Check that no
foreign matter is visible, either in the air inlet
or in the air mass meter, as applicable.
11 If carrying out a routine service, the
element must be renewed regardless of its
apparent condition. Note that on models so
equipped, the small foam PCV filter in the rear
right-hand corner of the air cleaner housing
must be cleaned whenever the air filter
element is renewed (see Section 25).
12 If you are checking the element for any
other reason, inspect its lower surface; if it is
oily or very dirty, renew the element. If it is
only moderately dusty, it can be re-used after
blowing it clean from the upper to the lower
surface with compressed air. Warning: Wear eye protection
when using compressed air!
Because it is a pleated-paper
type filter, it cannot be washed
or re-oiled. If it cannot be cleaned satisfactorily with compressed air,
discard and renew it.
Caution: Never drive the vehicle with the
air cleaner filter element removed.
Excessive engine wear could result, and
backfiring could even cause a fire under
the bonnet.
13
Refitting is the reverse of the removal
procedure. Ensure that the element and cover
are securely seated, so that unfiltered air
cannot enter the engine.Air cleaner temperature control
system check (carburettor
models)
14 In order for the engine to operate
efficiently, the temperature of the air entering
the inlet system must be controlled within
certain limits.
15 The air cleaner has two sources of air, one
direct from the outside of the engine
compartment, and the other from a shroud on
the exhaust manifold. On HCS engines, a
wax-controlled thermostatic valve controls a
flap inside the air cleaner inlet. When the
ambient air temperature is below a
predetermined level, the flap admits air
heated from the exhaust manifold shroud; as
the ambient temperature rises, the flap opens
to admit more cool air from the engine
compartment until eventually it is fully open. A
similar system is used on CVH engines,
except that a vacuum actuator modifies any opening or closing action of the temperature
sensor on the flap valve, according to the level
of the inlet manifold vacuum under running
conditions.
HCS engines
16
This check must be made when the
engine is cold. Detach and remove the air
cleaner inlet trunking. Examine the position of
the check valve within the duct. When the
underbonnet air temperature is below 28ºC,
the valve must be open to allow hot air to
enter the filter (see illustration) .
17 Refit the inlet trunking. Start the engine
and run it until it reaches its normal operating
temperature, then stop the engine, remove
the inlet trunking and check that the valve has
closed off the air passage from the exhaust
and opened the main (cool) air inlet.
18 If the flap does not operate correctly,
check that it is not seized. Apart from this
there is no adjustment possible, and the unit
should be renewed if faulty. Refit the air inlet
trunking on completion.
CVH engines
19 This check must be made when the
engine is cold. Disconnect the main air inlet
duct, and visibly check that the flap to the

