position, a worn or weak shock absorber is
probably the reason.
4Repeat the above check at each of the
three remaining corners of the vehicle.
Under the vehicle
5Raise the vehicle with a trolley jack and
support it securely on axle stands. See
“Jacking and towing”for proper jacking
points.
6Check the shock absorbers for evidence of
fluid leakage. Make sure that any fluid noted is
from the shocks and not from any other
source. Also check the rubber mounts at each
end for deterioration If the shock absorbers
fail any of the tests above replace the shocks
as a set.
7Check the tyres for irregular wear patterns
and proper inflation. See “Weekly checks”for
information regarding tyre wear.
8Inspect the universal joint between the
steering shaft and the steering gear housing.
Check the steering gear housing for grease
leakage. Make sure that the dust seals and
boots are not damaged and that the boot
clamps are not loose (see illustration). Check
the steering linkage for looseness or damage.
Look for loose bolts, broken or disconnected
parts and deteriorated rubber bushings on all
suspension and steering components (see
illustration). While an assistant turns the
steering wheel from side to side, check the
steering components for free movement,
chafing and binding. If the steering
components do not seem to be reacting with
the movement of the steering wheel, try to
determine where the slack is located.
9Check the balljoints moving each lower arm
up and down with a crowbar to ensure that its
balljoint has no play. If any balljoint does have
play, replace it. See Chapter 10 for the front
balljoint renewal procedure. Check the tie-rod
ends for excessive play.
10Inspect the balljoint and tie-rod end boots
for damage and leaking grease (see
illustration. Replace the balljoints and tie-rod
ends with new ones if they are damaged (see
Chapter 10).
13 Seat belt check
1
1Check the seat belts, buckles, latch plates
and guide loops for any obvious damage or
signs of wear.
2Make sure the seat belt reminder light
comes on when the key is turned on.
3The seat belts are designed to lock up
during a sudden stop or impact, yet allow free
movement during normal driving. The
retractors should hold the belt against your
chest while driving and rewind the belt when
the buckle is unlatched.
4If any of the above checks reveal problems
with the seat-belt system, replace parts as
necessary.Note:Check with your local dealer
service department; the seat belt system
should be covered under the factory warranty.
14 General lubrication
2
1Obtain a good quality, multi-purpose
lithium-base grease. You’ll also need a grease
gun and other materials to properly lubricate
the chassis (see illustration). Occasionallyplugs will be installed rather than grease
fittings. If so, grease fittings will have to be
purchased and installed.
2Look under the car and see if grease fittings
or plugs are installed. If there are plugs,
remove them and buy grease fittings, which
will thread into the component. A dealer or
motor factors will be able to supply the
correct fittings. Straight, as well as angled,
fittings are available.
3For easier access under the car, raise it with
a jack and place axle stands under the
chassis. Make sure it’s safely supported by
the stands. If the wheels are to be removed at
this interval for tyre rotation or brake
inspection, loosen the wheel nuts slightly
while the car is still on the ground.
4Before beginning, force a little grease out of
the nozzle to remove any dirt from the end of
the gun. Wipe the nozzle clean with a rag.
5With the grease gun and plenty of clean
rags, crawl under the car and begin
lubricating all the front suspension parts that
are equipped with a grease fitting.
6Lubricate the rear driveshafts (see
illustration). Wipe each fitting clean and push
the nozzle firmly over it. Pump the gun until
grease is expelled from the U-joint cap seal.
7Wipe away any excess grease from the
components and the grease fitting. Repeat
the procedure for the remaining fittings.

1The air filter is located inside a housing at
the left side of the engine compartment. To
remove the air filter, release the four spring
clips that secure the two halves of the air
cleaner housing together, then lift the cover
up and remove the air filter element (see
illustration).
Caution: Never drive the car with the air
cleaner removed. Excessive engine wear
could result and backfiring could even
cause a fire under the bonnet.
2Wipe out the inside of the air cleaner
housing.
3Place the new filter into the air cleaner
housing, making sure it seats properly.
4Refitting the cover is the reverse of removal.
18 Fuel filter renewal
2
Warning: Petrol is extremely
flammable, so take extra
precautions when you work on
any part of the fuel system.
Don’t smoke or allow open flames or bare
light bulbs near the work area, and don’t
work in a garage where a natural gas-typeappliance (such as a water heater or
clothes dryer) with a pilot light is present.
Since petrol is carcinogenic, wear latex
gloves when there’s a possibility of being
exposed to fuel, and, if you spill any fuel on
your skin, rinse it off immediately with soap
and water. Mop up any spills immediately
and do not store fuel-soaked rags where
they could ignite. The fuel system is under
constant pressure, so, if any fuel lines are
to be disconnected, the fuel pressure in
the system must be relieved first (see
Chapter 4 for more information). When you
perform any kind of work on the fuel
system, wear safety glasses and have a
Class B type fire extinguisher on hand.
