1993 FORD MONDEO lights

Working on your car can be dangerous.
This page shows just some of the potential
risks and hazards, with the aim of creating a
safety-conscious attitude.
General hazards
Scalding
• Don’t remove the radiator or expansion
tank cap while the engine is hot.
• Engine oil, automatic transmission fluid or
power steering fluid may also be dangerously
hot if the engine has recently been running.
Burning
• Beware of burns from the exhaust system
and from any part of the engine. Brake discs
and drums can also be extremely hot
immediately after use.
Crushing
• When working under or near
a raised vehicle, always
supplement the
jack with axle
stands, or use
drive-on ramps.
Never venture
under a car
which is only
supported by
a jack.
• Take care if loosening or tightening high-
torque nuts when the vehicle is on stands.
Initial loosening and final tightening should
be done with the wheels on the ground.
Fire
• Fuel is highly flammable; fuel vapour is
explosive.
• Don’t let fuel spill onto a hot engine.
• Do not smoke or allow naked lights
(including pilot lights) anywhere near a
vehicle being worked on. Also beware of
creating sparks
(electrically or by use of tools).
• Fuel vapour is heavier than air, so don’t
work on the fuel system with the vehicle over
an inspection pit.
• Another cause of fire is an electrical
overload or short-circuit. Take care when
repairing or modifying the vehicle wiring.
• Keep a fire extinguisher handy, of a type
suitable for use on fuel and electrical fires.
Electric shock
• Ignition HT
voltage can be
dangerous,
especially to
people with
heart problems
or a pacemaker.
Don’t work on or
near the ignition
system with the
engine running or the
ignition switched on.• Mains voltage is also dangerous. Make
sure that any mains-operated equipment is
correctly earthed. Mains power points should
be protected by a residual current device
(RCD) circuit breaker.
Fume or gas intoxication
• Exhaust fumes are
poisonous; they often
contain carbon
monoxide, which is
rapidly fatal if inhaled.
Never run the
engine in a
confined space
such as a garage
with the doors shut.
• Fuel vapour is also
poisonous, as are the vapours from some
cleaning solvents and paint thinners.
Poisonous or irritant substances
• Avoid skin contact with battery acid and
with any fuel, fluid or lubricant, especially
antifreeze, brake hydraulic fluid and Diesel
fuel. Don’t syphon them by mouth. If such a
substance is swallowed or gets into the eyes,
seek medical advice.
• Prolonged contact with used engine oil can
cause skin cancer. Wear gloves or use a
barrier cream if necessary. Change out of oil-
soaked clothes and do not keep oily rags in
your pocket.
• Air conditioning refrigerant forms a
poisonous gas if exposed to a naked flame
(including a cigarette). It can also cause skin
burns on contact.
Asbestos
• Asbestos dust can cause cancer if inhaled
or swallowed. Asbestos may be found in
gaskets and in brake and clutch linings.
When dealing with such components it is
safest to assume that they contain asbestos.
Special hazards
Hydrofluoric acid
• This extremely corrosive acid is formed
when certain types of synthetic rubber, found
in some O-rings, oil seals, fuel hoses etc, are
exposed to temperatures above 400
0C. The
rubber changes into a charred or sticky
substance containing the acid. Once formed,
the acid remains dangerous for years. If it
gets onto the skin, it may be necessary to
amputate the limb concerned.
• When dealing with a vehicle which has
suffered a fire, or with components salvaged
from such a vehicle, wear protective gloves
and discard them after use.
The battery
• Batteries contain sulphuric acid, which
attacks clothing, eyes and skin. Take care
when topping-up or carrying the battery.
• The hydrogen gas given off by the battery
is highly explosive. Never cause a spark or
allow a naked light nearby. Be careful when
connecting and disconnecting battery
chargers or jump leads.
Air bags
• Air bags can cause injury if they go off
accidentally. Take care when removing the
steering wheel and/or facia. Special storage
instructions may apply.