engine idling, the hot-air inlet is open to allow
warm air from the exhaust manifold area to
enter the air cleaner. If the flap operates as
described, it is functioning correctly (see
illustration) .
21 If the flap fails to operate as described,
check the condition of the vacuum pipe and
its connections, and check that the flap valve
has not seized. If these are in order, either the
temperature sensor or vacuum actuator is
faulty, and a new air cleaner assembly must
be obtained. Refit the main air duct on
completion.
25 Emission control system
check
1
General
1Of the emission control systems that may
be fitted, only the crankcase ventilation
system and the evaporative emission control
systems require regular checking, and even
then, the components of these systems
require minimal attention.
2 Should it be felt that the other systems are
not functioning correctly, the advice of a
dealer should be sought.
Crankcase ventilation system
3 The function of the crankcase ventilation
system is to reduce the emission of unburned
hydrocarbons from the crankcase, and to
minimise the formation of oil sludge. By
ensuring that a depression is created in the
crankcase under most operating conditions,
particularly at idle, and by positively inducing
fresh air into the system, the oil vapours and
“blow-by” gases collected in the crankcase
are drawn from the crankcase, through the air
cleaner or oil separator, into the inlet tract, to
be burned by the engine during normal
combustion.
4 On HCS engines, the system consists of a
vented oil filler cap (with an integral mesh
filter) and a hose connecting it to the oil
separator/engine breather valve connector on
the underside of the air cleaner housing. A further hose leads from the adapter/filter to
the inlet manifold.
5
On CVH engines, a closed-circuit type
crankcase ventilation system is used, the
function of which is basically the same as that
described for the HCS engine types, but the
breather hose connects directly to the rocker
cover. A separate filter is fitted in the hose to
the rocker cover in certain applications (see
illustration) .
6 The system fitted to the PTE engines is
similar to that used on the earlier (CVH)
engines on which these engines are based,
but with revisions to the hose arrangement to
suit the remotely sited air cleaner and fuel
injection system layout.
7 On Zetec engines, the crankcase ventilation
system main components are the oil
separator mounted on the front (radiator) side
of the cylinder block/crankcase, and the
Positive Crankcase Ventilation (PCV) valve set
in a rubber grommet in the separator’s left-
hand upper end. The associated pipework
consists of a crankcase breather pipe and two
flexible hoses connecting the PCV valve to a
union on the left-hand end of the inlet
manifold, and a crankcase breather hose
connecting the cylinder head cover to the air
cleaner assembly. A small foam filter in the
air cleaner prevents dirt from being drawn
directly into the engine.
8 Check that all components of the system
are securely fastened, correctly routed (with
no kinks or sharp bends to restrict flow) and in
sound condition; renew any worn or damaged
components.
9 On HCS engines, remove and inspect the
oil filler cap to ensure that it is in good
condition, and not blocked up with sludge.
10 Disconnect the hoses at the cap, and
clean the cap if necessary by brushing the
inner mesh filter with petrol, and blowing
through with light pressure from an air line.
Renew the cap if it is badly congested.
11 If oil leakage is noted, disconnect the
various hoses and pipes, and check that all
are clear and unblocked. Remove the air
cleaner lid, and check that the hose from the
cylinder head cover to the air cleaner housing
is clear and undamaged. 12
Where fitted, the PCV valve is designed to
allow gases to flow out of the crankcase only,
so that a depression is created in the
crankcase under most operating conditions,
particularly at idle. Therefore, if either the oil
separator or the PCV valve are thought to be
blocked, they must be renewed (see Chap-
ter 4E). In such a case, however, there is
nothing to be lost by attempting to flush out
the blockage using a suitable solvent. The
PCV valve should rattle when shaken.
13 While the air filter element is removed (see
Section 24), wipe out the housing, and on
Zetec engines, withdraw the small foam filter
from its location in the rear right-hand corner
of the housing (see illustration) . If the foam is
badly clogged with dirt or oil, it must be
cleaned by soaking it in a suitable solvent,
and allowed to dry before being refitted.
Evaporative emission control
systems
14 Refer to the checks contained in Chap-
ter 4E.
26 Automatic transmission fluid renewal

1The automatic transmission fluid should
only be changed when the transmission is
cold.
2 Position the vehicle over an inspection pit,
on vehicle ramps, or jack it up and securely
support it on axle stands, but make sure that
it is level.
3 Place a suitable container beneath the drain
plug on the transmission sump pan. Remove
the transmission fluid dipstick to speed up the
draining operation.
4 Thoroughly clean the area around the drain
plug in the transmission sump pan, then
unscrew the plug and allow the fluid to drain
into the container.
5 When all the fluid has drained (this may take
quite some time) clean the drain plug, then
refit it together with a new seal and tighten it
securely.
6 Place a funnel with a fine mesh screen in
the dipstick tube, and fill the transmission with

the specified type of fluid. It is essential that
no dirt is introduced into the transmission
during this operation.
7Depending on the extent to which the fluid
was allowed to drain, it is possible that the
amount of fluid required when filling the
transmission may be more than the specified
amount (see “Lubricants, fluids and tyre
pressures” ). However, due to fluid remaining in
the system, it is more likely that less than the
specified amount will be required. Add about
half the specified amount, then run the engine
up to its normal operating temperature and
check the level on the dipstick. When the level
approaches the maximum mark, proceed as
detailed in Section 20 to check the level and
complete the final topping-up as described.

