1•6Maintenance Procedures
This Chapter is designed to help the home
mechanic maintain his/her vehicle for safety,
economy, long life and peak performance.
The Chapter contains a master maintenance
schedule, followed by Sections dealing
specifically with each task in the schedule.
Visual checks, adjustments, component
renewal and other helpful items are included.
Refer to the accompanying illustrations of the
engine compartment and the underside of the
vehicle for the locations of the various
components.
Servicing your vehicle in accordance with
the mileage/time maintenance schedule and
the following Sections will provide a planned
maintenance programme, which should result
in a long and reliable service life. This is a
comprehensive plan, so maintaining some
items but not others at the specified service
intervals, will not produce the same results.
As you service your vehicle, you will
discover that many of the procedures can -
and should - be grouped together, because of
the particular procedure being performed, or
because of the close proximity of two
otherwise-unrelated components to one
another. For example, if the vehicle is raised
for any reason, the exhaust can be inspected
at the same time as the suspension and
steering components.
The first step in this maintenanceprogramme is to prepare yourself before the
actual work begins. Read through all the
Sections relevant to the work to be carried out,
then make a list and gather together all the
parts and tools required. If a problem is
encountered, seek advice from a parts
specialist, or a dealer service department.
If, from the time the vehicle is new, the
routine maintenance schedule is followed
closely, and frequent checks are made of fluid
levels and high-wear items, as suggested
throughout this manual, the engine will be kept
in relatively good running condition, and the
need for additional work will be minimised.
It is possible that there will be times when
the engine is running poorly due to the lack of
regular maintenance. This is even more likely if
a used vehicle, which has not received regular
and frequent maintenance checks, is
purchased. In such cases, additional work
may need to be carried out, outside of the
regular maintenance intervals.
If engine wear is suspected, a compression
test will provide valuable information regarding
the overall performance of the main internal
components. Such a test can be used as a
basis to decide on the extent of the work to be
carried out. If, for example, a compression test
indicates serious internal engine wear,
conventional maintenance as described in this
Chapter will not greatly improve theperformance of the engine, and may prove a
waste of time and money, unless extensive
overhaul work is carried out first.
The following series of operations are those
most often required to improve the
performance of a generally poor-running
engine:
Primary operations
a)Clean, inspect and test the battery
(Section 6)
b)Check all the engine-related fluids
(Section 3).
c)Check the condition and tension of the
auxiliary drivebelt (Section 21).
d)Renew the spark plugs (Section 20).
e)Inspect the distributor cap, rotor arm and
HT leads - as applicable (Chapter 5).
f)Check the condition of the air cleaner filter
element, and renew if necessary (Section 38).
g)Renew the fuel filter (Section 41).
h)Check the condition of all hoses, and
check for fluid leaks (Section 10).
i)Check the idle speed and mixture settings
- as applicable (Chapter 4).
If the above operations do not prove fully
effective, carry out the following secondary
operations:
Secondary operations
a)Check the charging system (Chapter 5).
b)Check the ignition system (Chapter 5).
c)Check the fuel system (Chapter 4).
d)Renew the distributor cap and rotor arm -
as applicable (Chapter 5).
f)Renew the ignition HT leads - as
applicable (Chapter 5).
2Intensive maintenance
1Introduction
Engine oil
1Check the oil level as follows.
2With the vehicle parked on level ground,
and with the engine having been stopped for a
few minutes, open and prop the bonnet.
Withdraw the dipstick, wipe it on a clean ragand re-insert it fully. Withdraw it again and
read the oil level relative to the marks on the
end of the stick (see illustration).
3The oil level should be in between the MAX
and MIN marks on the dipstick. If it is at or
below the MIN mark, top-up (via the oil filler
cap) without delay. The quantity of oil required
to raise the lever from MIN to MAX on the
dipstick is approximately 1 litre. Do not overfill
(see illustration).
4The rate of oil consumption depends onleaks and on the quantity of oil burnt. External
leakage should be obvious. Oil which is burnt
may enter the combustion chambers through
the valve guides or past the piston rings;
excessive blow-by past the rings can also
force oil out via the crankcase ventilation
system. Driving conditions also affect oil
consumption.
5Always use the correct grade and type of oil
as shown in “Lubricants and fluids”.
Coolant
6Check the coolant level as follows.