1The canister type filter is mounted
underneath the car on the passenger’s side
frame rail just in front of the left rear tyre.
2Depressurise the fuel system (refer to
Chapter 4), then disconnect the cable from
the negative terminal of the battery.
3On 1988 to 1990 models, detach the banjo
bolt from the outlet side of the filter then
remove the union from the inlet side of the
filter. Unscrew the filter mounting bolt and
remove the filter (see illustration).
4On 1991 to 1994 models, the fuel filter has
quick-disconnect fittings that do not require 8Clean and lubricate the handbrake cable,
along with the cable guides and levers. This
can be done by smearing some of the chassis
grease onto the cable and its related parts
with your fingers.
9Open the bonnet and smear a little chassis
grease on the bonnet latch mechanism. Have
an assistant pull the bonnet release lever from
inside the car as you lubricate the cable at the
latch.
10Lubricate all the hinges (door, bonnet,
etc.) with engine oil to keep them in proper
working order.
11The key lock cylinders can be lubricated
with spray graphite or silicone lubricant, which
is available at motor factors.12Lubricate the door weather-stripping with
silicone spray. This will reduce chafing and
retard wear.
15 Road test

Instruments and electrical
equipment
1Check the operation of all instruments and
electrical equipment.
2Make sure that all instruments read
correctly, and switch on all electrical
equipment in turn, to check that it functions
properly.
Steering and suspension
3Check for any abnormalities in the steering,
suspension, handling or road “feel”.
4Drive the car, and check that there are no
unusual vibrations or noises.
5Check that the steering feels positive, with
no excessive “sloppiness”, or roughness, and
check for any suspension noises when
cornering and driving over bumps.
Drivetrain
6Check the performance of the engine and
transmission, listening for any unusual noises.7Make sure that the engine runs smoothly
when idling, and that there is no hesitation
when accelerating.
8Check that the gear changing action of the
transmission is smooth and progressive and
that the drive is taken up smoothly from a
standing start.
Braking system
9Make sure that the car does not pull to one
side when braking, and that the wheels do not
lock prematurely when braking hard.
10Check that there is no vibration through
the steering when braking.
11Check that the handbrake operates
correctly without excessive movement of the
lever, and that it holds the car stationary on a
slope.
12Test the operation of the brake servo unit
as follows. With the engine off, depress the
footbrake four or five times to exhaust the
vacuum. Hold the brake pedal depressed, then
start the engine. As the engine starts, there
should be a noticeable “give” in the brake
pedal as vacuum builds up. Allow the engine to
run for at least two minutes, and then switch it
off. If the brake pedal is depressed now, it
should be possible to detect a hiss from the
servo as the pedal is depressed. After about
four or five depressions, no further hissing
should be heard, and the pedal should feel
considerably harder.

4Remove the water pump mounting bolts
(see illustration).
Note 1:The water pump is sold as a complete
assembly, including the rear housing with the
hose connections. Unless the rear housing is
corroded or cracked, many Jaguar mechanics
only refit the pump assembly itself, using the
original rear housing with all its hoses intact.
However, if the engine has a great deal of
years or mileage on it, it would be a good idea
to renew those hoses as well, in which case
the new rear housing can be installed.
Note 2:There are three different lengths of
water pump bolts. The longer bolts retain the
pump and rear housing to the engine(see
illustration 7.3).
5If the pump doesn’t come loose right away,
tap it with a soft-faced hammer to break the
gasket seal. Be careful not to hit the radiator
fins with the pump during removal.
6Thoroughly clean all sealing surfaces,
removing all traces of gasket or sealant from
the back of the pump and the face of the
housing.
7Apply a bead of RTV sealant to the sealing
surface on the back of the pump. Refit the
pump and bolts, tightening the bolts to the
torque listed in this Chapter’s Specifications.
8Refit the remaining parts in the reverse
order of removal. Note:If the pump has been
renewed after many miles of usage, it’s a good
idea to also renew the hoses connected to the
water pump housing(see illustrations). Refer
to Chapter 2A for intake manifold removal to
access the coolant pipes and hoses. If you
have noticed water leaks or stains on the left
side of the engine, the leaks may be coming
from these pipes and hoses.
9Refill the cooling system (see Chapter 1),
run the engine and check for leaks and proper
operation.
9 Coolant temperature
sender unit- check and
renewal
2
Warning: Do not start this
procedure until the engine is
completely cool.
Check
1If the coolant temperature gauge is
inoperative, check the fuses first (Chapter 12).
2If the temperature gauge indicates
excessive temperature after running awhile,
see the Fault finding section at the rear of the
manual.
3If the temperature gauge indicates Hot as
soon as the engine is started cold, disconnect
the wire at the coolant temperature sender
(see illustration). If the gauge reading drops,
renew the sender unit. If the reading remains
high, the wire to the gauge may be shorted to
ground, or the gauge is faulty.