correctly routed and secured by the retaining
clips at the appropriate points under the vehicle.
3 The handbrake is checked for adjustment
by measuring the amount of movement
possible in the handbrake adjuster plungers.
These are located on the inside face of each
rear brake backplate (see illustration) . Thetotal movement of the two plungers combined
should be between 0.5 and 2.0 mm. If the
movement measured is outside of this
tolerance, the handbrake is in need of
adjustment. Adjustment is made altering the
position of the in-line cable adjuster sleeve.
4
When adjustment to the handbrake is
necessary, a new adjustment sleeve locking
pin will be required, and this must therefore
be obtained before making the adjustment.
5 To adjust the handbrake, first ensure that it
is fully released, then firmly apply the
footbrake a few times to ensure that the rear
brake adjustment is taken up by the automatic
adjusters. Extract the locking pin from
the adjuster sleeve (see illustration), then
turn the sleeve to set the combined move-
ment of the plungers within the tolerance range specified (0.5 to 2.0 mm). Turn the
locking nut by hand as tight as is possible
(two clicks) against the adjustment sleeve.
Now grip the locknut with a suitable wrench,
and turn it a further two clicks (maximum).
6
Secure the adjustment by inserting the new
lock pin.
7 Check that the operation of the handbrake
is satisfactory, then lower the vehicle to the
ground, apply the handbrake and remove the
chocks from the front wheels.

Warning: Petrol is extremely
flammable, so extra precautions
must be taken when working on
any part of the fuel system. Do
not smoke, or allow open flames or bare
light bulbs, near the work area. Also, do
not work in a garage if a natural gas-type appliance with a pilot light is present.
While performing any work on the fuel system, wear safety glasses, and have a
suitable (Class B) fire extinguisher on
hand. If you spill any fuel on your skin,
rinse it off immediately with soap and
water.
1
On fuel injection engines, an in-line fuel
filter is provided in the fuel pump outlet line.
The filter is located in the engine compartment
either below and behind the battery, or on the
left-hand side of the engine compartment
bulkhead. The renewal procedure is the same
for both locations. The filter performs a vital
role in keeping dirt and other foreign matter
out of the fuel system, and so must be renewed at regular intervals, or whenever you
have reason to suspect that it may be
clogged. It is always unpleasant working
under a vehicle - pressure-washing or hosing
clean the underbody in the filter’s vicinity will
make working conditions more tolerable, and
will reduce the risk of getting dirt into the fuel
system.
2
Depressurise the fuel system as described
in the relevant Part of Chapter 4.
3 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1), then position
a suitable container beneath the fuel filter to
catch escaping fuel. Have a rag handy to soak

up the fuel when the feed and outlet pipe
unions are disconnected.
4On models without quick-release couplings
on the fuel lines, slowly slacken the fuel feed
pipe union allowing the pressure in the fuel
pipe to reduce. When the pressure is fully
released, disconnect the fuel feed and outlet
pipe unions.
5 On models with quick-release couplings on
the fuel lines, release the fuel feed and outlet
pipe unions from the filter, by squeezing
together the protruding locking lugs on each
union, and carefully pulling the union off the
filter stub (see illustration) . Where the unions are colour-coded, the feed and outlet pipes
cannot be confused; where both unions are
the same colour, note carefully which pipe is
connected to which filter stub, and ensure that
they are correctly reconnected on refitting.
6
Noting the arrows and/or other markings on
the filter showing the direction of fuel flow
(towards the engine), slacken the filter clamp
bolt and withdraw the filter from the car (see
illustrations) . Note that the filter will still
contain fuel; care should be taken, to avoid
spillage and to minimise the risk of fire.
7 On installation, slide the filter into its clamp
so that the arrow marked on it faces the correct way, then reconnect and tighten the
pipe unions or slide each pipe union on to its
(correct) respective filter stub, and press it
down until the locking lugs click into their
groove. Tighten the clamp bolt carefully, until
the filter is just prevented from moving; do not
overtighten, or the filter casing may be
crushed.
8
Refit the fuel pump fuse and reconnect the
battery earth terminal, then switch the ignition
on and off five times, to pressurise the
system. Check for any sign of fuel leakage
around the filter unions before lowering the
vehicle to the ground and starting the engine.

The procedure is similar to that for the

in Chapter 9, except that the brake fluid
reservoir should be emptied by syphoning,
and allowance should be made for the old
fluid to be removed from the circuit when
bleeding a section of the circuit.