Diesel injection equipment
• Diesel injection pumps supply fuel at very
high pressure. Take care when working on
the fuel injectors and fuel pipes.
Warning: Never expose the
hands, face or any other part of
the body to injector spray; the
fuel can penetrate the skin with
potentially fatal results.
Remember...
DO
• Do use eye protection when using power
tools, and when working under the vehicle.
• Do wear gloves or use barrier cream to
protect your hands when necessary.
• Do get someone to check periodically
that all is well when working alone on the
vehicle.
• Do keep loose clothing and long hair well
out of the way of moving mechanical parts.
• Do remove rings, wristwatch etc, before
working on the vehicle – especially the
electrical system.
• Do ensure that any lifting or jacking
equipment has a safe working load rating
adequate for the job.
A few tips
DON’T
• Don’t attempt to lift a heavy component
which may be beyond your capability – get
assistance.
• Don’t rush to finish a job, or take
unverified short cuts.
• Don’t use ill-fitting tools which may slip
and cause injury.
• Don’t leave tools or parts lying around
where someone can trip over them. Mop
up oil and fuel spills at once.
• Don’t allow children or pets to play in or
near a vehicle being worked on.

Seat belts and seats
Note: The following checks are applicable to
all seat belts, front and rear.
MExamine the webbing of all the belts
(including rear belts if fitted) for cuts, serious
fraying or deterioration. Fasten and unfasten
each belt to check the buckles. If applicable,
check the retracting mechanism. Check the
security of all seat belt mountings accessible
from inside the vehicle.
MThe front seats themselves must be
securely attached and the backrests must
lock in the upright position.
Doors
MBoth front doors must be able to be opened
and closed from outside and inside, and must
latch securely when closed.
Vehicle identification
MNumber plates must be in good condition,
secure and legible, with letters and numbers
correctly spaced – spacing at (A) should be
twice that at (B).
MThe VIN plate (A) and homologation plate
(B) must be legible.
Electrical equipment
MSwitch on the ignition and check the
operation of the horn.
MCheck the windscreen washers and wipers,
examining the wiper blades; renew damaged
or perished blades. Also check the operation
of the stop-lights.
MCheck the operation of the sidelights and
number plate lights. The lenses and reflectors
must be secure, clean and undamaged.
MCheck the operation and alignment of the
headlights. The headlight reflectors must not
be tarnished and the lenses must be
undamaged.
MSwitch on the ignition and check the
operation of the direction indicators (including
the instrument panel tell-tale) and the hazard
warning lights. Operation of the sidelights and
stop-lights must not affect the indicators - if it
does, the cause is usually a bad earth at the
rear light cluster.
MCheck the operation of the rear foglight(s),
including the warning light on the instrument
panel or in the switch.
Footbrake
MExamine the master cylinder, brake pipes
and servo unit for leaks, loose mountings,
corrosion or other damage.
MThe fluid reservoir must be secure and the
fluid level must be between the upper (A) and
lower (B) markings.MInspect both front brake flexible hoses for
cracks or deterioration of the rubber. Turn the
steering from lock to lock, and ensure that the
hoses do not contact the wheel, tyre, or any
part of the steering or suspension mechanism.
With the brake pedal firmly depressed, check
the hoses for bulges or leaks under pressure.
Steering and suspension
MHave your assistant turn the steering wheel
from side to side slightly, up to the point where
the steering gear just begins to transmit this
movement to the roadwheels. Check for
excessive free play between the steering
wheel and the steering gear, indicating wear or
insecurity of the steering column joints, the
column-to-steering gear coupling, or the
steering gear itself.
MHave your assistant turn the steering wheel
more vigorously in each direction, so that the
roadwheels just begin to turn. As this is done,
examine all the steering joints, linkages,
fittings and attachments. Renew any
component that shows signs of wear or
damage. On vehicles with power steering,
check the security and condition of the
steering pump, drivebelt and hoses.
MCheck that the vehicle is standing level,
and at approximately the correct ride height.