4If the coolant temperature gauge fails to
show any indication after the engine has been
warmed up, (approx. 10 minutes) and the
fuses checked out OK, shut off the engine.
Disconnect the wire at the sender unit and,
using a jumper wire, connect the wire to a
clean ground on the engine. Briefly turn on the
ignition without starting the engine. If the
gauge now indicates Hot, renew the sender
unit.
5If the gauge fails to respond, the circuit may
be open or the gauge may be faulty - see
Chapter 12 for additional information.
Renewal
6Drain the coolant (see Chapter 1).
7Disconnect the electrical connector from
the sender unit.8Using a deep socket or a spanner, remove
the sender unit.
9Refit the new unit and tighten it securely.
Do not use thread sealant as it may
electrically insulate the sender unit.
10Reconnect the wiring connector, refill the
cooling system and check for coolant leakage
and proper gauge function.
10 Heating and air conditioning
blower motors- circuit check
and component renewal
3
Warning: Later models are
equipped with airbags. To
prevent accidental deployment
of the airbag, which could cause
personal injury or damage to the airbag
system, DO NOT work in the vicinity of the
steering wheel or instrument panel. Jaguar
recommends that, on airbag-equipped
models, the following procedure should be
left to a dealer service department or other
repair workshop because of the special
tools and techniques required to disable
the airbag system.
1Disconnect the battery negative cable.
Caution: If the stereo in your vehicle is
equipped with an anti-theft system, make
sure you have the correct activation code
before disconnecting the battery.
2There are two blower motors, one under the
left side of the dash and one behind the glove
compartment (see illustration). If the blower
doesn’t work, check the fuse and all
connections in the circuit for looseness and
corrosion. Make sure the battery is fully
charged. To access the right blower, remove
the glove compartment liner, the glove
compartment door and the right lower dash
panel (see Chapter 11).
Warning: When working around
the area behind the glove box,
watch out for a strip of sheet
metal bracing that has a very
sharp edge (see illustration). Apply some
heavy duct tape to the edge of the brace
before beginning work in this area, or you
could injure your hands.

procedure.
5Run the engine and check for proper
functioning of the heater (and air conditioning,
if equipped).
Control checks
6The climate-control system uses an all-
electronic control panel that sends digital
information to the climate control computer.
There is little the home mechanic can do to
troubleshoot or test the system. The factory
recommends that diagnosis be performed at a
dealership.
7If there is a problem in just one area of
climate control, put the controls through their
entire range of operation and check the
system responses, i.e. set the controls to
COLD, the fan to low and the temperature to
65° F. In this mode the Manual LED should be
lit and the air conditioning compressor should
engage. Try all of the fan speeds and try the
temperature on HOT, then feel for warm air
coming from the ducts. Note:Between each
try of the different controls, wait 20 seconds or
so for the heater/air conditioning system to
adjust before checking for a response.
8When each control button is pushed two
times, its LED light should go on or off. Renew
the control assembly if any of the warning
lights don’t work.
9On 1988 and 1989 models, if the climate
controls do not respond to any driver input,
check with your Jaguar dealer before
renewing the ECU or control panel. A service
part is available (a resistor, #JLM 1901) that
can be installed at one of the control panel
terminals that may fix the problem without any
other parts being renewed. Instructions are
included with the part.
10Check the vacuum lines to the several
vacuum motors that operate the heater/air
conditioning functions. Look for pinched or
blocked hoses and leaks.11Each of the vacuum “servo motors” in the
system can be checked with a hand-held
vacuum pump (see illustration). Apply vacuum
and watch that the door or control it operates is
working.
12Further diagnosis of the controls or
climate control ECU are best left to a Jaguar
dealership or other qualified repair facility.
13 Air conditioning and heating
system- check and
maintenance
1
Air conditioning system
Warning: The air conditioning
system is under high pressure.
Do not loosen any hose fittings
or remove any components until
the system has been discharged. Air
conditioning refrigerant should be properly
discharged into an EPA-approved
recovery/recycling unit by a dealer service
department or an automotive air
conditioning repair facility. Always wear
eye protection when working near 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) Inspect the condition of the compressor
drivebelt. If it is worn or deteriorated,
renew it (see Chapter 1).
b) Check the drivebelt tension and, if
necessary, adjust it (see Chapter 1).
c) Inspect the system hoses. Look for
cracks, bubbles, hardening and
deterioration. Inspect the hoses and all
fittings for oil bubbles or seepage. If there
is any evidence of wear, damage or
leakage, renew the hose(s).d) Inspect the condenser fins for leaves,
bugs and any other foreign material that
may have embedded itself in the fins. Use
a “fin comb” or compressed air to remove
debris from the condenser.
e) Make sure the system has the correct
refrigerant charge.
2It’s a good idea to operate the system for
about ten minutes at least once a month. This
is particularly important during the winter
months because long term non-use can
cause hardening, and subsequent failure, of
the seals.