2A•2 HCS engine in-car repair procedures
1595Ford Fiesta Remake
1 General information
How to use this Chapter
This Part of Chapter 2 is devoted to repair
procedures possible while the engine is still
installed in the vehicle, and includes only the
Specifications relevant to those procedures.
Similar information concerning the 1.4 and
1.6 litre CVH and PTE engines, and the 1.6
and 1.8 litre Zetec engines, will be found in
Parts B and C of this Chapter respectively.
Since these procedures are based on the
assumption that the engine is installed in the
vehicle, if the engine has been removed from
the vehicle and mounted on a stand, some
of the preliminary dismantling steps outlined
will not apply. Information concerning engine/transmission
removal and refitting, and engine overhaul, can
be found in Part D of this Chapter, which also
includes the Specifications relevant to those
procedures.
Engine description
The engine is an overhead valve, water-
cooled, four cylinder in-line design,
designated HCS (High Compression Swirl).
The engine is mounted transversely at the
front of the vehicle together with the
transmission to form a combined power unit. The crankshaft is supported in three or five
shell-type main bearings. The connecting rod
big-end bearings are also split shell-type, and
are attached to the pistons by interference-fit
gudgeon pins. Each piston is fitted with two
compression rings and one oil control ring. The camshaft, which runs on bearings
within the cylinder block, is chain-driven from
the crankshaft, and operates the valves via
pushrods and rocker arms. The valves are
each closed by a single valve spring, and
operate in guides integral in the cylinder head. The oil pump is mounted externally on the
crankcase, incorporates a full-flow oil filter,
and is driven by a skew gear on the camshaft.
On carburettor versions, the fuel pump is also
driven from the camshaft, via an eccentric
lobe.
Repair operations possible with
the engine in the car
The following work can be carried out with
the engine in the car:
a) Compression pressure - testing.
b) Cylinder head rocker cover - removal
and refitting.
c) Valve clearances - adjustment.
d) Rocker shaft assembly - removal,
inspection and refitting.
e) Cylinder head - removal and refitting
f) Cylinder head and pistons - decarbonising.
g) Crankshaft pulley - removal and refitting.
h) Crankshaft oil seals - renewal.
i) Timing chain, sprockets and tensioner -
removal, inspection and refitting.
j) Oil filter renewal.
k) Oil pump - removal and refitting.
l) Sump - removal and refitting.
m) Flywheel - removal, inspection and
refitting.
n) Engine/transmission mountings -
inspection and renewal.