7Open and prop the bonnet. Observe the
level of coolant through the translucent walls
of the expansion tank (on the right-hand side
of the engine bay). The level should be up to
the MAX mark when the engine is cold, and
may be somewhat above the mark when hot.
8If topping-up is necessary, wait for the
system to cool down if it is hot. Place a thick
rag over the expansion tank cap and slacken it
3Fluid level checks
3.2 Dipstick markings3.3 Topping up the engine oil
Warning: DO NOT remove the
expansion tank pressure cap
when the engine is hot, as there
is a great risk of scalding.

3Persistent need for topping-up the battery
electrolyte suggests either that the alternator
output is excessive. or that the battery is
approaching the end of its life.
4Further information on the battery, charging
and jump-starting can be found in Chapter 5,
and in the preliminary Sections of this manual.1Clean the wiper blades and the windscreen,
using a solution of concentrated washer fluid
or methylated spirit. Similarly clean the
headlight lens and wiper blades.
2Check the condition of the wiper blades; if
they are cracked or show any signs of
deterioration, or if the glass swept area is
smeared, renew them. At the same time,
check the headlight wiper blades (where fitted)
for condition, and renew if necessary.
3To remove a blade, hinge the arm and blade
away from the screen. Press the tab on the
spring clip in the middle of the blade and
unhook the blade from the arm. 4Refit the blade by sliding it onto the hook on
the arm(see illustration).
5Check that the windscreen washer jets
operate correctly, and direct the washer fluid
towards the upper area of the wiper blade
stroke. If necessary, use a pin to reposition the
washer jets.
7Wiper blade check
1Before starting this procedure, gather
together all the necessary tools and materials.
Also make sure that you have plenty of clean
rags and newspapers handy, to mop up any
spills. Ideally, the engine oil should be warm,
as it will drain better, and more built-up sludge
will be removed with it. Take care, however,
not to touch the exhaust or any other hot parts
of the engine when working under the vehicle.
To avoid any possibility of scalding, and toprotect yourself from possible skin irritants
and other harmful contaminants in used
engine oils, it is advisable to wear gloves when
carrying out this work.
2Access to the underside of the vehicle will be
greatly improved if it can be raised on a lift,
driven onto ramps, or jacked up and supported
on axle stands (see “Jacking”). Whichever
method is chosen, make sure that the vehicle
remains level, or if it is at an angle, that the drain
plug is at the lowest point.
3Slacken the drain plug about half a turn.
Position the draining container under the drain
plug, then remove the plug completely. If
possible, try to keep the plug pressed into the
sump while unscrewing it by hand the last
couple of turns. As the plug releases from the
threads, move it away sharply so the stream of
oil issuing from the sump runs into the
container, not up your sleeve. Recover the
sealing washer from the drain plug.
4Allow some time for the old oil to drain,
noting that it may be necessary to reposition
the container as the oil flow slows to a trickle.
5After all the oil has drained, wipe off the
drain plug with a clean rag. Check the sealing
washer for condition, and renew it if
necessary. Clean the area around the drain
plug opening, and refit the plug. Tighten the
plug to the specified torque.
6Move the container into position under the
oil filter. On SOHC engines, the filter is located
on the left-hand side of the cylinder block in
front of the engine bearer. On DOHC and V6
engines, the filter is located on the right-hand
side of the cylinder block (see illustration).
7Using an oil filter removal tool if necessary,
slacken the filter, then unscrew it by hand the
rest of the way. Empty the oil from the old filter
into the container, and discard the filter.8Use a clean rag to remove all oil, dirt and
sludge from the filter sealing area on the
engine. Check the old filter to make sure that
the rubber sealing ring hasn’t stuck to the
engine. If it has, carefully remove it.
9Apply a light coating of clean engine oil to
the sealing ring on the new filter, then screw it
into position on the engine. Tighten the filter
firmly by hand only - do notuse any tools.
Wipe clean the filter and sump drain plug.
10Remove the old oil and all tools from
under the car, then lower the car to the ground
(if applicable).
11Remove the oil filler cap and withdraw the
dipstick from the top of the filler tube. Fill the
engine, using the correct grade and type of oil
(see “Lubricants and fluids”). An oil can spout
or funnel may help to reduce spillage. Pour in
half the specified quantity of oil first, then wait
a few minutes for the oil to fall to the sump.
Continue adding oil a small quantity at a time
until the level is up to the lower mark on the
dipstick. Finally, bring the level up to the upper
mark on the dipstick. Insert the dipstick, and
refit the filler cap.
