27Refitting is a reversal of removal, ensuring
that the rotor arm is pushed fully home on the
rotor shaft. Make sure that the HT leads are
fitted to their correct cylinders. Note that the
rotor arm will only fit in one position.
Note: A brake band torque wrench - Ford tool
No 17-005, or equivalent - will be required for
this job.
1Raise and support the front of the vehicle.
2Disconnect the downshift (kickdown) cable
from the transmission when so equipped.
3Release the locknuts on the two brake band
adjuster screws. Back off each adjuster screw
a couple of turns (see illustration).
4Using the torque wrench, tighten one
adjusting screw to 13 Nm (10 lbf ft). Remove
the torque wrench and back off the adjuster
screw exactly two full turns from this position,
then hold the screw and tighten the locknut.
5Repeat the operations on the other adjuster.
6Reconnect the downshift cable, when
applicable, then lower the vehicle.
OHC engines
1Fitted to all fuel-injected models, the filter
can be renewed as follows. Disconnect the
battery negative lead.
2Raise and support the rear of the vehicle.
3Place a drain pan under the fuel filter. Take
adequate fire precautions.
4Wipe clean the area around the filter inlet
and outlet unions, then disconnect them (see
illustration). Caution: Fuel under pressure
may spray out as the unions are slackened.
5Slacken the filter clamp bolt and withdraw
the filter from the clamp. Dispose of the filter
safely, remember it is full of fuel.
6Fit the new filter into the clamp,observing
the arrows on the filter indicating the direction
of fuel flow. If there is a plastic band or sleeve
on the filter, position the clamp over the sleeve
to prevent chafing. Tighten the clamp bolt.
7Refit the inlet and outlet unions, using new
sealing washers. Tighten the union bolts.
8Reconnect the battery. Have an assistantswitch the ignition on and off a few times to
pressurise the system; watch the filter for
leakage as this is done.
9Lower the vehicle on completion.
V6 engines
10This operation is essentially the same as
described above, noting that the fuel system
should first be depressurised, see Chapter 4,
Section 28.
11Once the new filter has been installed,
switch the ignition on and off five times,
without cranking the engine, to pressurise the
system then check the filter unions for leaks.
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.
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.

(nearly half a gallon).2Slacken the front wheel nuts. Raise and
support the front of the vehicle andremove
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 thepiston 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.

locations when mating the engine to the
gearbox. If the engine has been overhauled,
where applicable fit the relevant shims as
calculated during engine reassembly.
6Ensure that the roadwheels and the steering
wheel are in the straight-ahead position then
align the marks made on removal and
reconnect the intermediate shaft to the
steering gearing. Tighten the clamp bolt to the
specified torque.
7Reconnect the clutch cable to the release
arm, ensuring that it is routed as noted during
removal.
8Refit the propeller shaft.
9Refit the exhaust system.
10Fill the engine with the correct grade and
quantity of oil.
11Check the throttle cable adjustment. Where
necessary, also adjust the speed control cable
in the same way so that there is only a small
amount of slack present in the cable.
12Reconnect the coolant hoses to the water
pump housing.
13Fill the cooling system.
14Check and if necessary top-up the
gearbox oil level.
15Tighten all fixings to the specified torque,
where applicable.
1Reverse the procedure described in Section 8,
noting the following points.
2Check that the engine adapter plate is
correctly positioned on the locating dowels. If
necessary, a cable-tie can be used to
temporarily secure the adapter plate in
position on the cylinder block using one of the
engine-to-transmission bolt holes.
3As the torque converter is only loosely
engaged in the transmission, care must be taken
to prevent the torque converter from falling out
forwards. When the torque converter hub is fully
engaged with the fluid pump drivegear in the
transmission, distance A (see illustration 2.20 in
Chapter 7B)must be as specified. Incorrect
installation of the torque converter will result in
damage to the transmission.
4If shims were fitted between the sump and
the transmission, refit them in their original
locations when mating the engine to the
transmission. If the engine has been
overhauled, where applicable fit the relevant
shims as calculated during engine reassembly.

