4Carefully check the condition of all coolant,
fuel, power steering and brake hoses. Renew
any hose which is cracked, swollen or
deteriorated. Cracks will show up better if the
hose is squeezed. Pay close attention to the
hose clips that secure the hoses to the system
components. Hose clips can pinch and
puncture hoses, resulting in leaks. If wire type
hose clips are used, it may be a good idea to
replace them with screw-type clips.
5With the vehicle raised, inspect the fuel
tank and filler neck for punctures, cracks and
other damage. The connection between the
filler neck and tank is especially critical.
Sometimes a rubber filler neck or connecting
hose will leak due to loose retaining clamps or
deteriorated rubber.
6Similarly, inspect all brake hoses and metal
pipes. If any damage or deterioration is
discovered, do not drive the vehicle until the
necessary repair work has been carried out.
Renew any damaged sections of hose or pipe.
7Carefully check all rubber hoses and metal
fuel lines leading away from the petrol tank.
Check for loose connections, deteriorated
hoses, crimped lines and other damage. Pay
particular attention to the vent pipes and
hoses which often loop up around the filler
neck and can become blocked or crimped.
Follow the lines to the front of the vehicle
carefully inspecting them all the way. Renew
damaged sections as necessary.
8From within the engine compartment,
check the security of all fuel hose attachments
and pipe unions, and inspect the fuel hoses
and vacuum hoses for kinks, chafing and
deterioration.
9Where applicable, check the condition of
the oil cooler hoses and pipes.
10Check the condition of all exposed wiring
harnesses.
1Periodically check the belts for fraying or
other damage. If evident, renew the belt.
2If the belts become dirty, wipe them with a
damp cloth using a little detergent only.
3Check the tightness of the anchor bolts and
if they are ever disconnected, make quite sure
that the original sequence of fitting of
washers, bushes and anchor plates is
retained.
With the vehicle raised on a hoist or
supported on axle stands, check the exhaust
system for signs of leaks, corrosion or
damage and check the rubber mountings for
condition and security. Where damage or
corrosion are evident, renew the system
complete or in sections, as applicable, using
the information given in Chapter 4.With the wheels on the ground, slacken each
wheel nut by a quarter turn, then retighten it
immediately to the specified torque.
Remove and clean the oil filler cap of any
sludge build-up using paraffin.
Inspect the vent hose for blockage or
damage. A blocked hose can cause a build-
up of crankcase pressure, which in turn can
cause oil leaks.
Ford VV carburettor
1Ensure that the air cleaner is correctly fitted,
and that all vacuum hoses and pipes are
securely connected and free from restrictions,
then run the engine until it is at normal
operating temperature.
2Stop the engine, and connect a tachometer
and an exhaust gas analyser in accordance
with the manufacturer’s instructions.
3Start the engine and run it at 3000 rpm for
30 seconds, ensuring that all electrical loads
are switched off (headlamps, heater blower
etc), then allow the engine to idle and check
the idle speed and CO content. Note that the
CO reading will initially rise, then fall and finally
stabilise after between 5 and 25 seconds.4If necessary, adjust the idle speed screw to
give the specified idle speed (see
illustration).
5Checking and adjustment should be
completed within 30 seconds of the meter
readings stabilising. If this has not been
possible, repeat paragraphs 3 and 4, ignoring
the reference to starting the engine.
Weber 2V carburettor
Models without stepper motor
6Proceed as described for the Ford VV
carburettor but note the following:
7It is permissible to loosen the air cleaner
securing screws to allow easier access to the
carburettor adjustment screws but ensure
that all vacuum hoses and pipes are securely
connected. For adjustment screw location
(see illustrations).
Models with stepper motor (ESC II
system)
8The idle speed is controlled by the ESC II
module via the stepper motor. The only idle
speed adjustment possible is provided by the
“idle speed adjustment” wire, which can be
earthed to raise the idle speed by 75 rpm. No
other method of idle speed adjustment should
be attempted. If the idle speed is incorrect,
the problem should be referred to a Ford
dealer, as the problem probably lies in the
ESC II module for which special diagnostic
equipment is required.

applicable), before proceeding.
Before carrying out any carburettor
adjustments, ensure that the ignition
timing and spark plug gaps are set as
specified. To carry out the adjustments an
accurate tachometer and an exhaust gas
analyser (CO meter) will be required.