12Start the engine and run it for a few
minutes; check for leaks around the oil filter
seal and the sump drain plug. Note that there
may be a delay of a few seconds before the oil
pressure warning light goes out when the
engine is first started, as the oil circulates
through the engine oil galleries and the new oil
filter, before the pressure builds up.
13Switch off the engine, and wait a few
minutes for the oil to settle in the sump once
more. With the new oil circulated and the filter
completely full, recheck the level on the
dipstick, and add more oil as necessary.
14Dispose of the used engine oil safely, with
reference to “General repair procedures”in the
reference Sections of this manual.

For maximum clarity of vision,
windscreen wiper blades
should be renewed annually,
as a matter of course.
Frequent oil and filter changes
are the most important
preventative maintenance
procedures which can be
undertaken by the DIY owner. As
engine oil ages, it becomes diluted and
contaminated, which leads to
premature engine wear.

DOHC engines
12On this engine, the coolant/alternator
drivebelt also drives the power steering pump
and (where applicable) the air conditioning
compressor. The drivebelt tension is set by an
automatic tensioner assembly.
13The condition of the drivebelt should be
checked as described above.
14An idea of the amount of wear which has
taken place on the belt can be gained from the
position of indicator mark (A) on the mounting
bracket in relation to the block (B) on the
tensioner arm (see illustration).When the belt
is new the mark should be aligned with the top
of the tensioner block. As the belt wears, the
tensioner arm moves and the block on the arm
will move slowly up in relation to the mark on
the bracket. When the mark aligns with the
bottom of the tensioner arm block the belt can
be regarded as worn and should be replaced
(see illustration).
15To renew the belt, turn the automatic
tensioner arm clockwise, using a 17 mm
socket and a wrench on the boss in the centre
of the pulley, and slide the belt from the
pulleys, then slowly release the tensioner.
16To fit a new belt, rotate the tensioner
clockwise as during removal, then slide the
belt over the pulleys. With the belt correctly
located, slowly release the tensioner; the
tensioner will automatically set the correct
drivebelt tension.
Caution:Before carrying out any work on the
vehicle battery, read through the precautions
given in “Safety first!” at the beginning of this
manual.
1The battery fitted as original equipment is
“maintenance-free”, and requires no
maintenance 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.
Periodically inspect the battery tray for
corrosion, and make good as necessary.
5Further information on the battery, charging
and jump-starting can be found in Chapter 5,
and in the preliminary Sections of this manual.
SOHC engines
1Valve clearances are checked with the
engine cold.
2On carburettor models, remove the air cleaner.
3On fuel-injection models, remove the
bracing strap which connects the inlet
manifold to the right-hand side of the engine.
4On all models, identify the HT leads and
disconnect them from the spark plugs. Unclip
the leads from the rocker cover.
5Although not essential, it will make the
engine easier to turn if the spark plugs are
removed.
6Remove the ten bolts which secure the
rocker cover, noting the location of the
different shapes of reinforcing plates. Remove
the cover and gasket.7One of the cam lobes will be seen to be
pointing upwards. Measure the clearance
between the base of this cam and the cam
follower, finding the thickness of feeler blade
which gives a firm sliding fit(see illustration).
8The desired valve clearances are given in
the Specifications. Note that the clearances
for inlet and exhaust valves are different.
Numbering from the front (sprocket) end of the
camshaft, the exhaust valves are 1, 3, 5 and 7,
and the inlet valves 2, 4, 6 and 8.
9If adjustment is necessary, slacken the ball-
pin locknut and screw the ball-pin up or down
until the clearance is correct. Hold the ball-pin
stationary and tighten the locknut(see
illustration).Recheck the clearance after
tightening the locknut in case the ball-pin has
moved.
10Turn the engine to bring another cam lobe
to the vertical position and repeat the above
procedure. Carry on until all eight valves have
been checked.
11Access to some of the ball-pins is made
difficult by the carburettor or fuel-injection inlet
manifold. To avoid having to remove the
offending components, double cranked
spanners or cutaway socket spanners can be
used (see illustration).
12When adjustment is complete, refit the
rocker cover using a new gasket. Make sure
that the dovetail sections of the gasket fit
together correctly.
13Fit the rocker cover bolts and reinforcing
plates. Tighten the bolts as described in
Chapter 2A Section 44, paragraph 11.

1Remove the radiator grille being careful not
to damage the condenser fins.