3Leaks in the air conditioning system are
best spotted when the system is brought up
to operating temperature and pressure, by
running the engine with the air conditioning
ON for five minutes. Shut the engine off and
inspect the air conditioning hoses and
connections. Traces of oil usually indicate
refrigerant leaks.
4Because of the complexity of the air
conditioning system and the special
equipment required to effectively work on it,
accurate troubleshooting of the system
should be left to a professional technician.
5If the air conditioning system doesn’t
operate at all, check the fuse panel and the air
conditioning relay (refer to Chapter 12 for
relay locations and testing). See Sections 4, 9
and 12 for electrical checks of heating/air
conditioning system components.
6The most common cause of poor cooling is
simply a low system refrigerant charge. If a
noticeable drop in cool air output occurs, the
following quick check will help you determine
if the refrigerant level is low.
Checking the refrigerant charge
7Warm the engine up to normal operating
temperature.
8Place the air conditioning temperature
selector at the coldest setting and put the
Cooling, heating and air conditioning systems 3•11

3261 Jaguar XJ6 12.3b Remove the four screws (three are shown here) holding the
control assembly in the control/radio housing
12.11 Check the operation of the vacuum servo motors; in this
case, vacuum is applied to the servo on the right blower case -
the flapper door (arrowed) should operate

blower at the highest setting. Open the doors
(to make sure the air conditioning system
doesn’t cycle off as soon as it cools the
passenger compartment).
9With the compressor engaged - the clutch
will make an audible click and the centre of
the clutch will rotate. After the system reaches
operating temperature, feel the two pipes
connected to the evaporator at the bulkhead
(see illustration).
10The pipe (thinner tubing) leading from the
condenser outlet to the evaporator should be
cold, and the evaporator outlet line (the
thicker tubing that leads back to the
compressor) should be slightly colder (3 to
10° F). If the evaporator outlet is considerably
warmer than the inlet, the system needs a
charge. Insert a thermometer in the centre air
distribution duct while operating the air
conditioning system - the temperature of the
output air should be 35 to 40° F below the
ambient air temperature (down to approxi-
mately 40° F). If the ambient (outside) air
temperature is very high, say 110° F, the duct
air temperature may be as high as 60° F, but
generally the air conditioning is 30 to 50° F
cooler than the ambient air. If the air isn’t as
cold as it used to be, the system probably
needs a charge. Further inspection or testing
of the system is beyond the scope of the
home mechanic and should be left to a
professional.
11Inspect the sight glass (see illustration).
If the refrigerant looks foamy when running,
it’s low. When ambient temperatures are very
hot, bubbles may show in the sight glass even
with the proper amount of refrigerant. With the
proper amount of refrigerant, when the air
conditioning is turned off, the sight glass
should show refrigerant that foams, then
clears. Note:1993 and 1994 models are
equipped with R-134a refrigerant systems and
do not have a sight glass.Heating systems
12If the air coming out of the heater vents
isn’t hot, the problem could stem from any of
the following causes:
a) The thermostat is stuck open, preventing
the engine coolant from warming up
enough to carry heat to the heater core.
Renew the thermostat (see Section 3).
b) A heater hose is blocked, preventing the
flow of coolant through the heater core.
Feel both heater hoses at the bulkhead.
They should be hot. If one of them is cold,
there is an obstruction in one of the hoses
or in the heater core, or the heater control
valve is shut. Detach the hoses and back
flush the heater core with a water hose. If
the heater core is clear but circulation is
impeded, remove the two hoses and flush
them out with a water hose.
c) If flushing fails to remove the blockage
from the heater core, the core must be
renewed.(see Section 11).
13If the blower motor speed does not
correspond to the setting selected on the
blower switch, the problem could be a badfuse, circuit, control panel or climate control
computer (see Sections 10 and 12).
14If there isn’t any air coming out of the
vents:
a) Turn the ignition ON and activate the fan
control. Place your ear at the heating/air
conditioning register (vent) and listen.
Most motors are audible. Can you hear
the motor running?
b) If you can’t (and have already verified that
the blower switch and the blower motor
resistor are good), the blower motor itself
is probably bad (see Section 10).
15If the carpet under the heater core is
damp, or if antifreeze vapour or steam is
coming through the vents, the heater core is
leaking. Remove it (see Section 11) and refit a
new unit (most radiator shops will not repair a
leaking heater core).
16Inspect the drain hose from the heat/AC
assembly at the right side of the bulkhead,
make sure it is not clogged (see illustration).
If there is a humid mist coming from the
system ducts, this hose may be plugged. In
some early models, the hose may have been
pinched during assembly or blocked with
insulation or underseal.

with an additional specialised inertia switch.
This later device switches OFF all ignition fed
circuits, locks the fuel filler cap, locks the boot
(only if doors are locked) and unlocks the
doors if they are locked during the accident.
All these functions are directed by the inertia
switch. The inertia switch is located behind
the left kick panel. Refer to Chapter 12 for
more information.