8Tighten the alternator mounting and
adjustment nuts and bolts in the order shown
(see illustration).
9Where applicable, refit and tension the air
conditioning compressor drivebelt.
10Reconnect the battery negative lead.
11Drivebelt tension should be rechecked
and if necessary adjusted after the engine has
been run for a minimum of ten minutes.
DOHC models
12Three different types of drivebelt
arrangement are used, depending on model
(see illustrations).On models without powersteering, the drivebelt is tensioned by moving
the alternator. On models with power steering,
the power steering pump is also driven by the
coolant pump/alternator drivebelt and an
automatic belt tensioner is fitted (see
illustration).On models with air conditioning,
the drivebelt drives the alternator, coolant
pump, power steering pump and air
conditioning compressor, and an automatic
belt tensioner is fitted.
13On models without power steering, loosen
the alternator mounting and adjustment bolts,
and pivot the alternator towards the cylinder
block. Slip the drivebelt from the pulleys.
14On models with power steering, the
automatic tensioner can be released using a
17 mm socket and a wrench on the boss in
the centre of the pulley. Lever the tensioner
assembly clockwise, slide the belt from the
pulleys, then slowly release the tensioner.
15To fit a new belt on models without
power steering, slide the belt over the pulleys,
then lever the alternator away from the
cylinder block until the correct belt tension is
achieved. Lever the alternator using a plastic
or wooden lever at the pulley end to prevent
damage. It is helpful to partially tighten the
adjustment link bolt before tensioning the
drivebelt. When the correct tension is
achieved, tighten all the bolts.
16To fit a new belt on models with power
steering, lever the tensioner clockwise as
during removal, then slide the belt over the
pulleys, and slowly release the tensioner.
1The battery fitted as original equipment is
“maintenance-free”, and requires nomaintenance apart from having the case kept
clean, and the terminals clean and tight.
2To clean the battery terminals disconnect
them, after having first removed the cover
(later models) - negative earth first. Use a wire
brush or abrasive paper to clean the
terminals. Bad corrosion should be treated
with a solution of bicarbonate of soda, applied
with an old toothbrush. Do not let this solution
get inside the battery.
3Coat the battery terminals with petroleum
jelly or a proprietary anti-corrosive compound
before reconnecting them. Reconnect and
tighten the positive (live) lead first, followed by
the negative (earth) lead. Do not overtighten.
4Keep the top of the battery clean and dry.
Inspect the battery tray for corrosion, and
make good as necessary.
SOHC engines
1The valve clearances must be checked with
the engine cold. On carburettor models
remove the air cleaner.
2Disconnect the HT leads from the spark
plugs and release them from the clips on the
camshaft cover.
3On fuel injection models, unbolt and
remove the bracing strut securing the inlet
manifold to the right-hand side of the cylinder
head.
4Where applicable, unclip any hoses and
wires from the camshaft cover, then unscrew
the securing bolts and remove the camshaft
cover and gaskets. Take care not to lose the
spacer plates which fit under the bolt heads,
where applicable.

Caution: Before carrying out
any work on the vehicle battery,
read through the precautions
given in “Safety first!” at the
beginning of this manual.
It will be easier to turn the
engine by hand if the spark
plugs are removed but take
care not to allow dirt to enter
the spark plug holes.

6Fit the new filter, ensuring that the arrows on
the filter body point in the direction of fuel flow.
7Tighten the clamp screw, and reconnect
the fuel inlet and outlet unions. Ensure that the
unions are correctly connected.
8Reconnect the battery negative lead, and
check the fuel line unions for leaks,
pressurising the system by switching the
ignition on and off several times.
All models except 2.0 litre SOHC
9Proceed as described for the 2.0 litre SOHCmodels, noting the following points.
10The fuel filter is located under the rear of
the vehicle, above the driveshaft (see
illustration). For access to the filter, chock
the front wheels, then jack up the rear of the
vehicle and support it on axle stands.
11To remove the filter, the mounting bracket
must first be removed from the floor, after
unscrewing the securing bolt. The filter can
then be removed from the bracket after
unscrewing the clamp bolt.On carburettor model SOHC engines,
renew the crankcase ventilation vent valve by
pulling it from the oil separator and loosening
the hose clip (see illustration). Fit the new
valve, tighten the clip, and insert it into the oil
separator grommet.
42Crankcase ventilation vent
valve renewal
If in doubt as to the condition of any of the
brake system seals and hoses, then renew
defective items whilst referring to the relevant
Sections of Chapter 10.
1An assistant and bleeding equipment will
be needed. A considerable quantity of
hydraulic fluid will be required - probably
about 2 litres (nearly half a gallon).
2Slacken the front wheel nuts. Raise and
support the front of the vehicle and remove
the front wheels.
3Remove the hydraulic fluid reservoir cap.
4Open both front bleed screws one full turn.
Attach one bleed tube to each screw, placing
the free end of each tube in a jar.
5Pump the brake pedal to expel fluid from
the bleed screws. Pause after each upstroke
to allow the master cylinder to refill.
6When air emerges from both bleed screws,
stop pumping. Detach the left-hand caliper
without disconnecting it and remove the
inboard brake pad.
7Depress the caliper piston, using a
purpose-made tool or a blunt item such as a
tyre lever, to force more fluid out of the
caliper. Hold the piston depressed and have
the assistant pump the pedal until air emerges
from the bleed screw again.8Tighten the bleed screw on the left-hand
caliper. Loosely refit the caliper and pad so
that the piston is not accidentally ejected.
9Repeat the purging operation on the right-
hand caliper, but do not refit it or tighten the
bleed screw yet.
10Fill the reservoir with fresh hydraulic fluid.
Position the bleed jar for the right-hand
caliper at least 300 mm (1 foot) above the
level of the bleed screw.
11Have the assistant pump the brake pedal
until fluid free of bubbles emerges from the
bleed screw. Tighten the bleed screw at the
end of a downstroke.
12Place a piece of wood in the caliper jaws
to limit piston travel. Keep your fingers clear
of the piston. Have the assistant depress the
brake pedal gentlyin order to move the
caliper piston out.
13With the pedal held depressed, slacken
the bleed screw on the right-hand caliper and
again depress the piston. Tighten the bleed
screw when the piston is retracted. The pedal
can now be released.
14Disconnect the bleed tube. Refit the right-
hand brake pad and caliper.
15Remove the left-hand caliper and inboard
pad again. Carry out the operations described
in paragraphs 10 to 14 on the left-hand
caliper.
16Bleed the rear brakes (Chapter 10).
17Refit the front wheels, lower the vehicle
and tighten the wheel nuts.
18Pump the brake pedal to bring the pads
up to the discs, then make a final check of the
hydraulic fluid level. Top-up and refit the
reservoir cap.Camshaft drivebelt renewal is
recommended as a precautionary measure for
SOHC engines but is compulsory for CVH
engines. Refer to Chapter 2 for the
appropriate renewal procedure.
1Disconnect the battery negative lead.
2It is preferable to drain the cooling system
with the engine cold. If this is not possible,
take precautions against scalding when
removing the expansion tank cap. Place a
thick rag over the cap and slacken the cap a
little to release any pressure. When all
pressure has been released, carry on
unscrewing the cap and remove it.
3Early models have no radiator drain plug, so
the radiator must be drained by detaching the
bottom coolant hose from the outlet on the
right-hand side of the radiator. Later SOHC
models have a drain plug located in the base
of the left-hand radiator end tank, whilst all
CVH models have a drain plug in the
right-hand radiator end tank and DOHC
models have a plug to the bottom right-hand
side of the radiator.