connecting rods (after removing the cylinder
head and sump) without removing the engine.
However, this is not recommended. Work of
this nature is more easily and thoroughly
completed with the engine on the bench, as
described in Chapter 2D.
2 Compression test-
description and interpretation
2
1 When engine performance is down, or if
misfiring occurs which cannot be attributed to
the ignition or fuel systems, a compression
test can provide diagnostic clues as to the
engine’s condition. If the test is performed
regularly, it can give warning of trouble before
any other symptoms become apparent.
2 The engine must be fully warmed-up to
normal operating temperature, the oil level
must be correct and the battery must be fully
charged. The aid of an assistant will also be
required.
3 On fuel injection engines, refer to Chap-
ter 12 and remove the fuel pump fuse from the
fusebox. Now start the engine and allow it to
run until it stalls.
4 Disable the ignition system by
disconnecting the multi-plug from the DIS or
E-DIS ignition coil. Remove all the spark plugs
with reference to Chapter 1 if necessary.
5 Fit a compression tester to the No 1
cylinder spark plug hole - the type of tester
which screws into the plug thread is to be
preferred.
6 Arrange for an assistant to hold the
accelerator pedal fully depressed to the floor,
while at the same time cranking the engine
over for several seconds on the starter motor.
Observe the compression gauge reading. The
compression will build up fairly quickly in a
healthy engine. Low compression on the first
stroke, followed by gradually-increasing
pressure on successive strokes, indicates
worn piston rings. A low compression on the
first stroke which does not rise on successive
strokes, indicates leaking valves or a blown
head gasket (a cracked cylinder head could
also be the cause). Deposits on the underside
of the valve heads can also cause low
compression. Record the highest gauge
reading obtained, then repeat the procedure
for the remaining cylinders.
7 Due to the variety of testers available, and
the fluctuation in starter motor speed when
cranking the engine, different readings
are often obtained when carrying out
the compression test. For this reason, actual
compression pressure figures are not quoted
by Ford. However, the most important factor
is that the compression pressures are uniform
in all cylinders, and that is what this test is
mainly concerned with.
8 Add some engine oil (about three squirts
from a plunger type oil can) to each cylinder
through the spark plug holes, and then repeat
the test. 9
If the compression increases after the oil is
added, it is indicative that the piston rings are
definitely worn. If the compression does not
increase significantly, the leakage is occurring
at the valves or the head gasket. Leakage
past the valves may be caused by burned
valve seats and/or faces, or warped, cracked
or bent valves.
10 If two adjacent cylinders have equally low
compressions, it is most likely that the head
gasket has blown between them. The
appearance of coolant in the combustion
chambers or on the engine oil dipstick would
verify this condition.
11 If one cylinder is about 20 percent lower
than the other, and the engine has a slightly
rough idle, a worn lobe on the camshaft could
be the cause.
12 On completion of the checks, refit the
spark plugs and reconnect the HT leads and
the ignition coil plug. Refit the fuel pump fuse
to the fusebox.
3 Top Dead Centre (TDC) for No 1 piston - locating
2
1Top dead centre (TDC) is the highest point
of the cylinder that each piston reaches as the
crankshaft turns. Each piston reaches its TDC
position at the end of its compression stroke,
and then again at the end of its exhaust
stroke. For the purpose of engine timing, TDC
at the end of the compression stroke for No 1
piston is used. On the HCS engine, No 1
cylinder is at the crankshaft pulley/timing
chain end of the engine. Proceed as follows.
2 Ensure that the ignition is switched off.
Disconnect the HT leads from the spark plugs,
then unscrew and remove the plugs as
described in Chapter 1.
3 Turn the engine over by hand (using a
spanner on the crankshaft pulley) to the point
where the timing mark on the crankshaft
pulley aligns with the TDC (0) mark or TDC
reference pointer on the timing cover (see
illustration) . As the pulley mark nears the
timing mark, the No 1 piston is simultaneously
approaching the top of its cylinder. To ensure
that it is on its compression stroke, place a
finger over the No 1 cylinder plug hole, and feel to ensure that air pressure exits from the
cylinder as the piston reaches the top of its
stroke.
4
A further check to ensure that the piston is
on its compression stroke can be made by
first removing the air cleaner (refer to the
relevant Part of Chapter 4), then unbolting and
removing the rocker cover, so that the
movement of the valves and rockers can be
observed.
5 With the TDC timing marks on the
crankshaft pulley and timing cover in
alignment, rock the crankshaft back and forth
a few degrees each side of this position, and
observe the action of the valves and rockers
for No 1 cylinder. When No 1 piston is at the
TDC firing position, the inlet and exhaust valve
of No 1 cylinder will be fully closed, but the
corresponding valves of No 4 cylinder will be
seen to rock open and closed.
6 If the inlet and exhaust valves of No 1
cylinder are seen to rock whilst those of
No 4 cylinder are shut, the crankshaft will
need to be turned one full rotation to bring
No 1 piston up to the top of its cylinder on the
compression stroke.
7 Once No 1 cylinder has been positioned at
TDC on the compression stroke, TDC for any
of the other cylinders can then be located by
rotating the crankshaft clockwise (in its
normal direction of rotation), 180º at a time,
and following the firing order (see
Specifications).
4 Cylinder head rocker cover -
removal and refitting
1
Removal
1 Where necessary for access, remove the air
cleaner as described in the relevant Part of
Chapter 4.
2 Detach the HT leads from the spark plugs.
Pull on the connector of each lead (not the
lead itself), and note the order of fitting.
3 Remove the engine oil filler cap and
breather hose (where fitted).
4 Unscrew the four retaining bolts, and lift the
rocker cover clear of the cylinder head.
Remove the gasket.