Cooling system
The cooling system is of pressurised type
and includes a front mounted crossflow
radiator, belt-driven water pump, temperature-
sensitive thermo-viscous fan (on DOHC
models, an electrically-operated cooling fan is
fitted, operated by a switch in the thermostat
housing), wax type thermostat, and an
expansion and degas tank.
The radiator matrix is of copper and brass
construction and the end tanks are of plastic.
On automatic transmission models the right-
hand side end tank incorporates the
transmission oil cooler.
The thermostat is located behind the water
outlet elbow at the front of the cylinder head
on OHCmodels, and on the front of the water
pump on V6 models. Its purpose is to ensure
rapid engine warm-up by restricting the flow of
coolant in the engine when cold, and also to
assist in regulating the normal operating
temperature of the engine.
The expansion tank incorporates a pressure
cap which effectively pressurises the cooling
system as the coolant temperature rises,
thereby increasing the boiling point of the
coolant. The tank also has a further degas
function. Any accumulation of air bubbles in
the coolant, in particular in the thermostat
housing and the radiator, is returned to the
tank and released in the air space thus
maintaining the efficiency of the coolant.
On models fitted with the auxiliary warning
system, the expansion tank contains a level
sensor which operates a warning light if the
coolant level falls significantly.
When the engine is started from cold, the
water pump circulates coolant around the
cylinder block, cylinder head(s) and inlet
manifold. The warm coolant passes through
the automatic choke housing (when
applicable) and through the heater matrix
before returning to the engine. As the coolant
expands, the level in the expansion tank rises.
Circulation of coolant through the radiator is
prevented while the thermostat is shut. When
the coolant reaches the predeterminedtemperature the thermostat opens and hot
water passes through the top hose to the top
of the radiator. As the water circulates down
through the radiator, it is cooled by the
passage of air past the radiator when the car is
in forward motion, supplemented by the action
of the thermo-viscous fan when necessary.
Having reached the bottom of the radiator, the
water is now cool and the cycle is repeated.
Circulation of water continues through the
expansion tank, inlet manifold and heater at all
times; the heater temperature control being by
an air flap.
The thermo-viscous fan is controlled by the
temperature of air behind the radiator. When
the air temperature reaches a predetermined
level, a bi-metallic coil commences to open a
valve within the unit and silicon fluid is fed
through a system of vanes. Half of the vanes
are driven directly by the water pump and the
remaining half are connected to the fan blades.
The vanes are arranged so that drive is
transmitted to the fan blades in relation to the
drag or viscosity of the fluid, and this in turn
depends on ambient temperature and engine
speed. The fan is therefore only operated when
required, and compared with direct drive type
fan represents a considerable improvement in
fuel economy, drivebelt wear and fan noise.
Air conditioning
Air conditioning is fitted as standard on
Scorpio models and is optionally available on
some other models. In conjunction with the
heater, the system enables any reasonable air
temperature to be achieved inside the car, it
also reduces the humidity of the incoming air,
aiding demisting even when cooling is not
required.
The refrigeration side of the air conditioning
system functions in a similar way to a
domestic refrigerator. A compressor, belt-
driven from the crankshaft pulley, draws
refrigerant in its gaseous phase from an
evaporator. The compressed refrigerant
passes through a condenser where it loses
heat and enters its liquid phase. After
dehydration the refrigerant returns to the
evaporator where it absorbs heat from air
passing over the evaporator fins. The
refrigerant becomes a gas again and the cycle
is repeated.Various subsidiary controls and sensors
protect the system against excessive
temperature and pressures. Additionally,
engine idle speed is increased when the
system is in use to compensate for the
additional load imposed by the compressor.
Precautions
Antifreeze mixture
Antifreeze mixture is poisonous. Keep it out
of reach of children and pets. Wash splashes
off skin and clothing with plenty of water.
Wash splashes off vehicle paintwork to avoid
discolouration.
Antifreeze/water mixture must be renewed
every two years to preserve its anti-corrosive
properties. In climates where antifreeze
protection is unnecessary, a corrosion
inhibitor may be used instead - consult a Ford
dealer. Never run the engine for long periods
with plain water as coolant. Only use the
specified antifreeze, as inferior brands may not
contain the necessary corrosion inhibitors, or
may break down at high temperatures.
Antifreeze containing methanol is particularly
to be avoided, as the methanol evaporates.
The specified mixture is 45 to 50%
antifreeze and 50 to 55% clean soft water (by
volume). Mix the required quantity in a clean
container.
Air conditioning refrigerant
Although the refrigerant is not itself toxic, in
the presence of a naked flame (or a lighted
cigarette) it forms a highly toxic gas. Liquid
refrigerant spilled on the skin will cause
frostbite. If refrigerant enters the eyes, rinse
them with a dilute solution of boric acid and
seek medical advice immediately.
In view of the above points, and of the need
for specialised equipment for evacuating and
recharging the system, any work which
requires the disconnection of a refrigerant line
must be left to a specialist.
Do not allow refrigerant lines to be exposed
to temperatures above 110°C (230°F) - eg
during welding or paint drying operations and
do not operate the air conditioning system if it
is known to be short of refrigerant, or further
damage may result.