2Check the refrigerant charge as follows. The
engine should be cold and the ambient
temperature should be between 18°and 25°C
(64°and 77°F).
3Start the engine and allow it to idle. Observe
the refrigerant sight glass(see illustration)
and have an assistant switch on the air
conditioning to fan speed III. A few bubbles
should be seen in the sight glass as the
system starts up, but all bubbles should
disappear within 10 seconds. Persistent
bubbles, or no bubbles at all, mean that the
refrigerant charge is low. Switch off the
system immediately if the charge is low and do
not use it again until it has been recharged.
4Inspect the refrigerant pipes, hoses and
unions for security and good condition. Refit
the radiator grille.
5The air conditioning system will lose a
proportion of its charge through normal
seepage typically up to 100 g (4 oz) per year -
so it is as well to regard periodic recharging as
a maintenance operation.
1Check the final drive oil level as follows.
2Position the vehicle over a pit, or raise it at
front and rear on ramps or axle stands (see
“Jacking”). The vehicle must be level.
3Wipe clean around the final drive filler/level
plug (see illustration).Unscrew the plug with
a hexagon key. Using a piece of bent wire as
a dipstick, check that the oil is no more than
10 mm (0.4 in) below the plug hole.
4If topping-up is necessary, use clean gear
oil of the specified type. Do not overfill.
Frequent need for topping-up can only be due
to leaks, which should be rectified.
5When the level is correct, refit the filler/level
plug and tighten it.
6There is no requirement for periodic oil
changing, and no drain plug is provided. Lubricate the transmission selector and
kickdown linkages with engine oil or aerosol
lubricant.
1Examine all steering and suspension
components for wear and damage. Pay
particular attention to dust covers and gaiters,
which if renewed promptly when damaged can
save further damage to the component
protected.
2At the same intervals, check the front
suspension lower arm balljoints for wear by
levering up the arms(see illustration).
Balljoint free movement must not exceed
0.5 mm (0.02 in). The track rod end balljoints
can be checked in a similar manner, or by
observing them whilst an assistant rocks the
steering wheel back and forth. If the lower arm
balljoint is worn, the complete lower arm must
be renewed.
3Check the shock absorbers by bouncing the
vehicle up and down at each corner in turn.
When released, it should come to rest within
one complete oscillation. Continued
movement, or squeaking and groaning noises
from the shock absorber suggests that
renewal is required.Position the vehicle over a pit, or raise it at
front and rear on ramps or axle stands.
Examine the driveshaft joint rubber gaiters.
Flex the gaiters by hand and inspect the folds
and clips. Damaged or leaking gaiters must be
renewed without delay to avoid damage
occurring to the joint itself
Check the tightness of the final drive
mounting bolts and the driveshaft flange
screws.
1Except on vehicles with a wax-based
underbody protective coating, have the whole
of the underframe of the vehicle steam-
cleaned, engine compartment included, so
that a thorough inspection can be carried out
to see what minor repairs and renovations are
necessary.
2Steam-cleaning is available at many
garages, and is necessary for the removal of
the accumulation of oily grime, which
sometimes is allowed to become thick in
certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-applied;
the dirt can then be simply hosed off.
3After cleaning, position the vehicle over a
pit, or raise it at front and rear on ramps or axle
stands.
4Using a strong light, work around the
underside of the vehicle, inspecting it for
corrosion or damage. If either is found, refer to
Chapter 12 for details of repair.
Periodically inspect the rigid brake pipes for
rust and other damage, and the flexible hoses
for cracks, splits or “ballooning”. Have an
assistant depress the brake pedal (ignition on)
and inspect the hose and pipe unions for
leaks. Renew any defective item without delay.
On 2.0 litre engines, good electrical contact
between the carburettor stepper motor
plunger and the adjusting screw is essential to
maintain a regular idle speed.
Clean the plunger and adjusting screw
contact faces with abrasive paper followed by
switch cleaning fluid. Switch cleaning fluid is
available from electronic component shops.

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.

hoses on the engine compartment bulkhead.
Slacken the retaining clips and disconnect
both hoses from the matrix unions. Be
prepared for some coolant spillage. Plug the
matrix unions to prevent residual coolant
being spilt as the assembly is removed.
17Slacken and remove the two retaining
screws then remove the matrix cover plate
and gasket from the bulkhead; discard the
gasket as a new one should be used on
refitting.