Exhaust system
The exhaust system includes an exhaust
manifold equipped with an exhaust oxygen
sensor, a catalytic converter, an exhaust pipe,
and a silencer.
The catalytic converter is an emission
control device added to the exhaust system to
reduce pollutants. A single-bed converter is
used in combination with a three-way
(reduction) catalyst. See Chapter 6 for more
information regarding the catalytic converter.
2 Fuel pressure relief
1
Warning: Petrol is extremely
flammable, so take extra
precautions when you work on
any part of the fuel system.
Don’t smoke or allow open flames or bare
light bulbs near the work area, and don’t
work in a garage where a natural gas-type
appliance (such as a water heater or a
clothes dryer) with a pilot light is present.
Since petrol is carcinogenic, wear latex
gloves when there’s a possibility of being
exposed to fuel, and, if you spill any fuel on
your skin, rinse it off immediately with soap
and water. Mop up any spills immediately
and do not store fuel-soaked rags wherethey could ignite. The fuel system is under
constant pressure, so, if any fuel lines are
to be disconnected, the fuel pressure in
the system must be relieved first. When
you perform any kind of work on the fuel
system, wear safety glasses and have a
Class B type fire extinguisher on hand.
1Before servicing any fuel system
component, you must relieve the fuel pressure
to minimise the risk of fire or personal injury.
2Remove the fuel filler cap - this will relieve
any pressure built up in the tank.
3Remove the fuel pump relay from the main
relay panel (see illustrations). Note:These
models are equipped with a fuel pump relay
that is located in various areas of the vehicle
depending on the year. On 1988 and 1989
models, the fuel pump relay is under the
glovebox. On 1990 to 1992 models, the fuel
pump relay is in the engine compartment on
the left side, attached to the brake pedal
hanger. On 1993 models, the fuel pump relay
is in the boot. On 1994 models, it’s in the
engine compartment on the right side of the
bulkhead. Refer to the relay location charts in
Chapter 12 for additional information.
4Start the engine and wait for the engine to
stall, then turn the ignition key to Off.
Disconnect the cable from the negativeterminal of the battery before beginning any
work on the fuel system.
Caution: If the stereo in your vehicle is
equipped with an anti-theft system, make
sure you have the correct activation code
before disconnecting the battery.
5The fuel system is now depressurised.
Note:Place a rag around the fuel line before
removing any hose clamp or fitting to prevent
any residual fuel from spilling onto the engine.
3 Fuel pump/fuel pressure-
check
2
Warning: Petrol is extremely
flammable, so take extra
precautions when you work on
any part of the fuel system. See
the Warning in Section 2.
Note: To perform the fuel pressure test, you
will need to obtain a fuel pressure gauge and
adapter set (fuel line fittings).
Note: On 1988 to 1990 models, the fuel pump
may chatter excessively and the engine may
stall frequently during hot weather. If stalling
occurs, the engine will restart after a cool-
down period. Dual fuel pumps can be installed
by a dealer service department or other
qualified repair facility to remedy this problem.
Preliminary inspection
1Should the fuel system fail to deliver the
proper amount of fuel, or any fuel at all,
inspect it as follows. Remove the fuel filler
cap. Have an assistant turn the ignition key to
the ON position (engine not running) while you
listen at the fuel filler opening. You should
hear a whirring sound that lasts for a couple of
seconds. On 1988 to 1990 models, listen
behind the left rear wheel (external fuel pump)
for the fuel pump sound.
2If you don’t hear anything, check the fuel
pump relay (see illustration 2.3a, b or c)and
4•2 Fuel and exhaust systems

Refitting
7Insert the distributor into the engine in
exactly the same relationship to the block that
it was in when removed.
8If the distributor does not seat completely,
recheck the alignment marks between the
distributor base and the block to verify that
the distributor is in the same position it was in
before removal. Also check the rotor to see if
it’s aligned with the mark you made on the
edge of the distributor base.
9Refit the distributor hold-down bolt(s).
10The remainder of refitting is the reverse of
removal.
10 Charging system- general
information and precautions
The charging system includes the alternator,
an internal voltage regulator, a charge
indicator light, load dump module, the battery,
an ignition ON relay, an in-line fuse and the
wiring between all the components (see
illustration). The charging system supplies
electrical power for the ignition system, the
lights, the radio, etc. The alternator is driven by
a drivebelt at the front of the engine.
The purpose of the voltage regulator is to
limit the alternator’s voltage to a preset value.
This prevents power surges, circuit overloads,
etc., during peak voltage output.
The alternator load dump module protects
the electrical circuits from excessive voltage
surges. When the battery cables are removed
large amounts of transient voltage is released
through the electrical circuits. This device
diverts up to 30 load volts of excess voltage to
earth by way of a voltage dependent resistor.