Shock absorbers
MDepress each corner of the vehicle in turn,
then release it. The vehicle should rise and
then settle in its normal position. If the vehicle
continues to rise and fall, the shock absorber
is defective. A shock absorber which has
seized will also cause the vehicle to fail.

When jump-starting a car using a
booster battery, observe the following
precautions:
A)Before connecting the booster
battery, make sure that the ignition is
switched off.
B)Ensure that all electrical equipment
(lights, heater, wipers, etc) is
switched off.C)Make sure that the booster battery is
the same voltage as the discharged
one in the vehicle.
D)If the battery is being jump-started
from the battery in another vehicle,
the two vehcles MUST NOT TOUCH
each other.
E)Make sure that the transmission is in
neutral (or PARK, in the case of
automatic transmission).
Jump starting will get you out
of trouble, but you must correct
whatever made the battery go
flat in the first place. There are
three possibilities:
1The battery has been drained by
repeated attempts to start, or by
leaving the lights on.
2The charging system is not working
properly (alternator drivebelt slack
or broken, alternator wiring fault or
alternator itself faulty).
3The battery itself is at fault
(electrolyte low, or battery worn out).
Connect one end of the red jump lead to
the positive (+) terminal of the flat
batteryConnect the other end of the red lead to
the positive (+) terminal of the booster
battery.Connect one end of the black jump lead
to the negative (-) terminal of the
booster battery
Connect the other end of the black
jump lead to a bolt or bracket on the
engine block, well away from the
battery, on the vehicle to be started.

Make sure that the jump leads will not
come into contact with the fan, drive-
belts or other moving parts of the
engine.5
Start the engine using the booster
battery, then with the engine running at
idle speed, disconnect the jump leads in
the reverse order of connection.6

Ford Mondeo maintenance schedule
1•3
1
Maintenance schedule
The manufacturer’s recommended maintenance schedule for these
vehicles is as described below - note that the schedule starts from the
vehicle’s date of registration. These are the minimum maintenance
intervals recommended by the factory for Mondeos driven daily, but
subjected only to “normal” use. If you wish to keep your vehicle in
peak condition at all times, you may wish to perform some of these
procedures even more often. Because frequent maintenance
enhances the efficiency, performance and resale value of your vehicle,
we encourage you to do so. If your usage is not “normal”, shorter
intervals are also recommended - the most important examples of
these are noted in the schedule. These shorter intervals apply
particularly if you drive in dusty areas, tow a caravan or trailer, sit with
the engine idling or drive at low speeds for extended periods (ie, in
heavy traffic), or drive for short distances (less than four miles) in
below-freezing temperatures.
When your vehicle is new, it should be serviced by a Ford dealer
service department to protect the factory warranty. In many cases, the
initial maintenance check is done at no cost to the owner. Note that
this first free service (carried out by the selling dealer 1500 miles or 3
months after delivery), although an important check for a new vehicle,
is not part of the regular maintenance schedule, and is therefore not
mentioned here.
Weekly checks
m mCheck the engine oil level, and top-up if necessary
(Section 3)
m mCheck the brake fluid level, and top-up if necessary
(Section 3). If repeated topping-up is required, check the
system for leaks or damage at the earliest possible
opportunity (Sections 12 and 22)

17.4 Removing the automatic transmission
dipstick from its tube7.6A “MIN” and “MAX” marks on the
dipstick7.6B Adding automatic transmission fluid
through the dipstick tube
Every 10 000 miles
1The level of the automatic transmission fluid
should be carefully maintained. Low fluid level
can lead to slipping or loss of drive, while
overfilling can cause foaming, loss of fluid and
transmission damage.
2The transmission fluid level should only be
checked when the transmission is hot (at its
normal operating temperature). If the vehicle
has just been driven over 10 miles (15 miles in
a cold climate), and the fluid temperature is
160 to 175°F, the transmission is hot.