1Drain the radiator. There is no need to drain
the cylinder block. On DOHC engines the
electric cooling fan assembly must be removed
to gain the clearance to remove the radiator.
2Disconnect the top and bottom hoses from
the radiator by slackening the hose clips and
pulling off the hoses with a twisting motion
(see illustrations). Do not use excessive force
- the radiator side tanks are made of plastic.
3On OHCmodels, disconnect the small hose
running from the expansion tank to the radiator.
4On automatic transmission models, clean
around the transmission fluid cooler unions on
the radiator and disconnect them (seeillustration). Be prepared for fluid spillage;
plug or cap the cooler lines to keep dirt out.
5On models with air conditioning, disconnect
the auxiliary fan thermo-switch. If the thermo-
switch is mounted in the radiator, remove It.
6Remove the upper half of the fan shroud by
removing the two bolts and two clips (see
illustration), and the lower half which is
secured by two bolts.
7Release the two radiator top mounting clips
by pulling out the plastic plugs (see illustration).
8Raise and support the front of the vehicle.
Support the radiator and remove the two
bottom mounting bolts (see illustration).
9Carefully lower the radiator slightly to free
the top mountings, then remove it from under
the vehicle.
10If a new radiator is being fitted, transfer the
fan shrouds and mountings from the old one.
11Refit by reversing the removal operations,
then refill the cooling system.
12On automatic transmission models, check
the transmission fluid level.
1If the radiator has been removed because of
suspected blockage, reverse-flush it.
2Clean dirt and debris from the radiator fins,
using an air jet, or water and a soft brush. Be
careful not to damage the fins, or cut your
fingers. 3A radiator specialist can perform a “flow
test” on the radiator to establish whether an
internal blockage exists.
4A leaking radiator must be referred to a
specialist for permanent repair. Do not attempt
to weld or solder a leaking radiator, as
damage to the plastic parts may result.
5In an emergency, minor leaks from the
radiator can be cured by using a radiator
sealant while the radiator is in situ.
SOHC engines
1Disconnect the battery negative lead.
2Drain the cooling system. As it is not
necessary to completely drain the radiator, the
bottom hose can be disconnected from the
water pump.
3Disconnect the top hose from the
thermostat housing at the front of the cylinder
head (see illustration).
4Unscrew the bolts and remove the housing
and gasket (see illustration).
5Using a screwdriver, prise the retaining clip
from the housing, and extract the thermostat
and sealing ring (see illustrations).
6Clean the thermostat housing and cylinder
head mating surfaces. Obtain a new gasket for
reassembly, and if necessary a new sealing
ring too.
7Refit by reversing the removal operations.

16Undo the wiring connector retaining bolt
then carefully disconnect the wiring plug and
remove the module from the car (see
illustration).
17Refitting is a reverse of the removal
procedure ensuring that the wiring plug bolt is
securely tightened. On completion start the
engine and check that it runs correctly.
Note: Irregular idle is not necessarily caused
by a faulty or badly adjusted stepper motor.
Good electrical contact between the stepper
motor plunger and the adjusting screw is
essential. Before attempting adjustment or
renewal of the motor, try the effect of cleaning
the plunger and adjusting screw contact faces
with abrasive paper followed by switch
cleaning fluid. Switch cleaning fluid is available
from electronic component shops.
1Disconnect the battery negative lead.
2Remove the air cleaner.
3Disconnect the multi-plug from the stepper
motor. Release the locking clip and pull on the
plug, not on the wires.
4Remove the four screws which secure the
stepper motor bracket to the carburettor.Remove the motor and bracket and separate
them (see illustration).
5Refit the motor and bracket to the
carburettor and secure with the four screws.
Reconnect the multi-plug.
6Make an initial adjustment to the throttle
lever adjusting screw if necessary so that it
protrudes from the lever by dimension X (see
illustration).
7Reconnect the air cleaner vacuum hose.
Position the air cleaner to one side so that
there is still access to the carburettor and
stepper motor.
8Connect a tachometer (rev. counter) to the
engine as instructed by the manufacturers.
Reconnect the battery.
9Run the engine. Check the idle mixture (CO
level) as described in Chapter 4 and adjust if
necessary.
10Switch off all electrical loads (headlights,
heater blower etc). If the idle speed adjustment
lead is earthed, temporarily isolate it. Make
sure that the automatic transmission selector is
in the N or P position (where applicable).
11Accelerate the engine to a speed greater
then 2500 rpm, allow it to return to idle, then
repeat. Insert a feeler blade of thickness 1.0
mm (0.04 in) between the stepper motor
plunger and the adjusting screw(see
illustration).With the feeler blade in place,
engine speed should be 875 ±25 rpm. 12If adjustment is necessary, remove the
tamperproof cap from the adjusting screw
locknut. Release the locknut, turn the
adjusting screw to achieve the correct speed
and tighten the locknut.
13Repeat paragraph 11 and check that the
speed is still correct. Readjust if necessary.
14Remove the feeler blade. Stop and restart
the engine, observing the stepper motor
plunger. Immediately after switching off, the
plunger should move to the “anti-dieseling”
position; after a few seconds it should extend
to the “vent manifold/start” position (see
illustration).
15Disconnect the test gear and refit the air
cleaner.
16Recheck the idle mixture.
17Fit new tamperproof plugs or caps if
necessary - see Chapter 4,
18Reconnect the idle speed adjustment lead
if it was earthed.

temperature sensor is located on the underside
of the inlet manifold (SOHC engines), the side
of the manifold (DOHC engines) or on the front
face of the cylinder block (V6 engines).