The in-line fuse is a special fuse installed
into the circuit with the engine compartment
wiring harness (see Chapter 12). The in-line
fuse protects the electrical system in the
event of excess voltage surges or a power to
earth short circuit. Refer to Chapter 12 for
additional information concerning the in-line
fuses and their locations.
1993 and 1994 models have a Starter Logic
Relay. This microprocessor (computer)
gathers information from the ignition switch,
linear gear position switch, park/neutral
switch, the security switch and the electronic
door lock system. If all the conditions are in
order, the computer allows battery voltage to
be transferred from the ignition switch to the
starter/solenoid assembly.
The charging system doesn’t ordinarily
require periodic maintenance. However, the
drivebelt, battery and wires and connections
should be inspected at the intervals outlined
in Chapter 1.
The dashboard warning light should come
on when the ignition key is turned to Start,
then should go off immediately. If it remains
on, there is a malfunction in the charging
system. Some vehicles are also equipped with
a voltage gauge. If the voltage gaugeindicates abnormally high or low voltage,
check the charging system (see Section 11).
Be very careful when making electrical
circuit connections to a vehicle equipped with
an alternator and note the following:
a) When reconnecting wires to the alternator
from the battery, note their polarity.
b) Before using arc welding equipment to
repair any part of the vehicle, disconnect
the wires from the alternator and the
battery terminals.
c) Never start the engine with a battery
charger connected.
d) Always disconnect both battery leads
before using a battery charger.
e) The alternator is driven by an engine
drivebelt which could cause serious injury
if your hand, hair or clothes become
entangled in it with the engine running.
f) Because the alternator is connected
directly to the battery, it could arc or
cause a fire if overloaded or shorted out.
g) Wrap a plastic bag over the alternator and
secure it with rubber bands before steam
cleaning the engine.

Note:1993 and 1994 models are equipped
with a Starter Logic Relay. This microprocessor
(computer) gathers information from theignition switch, linear gear position switch,
park/neutral switch, the security switch and the
electronic door lock system. If all the conditions
are in order, the computer allows battery
voltage to be transferred from the ignition
switch to the starter/solenoid assembly. If all
the components of the charging system are
working properly and the system still does not
charge properly, have the Starter Logic Relay
diagnosed by a dealer service department.
1If a malfunction occurs in the charging
circuit, don’t automatically assume that the
alternator is causing the problem. First check
the following items:
a) Check the drivebelt tension and its
condition. Renew it if worn or damaged.
b) Make sure the alternator mounting and
adjustment bolts are tight.
c) Inspect the alternator wiring harness and
the electrical connectors at the alternator
and voltage regulator. They must be in
good condition and tight.
d) Check the fusible link (if equipped)
located between the starter solenoid and
the alternator or the large main fuses in
the engine compartment. If it’s burned,
determine the cause, repair the circuit
and renew the link or fuse (the vehicle
won’t start and/or the accessories won’t
work if the fusible link or fuse blows).
e) Check all the in-line fuses that are in series
with the charging system circuit (see
Chapter 12).The location of these fuses
and fusible links may vary from year and

1 General information
These models feature a “unibody”
construction, using a floor pan with front and
rear frame side rails which support the body
components, front and rear suspension
systems and other mechanical components.
Certain components are particularly vulnerable
to accident damage and can be unbolted and
repaired or replaced. Among these parts are
the body mouldings, bumpers, front wings,
bonnet and boot lids and all glass.
Only general body maintenance practices
and body panel repair procedures within the
scope of the do-it-yourselfer are included in
this Chapter.
2 Body- maintenance
1
1The condition of your vehicle’s body is very
important, because the resale value depends
a great deal on it. It’s much more difficult to
repair a neglected or damaged body than it is
to repair mechanical components. The hidden
areas of the body, such as the wheel wells,
the frame and the engine compartment, areequally important, although they don’t require
as frequent attention as the rest of the body.
2Once a year, or every 12,000 miles, it’s a
good idea to have the underside of the body
steam cleaned. All traces of dirt and oil will be
removed and the area can then be inspected
carefully for rust, damaged brake lines, frayed
electrical wires, damaged cables and other
problems. The front suspension components
should be greased after completion of this job.
3At the same time, clean the engine and the
engine compartment with a steam cleaner or
water soluble degreaser.
4The wheel wells should be given close
attention, since undercoating can peel away
and stones and dirt thrown up by the tyres
can cause the paint to chip and flake, allowing
rust to set in. If rust is found, clean down to
the bare metal and apply an anti-rust paint.
5The body should be washed about once a
week. Wet the vehicle thoroughly to soften the
dirt, then wash it down with a soft sponge and
plenty of clean soapy water. If the surplus dirt
is not washed off very carefully, it can wear
down the paint.
6Spots of tar or asphalt thrown up from the
road should be removed with a cloth soaked
in solvent.
7Once every six months, wax the body and
chrome trim. If a chrome cleaner is used to
remove rust from any of the vehicle’s plated
parts, remember that the cleaner also removes
part of the chrome, so use it sparingly.