Caution: If the vehicle has just
been driven for a long time at
high speed or in city traffic in hot
weather, or if it has been pulling
a trailer, an accurate fluid level reading
cannot be obtained. In these
circumstances, allow the fluid to cool
down for about 30 minutes.
3Park the vehicle on level ground, apply the
handbrake, and start the engine. While the
engine is idling, depress the brake pedal and
move the selector lever through all the gear
ranges three times, beginning and ending in
“P”.
4Allow the engine to idle for one minute, then
(with the engine still idling) remove the dipstick
from its tube (see illustration). Note the
condition and colour of the fluid on the dipstick.
5Wipe the fluid from the dipstick with a clean
rag, and re-insert it into the filler tube until the
cap seats.
6Pull the dipstick out again, and note the
fluid level. The level should be between the
“MIN” and “MAX” marks. If the level is on the
“MIN” mark, stop the engine, and add the
specified automatic transmission fluid through
the dipstick tube, using a clean funnel if
necessary (see illustrations). It is important
not to introduce dirt into the transmission
when topping-up.
7Add the fluid a little at a time, and keep
checking the level as previously described
until it is correct.8The need for regular topping-up of the
transmission fluid indicates a leak, which
should be found and rectified without delay.
9The condition of the fluid should also be
checked along with the level. If the fluid at the
end of the dipstick is black or a dark reddish-
brown colour, or if it has a burned smell, the
fluid should be changed. If you are in doubt
about the condition of the fluid, purchase
some new fluid, and compare the two for
colour and smell.
1Check the operation of all external lights
and indicators (front and rear).
2Check for satisfactory operation of the
instrument panel, its illumination and warning
lights, the switches and their function lights.
3Check the horn(s) for satisfactory operation.
4Check all other electrical equipment for
satisfactory operation.
5Check all electrical wiring in the engine
compartment for correct routing, and for any
signs of physical or heat-damage or chafing.
Warning: Certain precautions
must be followed when checking
and servicing the battery.
Hydrogen gas, which is highly
flammable, is always present in the battery
cells, so keep lighted tobacco and all other
open flames and sparks away from the
battery. The electrolyte inside the battery
is actually dilute sulphuric acid, which will
cause injury if splashed on your skin or in
your eyes. It will also ruin clothes and
painted surfaces. When disconnecting the
battery, always detach the negative (earth)
lead first and connect it last!
Note: Before disconnecting the battery, refer
to Section 1 of Chapter 5.

9.1 Tools and materials required for
battery maintenance
1Face shield/safety goggles- When
removing corrosion with a brush, the acidic
particles can easily fly up into your eyes
2Baking soda- A solution of baking soda
and water can be used to neutralise corrosion
3Petroleum jelly- A layer of this on the
battery terminals will help prevent corrosion
4Battery terminal/lead cleaner- This wire
brush cleaning tool will remove all traces of
corrosion from the battery terminals and lead
clamps
5Treated felt washers- Placing one of
these on each terminal, directly under the
lead clamps, will help prevent corrosion
6Puller- Sometimes the lead clamps are
very difficult to pull off the terminals, even
after the nut has been completely slackened.
This tool pulls the clamp straight up and off
the terminal without damage
7Battery terminal/lead cleaner- Here is
another cleaning tool which is a slightly
different version of number 4 above, but does
the same thing
8Rubber gloves- Another safety item to
consider when servicing the battery;
remember, that’s acid inside the battery!

5Check all fluid reservoirs, filler caps, drain
plugs and fittings etc, looking for any signs of
leakage of oil, transmission and/or brake
hydraulic fluid, coolant and power steering
fluid. If the vehicle is regularly parked in the
same place, close inspection of the ground
underneath it will soon show any leaks; ignore
the puddle of water which will be left if the air
conditioning system is in use. As soon as a
leak is detected, its source must be traced
and rectified. Where oil has been leaking for
some time, it is usually necessary to use a
steam cleaner, pressure washer or similar, to
clean away the accumulated dirt, so that the
exact source of the leak can be identified.