18Remove the facia panel.
19Release the facia wiring loom from the
bulkhead to gain access to the demister
nozzle fasteners (see illustration).
20Remove the retaining nut and screw then
detach each windscreen demister nozzle from
the heater assembly. Undo the two retaining
nuts and detach the centre face level nozzle
from the heater.
21Slacken and remove the two retaining nuts
then detach the right-hand face level nozzle
from the heater and remove it from the vehicle.
Repeat the procedure for the left-hand nozzle.
22To detach each rear footwell nozzle from
the heater unit, remove the pin from the nozzle
retaining clip whilst supporting the outer part
of the retaining clip from the rear (see
illustration). Note: If the rear of the clip is not
supported when the pin is removed it will drop
down into the nozzle. To retrieve the clip will
require the removal of the vent which first
requires the front seat to be removed and
carpet lifted.
23Disconnect the wiring connector from the
heater control panel.
24Undo the two nuts securing the heater
assembly to the bulkhead then carefully
manoeuvre the assembly out of the vehicle
whilst being prepared for the possibility of
coolant spillage from the matrix unions.
25Refitting is a reverse of the removal
procedure noting the following points.
a)Tighten all retaining nuts and screws
securely and ensure that all nozzles are
securely connected to the heater
assembly so that there are no air gaps or
leaks.b)Check the operation of all heater cables
before refitting the facia, ensuring that the
relevant component moves smoothly from
the fully open to the fully closed position.
c)Ensure that the heater hoses are correctly
reconnected and are securely held by the
retaining clips.
d)Use a new gasket when refitting the matrix
cover plate.
e)Refill the cooling system.
1Remove the heater assembly as described
in the previous Section.
2Remove the two screws which secure the
heater matrix. Withdraw the matrix.
3If the matrix is leaking it is best to obtain a
new or reconditioned unit; home repairs are
seldom successful.4To dismantle, release the clips which secure
the casing halves together by using a
screwdriver. Carefully prise the halves apart
and separate them.
5Remove the flap valves and operating levers
from the casing halves, noting how they are
fitted for reference when reassembling.
6Flush the matrix with clean water to remove
any debris.
7Reassembly is a reversal of dismantling.
Additional clips may be needed to secure the
casing halves once they have been separated.
1Drain the cooling system.
2Noting the correct fitted positions, slacken
the retaining clips and disconnect the coolant
hoses from the valve.
3Disconnect the vacuum pipe from the top of
the valve then unclip the valve and remove it
from the retaining bracket.
4Refitting is a reverse of the removal
procedure ensuring that the coolant hoses are
reconnected to their original unions on the
valve and are securely held in position with the
retaining clips.
1Only those items which can be renewed
without discharging the system are described
here. Other items must be dealt with by a Ford
dealer or air conditioning specialist (see
illustration).

engine coolant temperature sensor. The
crankshaft speed/position sensor is activated
by a toothed disc on the rear of the crankshaft,
inside the cylinder block. The disc has 35
equally spaced teeth (one every 10°), with a
gap in the 36th position. The gap is used by
the sensor to determine the crankshaft
position relative to Top Dead Centre (TDC) of
No 1 piston.
The ignition advance is a function of the
ESC II module, and is controlled by vacuum.
The module is connected to the carburettor by
a vacuum pipe, and a transducer in the
module translates the vacuum signal into an
electrical voltage. From the vacuum signal, the
module determines engine load; engine speed
and temperature are determined from the
crankshaft speed/position sensor and the
engine coolant temperature sensor. The
module has a range of spark advance settings
stored in the memory, and a suitable setting is
selected for the relevant engine speed, load
and temperature. The degree of advance can
thus be constantly varied to suit the prevailing
engine speed and load conditions.
On DOHC fuel-injected engines, a
development of the EEC IV (Electronic Engine
Control IV) engine management system is
used to control both the ignition and fuel-
injection systems. The EEC IV module receives
information from a crankshaft speed/position
sensor (the same as that fitted to the
carburettor models), a throttle position sensor,
an engine coolant temperature sensor, a fuel
temperature sensor, an air charge temperature
sensor, a Manifold Absolute Pressure (MAP)
sensor, and a vehicle speed sensor (mounted
on the gearbox). Additionally, on models with
a catalytic converter, an additional input is
supplied to the EEC IV module from an
exhaust gas oxygen (HEGO) sensor. On
models with automatic transmission,
additional sensors are fitted to the
transmission to inform the EEC IV module
when the transmission is in neutral, and when
the downshift is being operated.