3 Vinyl trim- maintenance
1
Don’t clean vinyl trim with detergents,
caustic soap or petroleum-based cleaners.
Plain soap and water works just fine, with a
soft brush to clean dirt that may be ingrained.
Wash the vinyl as frequently as the rest of the
vehicle.
After cleaning, application of a high quality
rubber and vinyl protectant will help prevent
oxidation and cracks. The protectant can also
be applied to weather-stripping, vacuum lines
and rubber hoses (which often fail as a result
of chemical degradation) and to the tyres.
4 Upholstery and carpets-
maintenance
1
1Every three months remove the carpets or
mats and clean the interior of the vehicle
(more frequently if necessary). Vacuum the
upholstery and carpets to remove loose dirt
and dust.
2Leather upholstery requires special care.
Stains should be removed with warm water
and a very mild soap solution. Use a clean,
damp cloth to remove the soap, then wipe

again with a dry cloth. Never use alcohol,
petrol, nail polish remover or thinner to clean
leather upholstery.
3After cleaning, regularly treat leather
upholstery with a leather wax. Never use car
wax on leather upholstery.
4In areas where the interior of the vehicle is
subject to bright sunlight, cover leather seats
with a sheet if the vehicle is to be left out for
any length of time.
5 Body repair- minor damage
3
Repair of minor scratches
1If the scratch is superficial and does not
penetrate to the metal of the body, repair is
very simple. Lightly rub the scratched area
with a fine rubbing compound to remove
loose paint and built-up wax. Rinse the area
with clean water.
2Apply touch-up paint to the scratch, using a
small brush. Continue to apply thin layers of
paint until the surface of the paint in the
scratch is level with the surrounding paint.
Allow the new paint at least two weeks to
harden, then blend it into the surrounding
paint by rubbing with a very fine rubbing
compound. Finally, apply a coat of wax to the
scratch area.
3If the scratch has penetrated the paint and
exposed the metal of the body, causing the
metal to rust, a different repair technique is
required. Remove all loose rust from the
bottom of the scratch with a pocket knife,
then apply rust inhibiting paint to prevent the
formation of rust in the future. Using a rubber
or nylon applicator, coat the scratched area
with glaze-type filler. If required, the filler can
be mixed with thinner to provide a very thin
paste, which is ideal for filling narrow
scratches. Before the glaze filler in the scratch
hardens, wrap a piece of smooth cotton cloth
around the tip of a finger. Dip the cloth in
thinner and then quickly wipe it along the
surface of the scratch. This will ensure that
the surface of the filler is slightly hollow. The
scratch can now be painted over as described
earlier in this section.
Repair of dents
4When repairing dents, the first job is to pull
the dent out until the affected area is as close
as possible to its original shape. There is no
point in trying to restore the original shape
completely as the metal in the damaged area
will have stretched on impact and cannot be
restored to its original contours. It is better to
bring the level of the dent up to a point which
is about 1/8-inch below the level of the
surrounding metal. In cases where the dent is
very shallow, it is not worth trying to pull it out
at all.
5If the back side of the dent is accessible, it
can be hammered out gently from behindusing a soft-face hammer. While doing this,
hold a block of wood firmly against the
opposite side of the metal to absorb the
hammer blows and prevent the metal from
being stretched.
6If the dent is in a section of the body which
has double layers, or some other factor makes
it inaccessible from behind, a different
technique is required. Drill several small holes
through the metal inside the damaged area,
particularly in the deeper sections. Screw
long, self-tapping screws into the holes just
enough for them to get a good grip in the
metal. Now the dent can be pulled out by
pulling on the protruding heads of the screws
with locking pliers.
7The next stage of repair is the removal of
paint from the damaged area and from an
inch or so of the surrounding metal. This is
done with a wire brush or sanding disc in a
drill motor, although it can be done just as
effectively by hand with sandpaper. To
complete the preparation for filling, score the
surface of the bare metal with a screwdriver or
the tang of a file, or drill small holes in the
affected area. This will provide a good grip
for the filler material. To complete the repair,
see the subsection on filling and painting later
in this Section.
Repair of rust holes or gashes
8Remove all paint from the affected area and
from an inch or so of the surrounding metal
using a sanding disc or wire brush mounted in
a drill motor. If these are not available, a few
sheets of sandpaper will do the job just as
effectively.
9With the paint removed, you will be able to
determine the severity of the corrosion and
decide whether to replace the whole panel, if
possible, or repair the affected area. New
body panels are not as expensive as most
people think and it is often quicker to refit a
new panel than to repair large areas of rust.
10Remove all trim pieces from the affected
area except those which will act as a guide to
the original shape of the damaged body, such
as headlight shells, etc. Using metal snips or a
hacksaw blade, remove all loose metal and
any other metal that is badly affected by rust.
Hammer the edges of the hole in to create a
slight depression for the filler material.