Vacuum hoses
6It’s quite common for vacuum hoses,
especially those in the emissions system, to
be colour-coded, or to be identified by
coloured stripes moulded into them. Various
systems require hoses with different wall
thicknesses, collapse resistance and
temperature resistance. When renewing
hoses, be sure the new ones are made of the
same material.
7Often the only effective way to check a
hose is to remove it completely from the
vehicle. If more than one hose is removed, be
sure to label the hoses and fittings to ensure
correct installation.
8When checking vacuum hoses, be sure to
include any plastic T-fittings in the check.
Inspect the fittings for cracks, and check the
hose where it fits over the fitting for distortion,
which could cause leakage.
9A small piece of vacuum hose (quarter-inch
inside diameter) can be used as a
stethoscope to detect vacuum leaks. Hold
one end of the hose to your ear, and probe
around vacuum hoses and fittings, listening
for the “hissing” sound characteristic of a
vacuum leak.
Warning: When probing with the
vacuum hose stethoscope, be
very careful not to come into
contact with moving engine
components such as the auxiliary
drivebelt, radiator electric cooling fan, etc.
Fuel hoses
Warning: There are certain
precautions which must be taken
when inspecting or servicing fuel
system components. Work in a well-
ventilated area, and do not allow open
flames (cigarettes, appliance pilot lights,
etc.) or bare light bulbs near the work
area. Mop up any spills immediately, and
do not store fuel-soaked rags where they
could ignite.
10Check all fuel hoses for deterioration and
chafing. Check especially for cracks in areas
where the hose bends, and also just before
fittings, such as where a hose attaches to the
fuel filter.
11High-quality fuel line, usually identified by
the word “Fluoroelastomer” printed on thehose, should be used for fuel line renewal.
Never, under any circumstances, use
unreinforced vacuum line, clear plastic tubing
or water hose for fuel lines.
12Spring-type clamps are commonly used
on fuel lines. These clamps often lose their
tension over a period of time, and can be
“sprung” during removal. Replace all
spring-type clamps with screw clamps
whenever a hose is replaced.
Metal lines
13Sections of metal piping are often used
for fuel line between the fuel filter and the
engine. Check carefully to be sure the piping
has not been bent or crimped, and that cracks
have not started in the line.
14If a section of metal fuel line must be
renewed, only seamless steel piping should
be used, since copper and aluminium piping
don’t have the strength necessary to
withstand normal engine vibration.
15Check the metal brake lines where they
enter the master cylinder and ABS hydraulic
unit (if used) for cracks in the lines or loose
fittings. Any sign of brake fluid leakage calls
for an immediate and thorough inspection of
the brake system.
1With the vehicle parked on level ground,
apply the handbrake firmly and open the
bonnet. Using an inspection light or a small
electric torch, check all visible wiring within
and beneath the engine compartment.
2What you are looking for is wiring that is
obviously damaged by chafing against sharp
edges, or against moving suspension/
transmission components and/or the auxiliary
drivebelt, by being trapped or crushed
between carelessly-refitted components, or
melted by being forced into contact with the
hot engine castings, coolant pipes, etc. In
almost all cases, damage of this sort is
caused in the first instance by incorrect
routing on reassembly after previous work has
been carried out.
3Depending on the extent of the problem,
damaged wiring may be repaired by rejoining
the break or splicing-in a new length of wire,
using solder to ensure a good connection,
and remaking the insulation with adhesive
insulating tape or heat-shrink tubing, as
appropriate. If the damage is extensive, given
the implications for the vehicle’s future
reliability, the best long-term answer may well
be to renew that entire section of the loom,
however expensive this may appear.
4When the actual damage has been
repaired, ensure that the wiring loom is re-
routed correctly, so that it is clear of other
components, and not stretched or kinked, and
is secured out of harm’s way using the plastic
clips, guides and ties provided.