4Certain SOHC models have a bleed spigot
on the thermostat housing, which is covered
by a rubber cap. The cap should be removed
from the spigot before commencing draining
(see illustration).
5With the expansion tank cap removed,
place a suitable container beneath the
radiator bottom hose or drain plug as
applicable.
6On early models, loosen the clip and ease
the bottom hose away from the radiator
outlet. On later models, unscrew the drain
plug (see illustrations).Allow the coolant to
drain into the container.
7On SOHC models, place a second
container beneath the drain plug on the
right-hand side of the cylinder block (see
illustration).Unscrew the drain plug and
allow the coolant to drain into the container.
No cylinder block drain plug is fitted on CVH
and DOHC models.8Dispose of the drained coolant safely.
9After some time the radiator and engine
waterways may become restricted or even
blocked with scale or sediment, which
reduces the efficiency of the cooling system.
When this occurs, the coolant will appear
rusty and dark in colour and the system
should then be flushed.
10Disconnect the top hose from the radiator,
then insert a garden hose and allow water to
circulate through the radiator until it runs clear
from the outlet.
11Insert the hose in the expansion tank filler
neck and allow water to run out of the bottom
hose (and cylinder block on SOHC models)
until clear. If, after a reasonable period the
water still does not run clear, the radiator can
be flushed with a good proprietary cleaning
agent.
12Disconnect the inlet hose from the inlet
manifold, connect the garden hose and allow
water to circulate through the manifold,
automatic choke (where applicable), heater
and out through the bottom hose until clear.
13In severe cases of contamination the
system should be reverse flushed. To do this,
remove the radiator, invert it and insert a hose
in the outlet. Continue flushing until clear
water runs from the inlet.
14The engine should also be reverse
flushed. To do this, remove the thermostatand insert the hose into the cylinder head on
SOHC models, or into the inlet manifold on
CVH and DOHC models. Continue flushing
until clear water runs from the bottom hose
(and cylinder block on SOHC models).
15Where applicable, refit the radiator and
the thermostat.
16Reconnect any disturbed hoses and refit
and tighten the cylinder block drain plug
and/or radiator drain plug, as applicable.
17On SOHC models fitted with a bleed
spigot on the thermostat housing, ensure that
the rubber cap is removed before refilling the
system.
18Pour coolant in through the expansion
tank filler hole until the level is up to the
“MAX” mark.
19Where applicable, refit the rubber cap to
the bleed spigot when coolant starts to
emerge from the spigot. Tighten the clip.
20Squeeze the coolant hoses to help
disperse air locks. Top-up the coolant further
if necessary, then refit and tighten the
expansion tank cap.
21Run the engine up to operating
temperature, checking for coolant leaks. Stop
the engine and allow it to cool, then re-check
the coolant level. Top-up the level as
necessary, taking care to avoid scalding as
the expansion tank cap is removed.