The module provides outputs to control the
fuel pump, fuel-injectors, idle speed, ignition
system and automatic transmission .
Additionally, on models with air conditioning,
the EEC IV module disengages the air
conditioning compressor clutch when starting
the engine or when the engine is suddenly
accelerated. On models fitted with a catalytic
converter, the EEC IV module also controls the
carbon canister purge solenoid valve.
Using the inputs from the various sensors,
the EEC IV module computes the optimum
ignition advance, and fuel-injector pulse
duration to suit the prevailing engine
conditions.
On 2.4 & 2.9 litre V6 engines, the system
operates in much the same way as that fitted
to the DOHC fuel-injected engine, noting the
following points.
a)There is no crankshaft speed/position
sensor.
b)The vehicle speed sensor is only fitted to
models equipped with a catalytic
converter.Precautions
ESC II module
Although it will tolerate all normal under-
bonnet conditions, the ESC II module may be
adversely affected by water entry during
steam cleaning or pressure washing of the
engine bay.
If cleaning the engine bay, therefore, take
care not to direct jets of water or steam at the
ESC II module. If this cannot be avoided,
remove the module completely, and protect its
multi-plug with a plastic bag.
Ignition system HT voltage
Take care to avoid receiving electric shocks
from the HT side of the ignition system. Do not
handle HT leads, or touch the distributor or
coil, when the engine is running. When tracing
faults in the HT system, use well insulated
tools to manipulate live leads. Electronic
ignition HT voltage could prove fatal.
Electronic ignition systems
General
Further details of the various systems are
given in the relevant Sections of this Chapter.
While some repair procedures are given, the
usual course of action is to renew the
component concerned. The owner whose
interest extends beyond mere component
renewal should obtain a copy of the
Automobile Electrical & Electronic Systems
Manual, available from the publishers of this
manual.
It is necessary to take extra care when
working on the electrical system, to avoid
damage to semi-conductor devices (diodes
and transistors), and to avoid the risk of
personal injury. In addition to the precautions
given in Safety first!at the beginning of this
manual, observe the following when working
on the system:
Always remove rings, watches, etc before
working on the electrical system.Even with the
battery disconnected, capacitive discharge
could occur if a component’s live terminal is
earthed through a metal object. This could
cause a shock or nasty burn.
Do not reverse the battery connections.
Components such as the alternator, electronic
control units, or any other components having
semi-conductor circuitry, could be irreparably
damaged.
If the engine is being started using jump
leads and a slave battery, connect thebatteries positive-to-positiveand negative-to-
negative(see “Jump starting”). This also
applies when connecting a battery charger.
Never disconnect the battery terminals, the
alternator, any electrical wiring, or any test
instruments, when the engine is running.
Do not allow the engine to turn the alternator
when the alternator is not connected.
Never test for alternator output by “flashing”
the output lead to earth.
Never use an ohmmeter of the type
incorporating a hand-cranked generator for
circuit or continuity testing.
Always ensure that the battery negative lead
is disconnected when working on the
electrical system.
Before using electric-arc welding equipment
on the car, disconnect the battery, alternator,
and components such as the fuel-
injection/ignition electronic control unit, to
protect them from the risk of damage.
Refer to Chapter 13
1In normal use the battery should not require
charging from an external source, unless the
vehicle is laid up for long periods, when it
should be recharged every six weeks or so. If
vehicle use consists entirely of short runs in
darkness it is also possible for the battery to
become discharged. Otherwise, a regular
need for recharging points to a fault in the
battery or elsewhere in the charging system.
2There is no need to disconnect the battery
from the vehicle wiring when using a battery
charger, but switch off the ignition and leave
the bonnet open.
3Domestic battery chargers (up to about 6
amps output) may safely be used overnight
without special precautions. Make sure that
the charger is set to deliver 12 volts before
connecting it. Connect the leads (red or
positive to the positive terminal, black or
negative to the negative terminal) before
switching the charger on at the mains.
4When charging is complete, switch off at
the mains beforedisconnecting the charger
from the battery. Remember that the battery
will be giving off hydrogen gas, which is
potentially explosive.
5Charging at a higher rate should only be
carried out under carefully controlled
conditions. Very rapid or “boost” charging
should be avoided if possible, as it is liable to
cause permanent damage to the battery
through overheating.