5Check all electrical connectors, ensuringthat they are clean, securely fastened, and
that each is locked by its plastic tabs or wire
clip, as appropriate. If any connector shows
external signs of corrosion (accumulations of
white or green deposits, or streaks of “rust”),
or if any is thought to be dirty, it must be
unplugged and cleaned using electrical
contact cleaner. If the connector pins are
severely corroded, the connector must be
renewed; note that this may mean the renewal
of that entire section of the loom - see your
local Ford dealer for details.
6If the cleaner completely removes the
corrosion to leave the connector in a
satisfactory condition, it would be wise to
pack the connector with a suitable material
which will exclude dirt and moisture,
preventing the corrosion from occurring
again; a Ford dealer may be able to
recommend a suitable product.
7Check the condition of the battery
connections - remake the connections or
renew the leads if a fault is found (see Chap-
ter 5). Use the same techniques to ensure that
all earth points in the engine compartment
provide good electrical contact through clean,
metal-to-metal joints, and that all are securely
fastened. (In addition to the earth connection
at the engine lifting eye, and that from the
transmission to the body/battery, there are
one or two earth points behind each headlight
assembly, and one below the power steering
fluid reservoir.)
8Refer to Section 31 for details of spark plug
(HT) lead checks.
Warning: The air conditioning
system is under high pressure.
Do not loosen any fittings or
remove any components until
after the system has been discharged. Air
conditioning refrigerant must be properly
discharged into an approved type of
container, at a dealer service department
or an automotive air conditioning repair
facility capable of handling R134a
refrigerant. Always wear eye protection
when disconnecting air conditioning
system fittings.
1The following maintenance checks should
be performed on a regular basis, to ensure
that the air conditioner continues to operate at
peak efficiency:
(a) Check the auxiliary drivebelt. If it’s worn
or deteriorated, renew it (see Section 11).
(b) Check the system hoses. Look for cracks,
bubbles, hard spots and deterioration.
Inspect the hoses and all fittings for oil
bubbles and seepage. If there’s any
evidence of wear, damage or leaks, renew
the hose(s).
(c) Inspect the condenser fins for leaves,
insects and other debris. Use a “fin

sender’s electrical connector, and use a
jumper wire to connect the white/red wire to a
clean earth point (bare metal) on the engine.
Switch on the ignition without starting the
engine. If the gauge now indicates Hot, renew
the sender.
5If the gauge still does not work, the circuit
may be open, or the gauge may be faulty. See
Chapter 12 for additional information.
Removal
6Unbolt the resonator support bracket from
the engine compartment front crossmember.
Slacken the two clamp screws securing the
resonator to the air mass meter and plenum
chamber hoses, then swing the resonator up
clear of the thermostat housing (see Chap-
ter 4).
7Drain the cooling system (see Chapter 1).
8Disconnect the expansion tank coolant
hose and the radiator top hose from the
thermostat housing’s water outlet, then
disconnect the metal coolant pipe/hose from
the thermostat.
9Unplug the electrical connector from the
sender (see illustration).
10Unscrew the sender and withdraw it.
Refitting
11Clean as thoroughly as possible the
opening in the thermostat housing, then apply
a light coat of sealant to the sender’s threads.
Screw in the sender and tighten it to the
specified torque wrench setting, and plug in
its electrical connector.
12Reconnect the hoses and refit the
resonator, top-up the cooling system (see
Chapter 1) and run the engine. Check for
leaks and proper gauge operation.
Coolant temperature sensor
Testing
13Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
14Unbolt the resonator support bracket
from the engine compartment front
crossmember. Slacken the two clamp screws
securing the resonator to the air mass meter
and plenum chamber hoses, then swing the
resonator up clear of the thermostat housing
(see Chapter 4).
15Unplug the electrical connector from the
sensor (see illustration).
16Using an ohmmeter, measure the
resistance between the sensor terminals.
Depending on the temperature of the sensor
tip, the resistance measured will vary, but
should be within the broad limits given in the
Specifications Section of this Chapter. If the
sensor’s temperature is varied - by removing
it (see below) and placing it in a freezer for a
while, or by warming it gently - its resistance
should alter accordingly.
17If the results obtained show the sensor to
be faulty, renew it.
18On completion, plug in the connector and
refit the resonator.

lead (see Chapter 5, Section 1).
20Unbolt the resonator support bracket
from the engine compartment front
crossmember. Slacken the two clamp screws
securing the resonator to the air mass meter
and plenum chamber hoses, then swing the
resonator up clear of the thermostat housing
(see Chapter 4).
21With the engine completely cool, remove
the expansion tank filler cap to release any
pressure, then refit the cap. Provided you
work swiftly and plug the opening as soon as
the sensor is unscrewed, coolant loss will thus
be minimised; this will avoid the draining of
the complete cooling system which would
otherwise be necessary (see Chapter 1).
22Unplug the electrical connector from the
sensor.
23Unscrew the sensor and withdraw it. If the
cooling system has not been drained, plug the
opening as quickly as possible.
Refitting
24Clean as thoroughly as possible the
opening in the thermostat housing, then apply
a light coat of sealant to the sensor’s threads.
Remove the material used to plug the sensor
hole (where applicable), and quickly install the
sensor to prevent coolant loss. Tighten the
sensor to the specified torque wrench setting,
and plug in its electrical connector.
25Refit the resonator, top-up the cooling
system (see Chapter 1) and run the engine,
checking for leaks.
Coolant low level switch
Testing
26The switch is a reed-type unit mounted in
the bottom of the cooling system expansion
tank, activated by a magnetic float. If the
coolant level falls to the “MIN” level or less,
the appropriate bulb lights in the warning
display.
27If the bulb fails to light during the 5-
second bulb test, check the bulb, and renew if
necessary as described in Chapter 12.
28To check the switch itself, unplug its
electrical connector, and use an ohmmeter to
measure the resistance across the switchterminals. With the float up, a resistance of
90 ohms should be measured; when it is
down, the resistance should increase to
approximately 150 kilohms.
29If the results obtained from the check are
significantly different from those expected,
the switch is faulty, and must be renewed.
30If the switch and bulb are proven to be
sound, the fault must be in the wiring or in the
auxiliary warning control assembly (see
Chapter 12).
Removal
31Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
32Remove the expansion tank (see Sec-
tion 7).
33Unplug the switch electrical connector.
34Release the switch by twisting its retainer
anti-clockwise, then withdraw it.
Refitting
35Refitting is the reverse of the removal
procedure. Refill the cooling system (see
Chapter 1). Start the engine, and check for
coolant leaks when it is fully warmed-up.
Note:Refer to the warnings given in Section 1
of this Chapter before starting work.
Radiator
Removal
Note:If leakage is the reason for removing the
radiator, bear in mind that minor leaks can
often be cured using a radiator sealant with
the radiator in situ.
1Remove the radiator fan and shroud
assembly (see Section 5).
2Disconnect the bottom hose from the
radiator.
3If the vehicle has automatic transmission,
disconnect the fluid cooler lines, and plug the
lines and fittings.
4If the vehicle has air conditioning, unscrew
the condenser mounting nuts or bolts, detach
the condenser from the radiator, and tie it to
the engine compartment front crossmember.

rings, and intend to re-use the same injectors,
remove the old nose seal and O-rings, and
discard them.
22Further testing of the injector(s) is beyond
the scope of the home mechanic. If you are in
doubt as to the status of any injector(s), it can
be tested at a dealer service department.
23Refitting is the reverse of the removal
procedure, noting the following points:
(a) Lubricate each nose seal and O-ring with
clean engine oil on installation.
(b) Locate each injector carefully in the fuel
rail recess, ensuring that the locating tab
on the injector head fits into the slot
provided in the rail. Tighten the bolts to
the specified torque.