6During any sort of charging, battery
electrolyte temperature should never exceed
38°C (100°F). If the battery becomes hot, or
the electrolyte is effervescing vigorously,
charging should be stopped.

Warning. The voltages produced
by the electronic ignition system
are considerably higher than those
produced by conventional
systems. Extreme care must be taken when
working on the system with the ignition
switched on. Persons with surgically-
implanted cardiac pacemaker devices
should keep well clear of the ignition
circuits, components and test equipment.

1Disconnect the battery negative (earth) lead.
2Disconnect the battery positive leads. These
may be protected by a plastic cover. Do not
allow the spanner to bridge the positive and
negative terminals.
3Release the battery hold-down clamp. Lift
out the battery. Keep it upright and be careful
not to drop it - it is heavy.
4Commence by placing the battery in its tray,
making sure it is the right way round. Secure it
with the hold-down clamp.
5Clean the battery terminals if necessary
then reconnect them. Connect the positive
lead first, then the negative lead.
1Should it appear that the alternator is not
charging the battery, check first that the
drivebelt is intact and in good condition and
that its tension is correct. Also check the
condition and security of the alternator
electrical connections and the battery leads.
2Accurate assessment of alternator output
requires special equipment and a degree of
skill. A rough idea of whether output is
adequate can be gained by using a voltmeter
(range 0 to 15 or 0 to 20 volts) as follows.
3Connect the voltmeter across the battery
terminals. Switch on the headlights and note
the voltage reading: it should be between 12
and 13 volts.
4Start the engine and run it at a fast idle
(approx 1500 rpm). Read the voltmeter: it
should indicate 13 to 14 volts.
5With the engine still running at a fast idle,
switch on as many electrical consumers as
possible (heated rear window, heater blower
etc). The voltage at the battery should be
maintained at 13 to 14 volts. Increase the
engine speed slightly if necessary to keep the
voltage up.
6If alternator output is low or zero, check the
brushes. If the brushes are OK, seek expert
advice.7Occasionally the condition may arise where
the alternator output is excessive. Clues to this
condition are constantly blowing bulbs;
brightness of lights vary considerably with
engine speed; overheating of alternator and
battery, possible with steam or fumes coming
from the battery. This condition is almost
certainly due to a defective voltage regulator,
but expert advice should be sought.
8Note that the alternator voltage regulator
can be renewed without removing the
alternator from the vehicle. The procedure is
part of brush renewal.
1Disconnect the battery negative lead.
2Disconnect the multi-plug from the rear of
the alternator. It may be secured by a wire clip.
3Slacken the alternator adjusting and pivot
nut(s), bolt(s)and washer(s)(see illustration).
Swing the alternator towards the engine and
slip the drivebelt(s) off the pulley.
4Support the alternator. Remove the
adjusting and pivot nuts, bolts and washers,
noting the fitted positions of the washers. Lift
out the alternator. Do not drop it, it is fragile.
5Refit by reversing the removal operations.
Tension the drivebelt(s) then tighten the
adjustment strap bolt followed by the pivot nut
and bolt. If there are two pivot bolts, tighten
the front one first.
6Refit the multi-plug and reconnect the
battery.
1The alternator brushes can be inspected or
renewed without removing the alternator from
the vehicle, but disconnect the battery
negative lead first.
2From the rear of the alternator remove the
two screws which secure the voltage
regulator/brush carrier assembly. Withdraw
the assembly (see illustration).
3Measure the length of each brush
protruding from the carrier (see illustration). If
they are worn down to, or below, the minimumspecified, the old brushes will have to be
unsoldered and new ones soldered into place.
Some skill with a soldering iron will be
required; excess heat from the soldering iron
could damage the voltage regulator. When
fitted, the new brushes must move freely in
their holders.
4Clean the slip rings with a cloth moistened
with methylated spirit (see illustration). If they
are badly burnt or damaged, seek expert
advice.
5Refit the assembled brush carrier/voltage
regulator and secure it with the two screws. If
the alternator is on the vehicle, reconnect the
battery negative lead.
1If the starter motor fails to operate, first
check that the battery is charged by switching
on the headlights. If the headlights do not
come on, or rapidly become dim, the battery
or its connections are at fault.
2Check the security and condition of the
battery and starter solenoid connections.
Remember that the heavy lead to the solenoid
is always “live” - disconnect the battery
negative lead before using tools on the
solenoid connections.