(c) Fit a new seal to each fuel rail nose, and
ensure the seals are not displaced as the
rail is refitted. Ensure that the fuel rail is
settled fully in the manifold before
tightening the three bolts evenly and to
the torque wrench setting specified.
(d) Fasten the fuel feed and return quick-
release couplings as described in Sec-
tion 3.
(e) Ensure that the breather hose, vacuum
hose and wiring are routed correctly, and
secured on reconnection by any clips or
ties provided.
(f) On completion, switch the ignition on and
off five times, to activate the fuel pump and
pressurise the system, without cranking
the engine. Check for signs of fuel leaks
around all disturbed unions and joints
before attempting to start the engine.
Fuel pressure regulator
Check
24Refer to the fuel pump/fuel pressure
check procedure (see Section 8).
Renewal
25Relieve the residual pressure in the fuel
system (see Section 2), and equalise tank
pressure by removing the fuel filler cap.
Warning: This procedure will
merely relieve the increased
pressure necessary for the engine
to run - remember that fuel will
still be present in the system components,
and take precautions accordingly before
disconnecting any of them.26Disconnect the battery negative (earth)
lead - see Chapter 5, Section 1.
27Remove the plenum chamber (see
Section 4).
28Disconnect the vacuum hose from the
regulator.
29Unscrew the two regulator retaining bolts,
place a wad of clean rag to soak up any spilt
fuel, and withdraw the regulator (see
illustration).
30Refitting is the reverse of the removal
procedure, noting the following points:
(a) Renew the regulator sealing O-ring
whenever the regulator is disturbed.
Lubricate the new O-ring with clean
engine oil on installation.
(b) Locate the regulator carefully in the fuel
rail recess, and tighten the bolts to the
specified torque wrench setting.
(c) On completion, switch the ignition on and
off five times, to activate the fuel pump and
pressurise the system, without cranking
the engine. Check for signs of fuel leaks
around all disturbed unions and joints
before attempting to start the engine.
Idle speed control valve
Check
31Disconnect the battery negative (earth)
lead - see Chapter 5, Section 1.
32Raise the front of the vehicle, and support
it securely on axle stands.
Warning: Do not place any part of
your body under a vehicle when
it’s supported only by a jack!
33Unplug the valve’s electrical connector
(see illustration).
34Connect a 12-volt battery across the
valve’s terminals - positive (+) to terminal 37
(the green/yellow wire) and negative (-) to
terminal 21 (the black/yellow).
Caution: It is essential that the
correct polarity is observed, or
the diode incorporated in the
valve may be damaged.
35A distinct click should be heard each time
contact is made and broken. If not, measure
the resistance between the terminals. If the
resistance is as specified, the valve is okay
(but there may be a problem with the wiring or
the ECU). If the resistance is not as specified,
renew the valve (see below).36Plug in the valve’s electrical connector.
Renewal
37Disconnect the battery negative (earth)
lead - see Chapter 5, Section 1.
38Raise the front of the vehicle, and support
it securely on axle stands.
Warning: Do not place any part of
your body under a vehicle when
it’s supported only by a jack!
39Unplug the valve’s electrical connector.
40Unscrew the two retaining bolts, and
withdraw the valve from the inlet manifold
(see illustration).
41Since the valve’s individual components
are not available separately, and the complete
assembly must be renewed if it is thought to
be faulty, there is nothing to be lost by
attempting to flush out the passages, using
carburettor cleaner or similar solvent. This
won’t take much time or effort, and may well
cure the fault.
42Refitting is the reverse of the removal
procedure, noting the following points:
(a) Clean the mating surfaces carefully, and
always fit a new gasket whenever the
valve is disturbed.
(b) Tighten the bolts evenly and to the
specified torque wrench setting.
(c) Once the wiring and battery are
reconnected, start the engine and allow it
to idle. When it has reached normal
operating temperature, check that the idle
speed is stable, and that no induction (air)
leaks are evident. Switch on all electrical
loads (headlights, heated rear window,
etc), and check that the idle speed is still
correct.