11Wire brush the affected area to remove
the powdery rust from the surface of the
metal. If the back of the rusted area is
accessible, treat it with rust inhibiting paint.
12Before filling is done, block the hole in
some way. This can be done with sheet metal
riveted or screwed into place, or by stuffing
the hole with wire mesh.
13Once the hole is blocked off, the affected
area can be filled and painted. See the
following subsection on filling and painting.
Filling and painting
14Many types of body fillers are available,
but generally speaking, body repair kits which
contain filler paste and a tube of resinhardener are best for this type of repair work.
A wide, flexible plastic or nylon applicator will
be necessary for imparting a smooth and
contoured finish to the surface of the filler
material. Mix up a small amount of filler on a
clean piece of wood or cardboard (use the
hardener sparingly). Follow the
manufacturer’s instructions on the package,
otherwise the filler will set incorrectly.
15Using the applicator, apply the filler paste
to the prepared area. Draw the applicator
across the surface of the filler to achieve the
desired contour and to level the filler surface.
As soon as a contour that approximates the
original one is achieved, stop working the
paste. If you continue, the paste will begin to
stick to the applicator. Continue to add thin
layers of paste at 20-minute intervals until the
level of the filler is just above the surrounding
metal.
16Once the filler has hardened, the excess
can be removed with a body file. From then
on, progressively finer grades of sandpaper
should be used, starting with a 180-grit paper
and finishing with 600-grit wet-or-dry paper.
Always wrap the sandpaper around a flat
rubber or wooden block, otherwise the
surface of the filler will not be completely flat.
During the sanding of the filler surface, the
wet-or-dry paper should be periodically rinsed
in water. This will ensure that a very smooth
finish is produced in the final stage.
17At this point, the repair area should be
surrounded by a ring of bare metal, which in
turn should be encircled by the finely
feathered edge of good paint. Rinse the repair
area with clean water until all of the dust
produced by the sanding operation is gone.
18Spray the entire area with a light coat of
primer. This will reveal any imperfections in
the surface of the filler. Repair the
imperfections with fresh filler paste or glaze
filler and once more smooth the surface with
sandpaper. Repeat this spray-and-repair
procedure until you are satisfied that the
surface of the filler and the feathered edge of
the paint are perfect. Rinse the area with
clean water and allow it to dry completely.
19The repair area is now ready for painting.
Spray painting must be carried out in a warm,
dry, windless and dust free atmosphere.
These conditions can be created if you have
access to a large indoor work area, but if you
are forced to work in the open, you will have
to pick the day very carefully. If you are
working indoors, dousing the floor in the work
area with water will help settle the dust which
would otherwise be in the air. If the repair area
is confined to one body panel, mask off the
surrounding panels. This will help minimise
the effects of a slight mismatch in paint
colour. Trim pieces such as chrome strips,
door handles, etc., will also need to be
masked off or removed. Use masking tape
and several thickness of newspaper for the
masking operations.
20Before spraying, shake the paint can
thoroughly, then spray a test area until the
11•2 Bodywork and fittings
3261 Jaguar XJ6

spray painting technique is mastered. Cover
the repair area with a thick coat of primer. The
thickness should be built up using several thin
layers of primer rather than one thick one.
Using 600-grit wet-or-dry sandpaper, rub
down the surface of the primer until it is very
smooth. While doing this, the work area
should be thoroughly rinsed with water and
the wet-or-dry sandpaper periodically rinsed
as well. Allow the primer to dry before
spraying additional coats.
21Spray on the top coat, again building up
the thickness by using several thin layers of
paint. Begin spraying at the top of the repair
area and then, using a side-to-side motion,
work down until the whole repair area and
about two inches of the surrounding original
paint is covered. Remove all masking material
10 to 15 minutes after spraying on the final
coat of paint. Allow the new paint at least two
weeks to harden, then use a very fine rubbing
compound to blend the edges of the new
paint into the existing paint. Finally, apply a
coat of wax.
6 Body repair- major damage
5
1Major damage must be repaired by an auto
body workshop specifically equipped to
perform unibody repairs. These workshops
have the specialised equipment required to
do the job properly.
2If the damage is extensive, the body must
be checked for proper alignment or the
vehicle’s handling characteristics may be
adversely affected and other components
may wear at an accelerated rate.
3Due to the fact that most of the major body
components (bonnet, front wings, etc.) are
separate and replaceable units, any seriously
damaged components should be replaced
rather than repaired. Sometimes thecomponents can be found in a scrapyard that
specialises in used vehicle components, often
at considerable savings over the cost of new
parts.
7 Hinges and locks-
maintenance
1
Once every 3000 miles, or every three
months, the hinges and latch assemblies on
the doors, bonnet and boot should be given a
few drops of light oil or lock lubricant. The
door latch strikers should also be lubricated
with a thin coat of grease to reduce wear and
ensure free movement. Lubricate the door
and boot locks with spray-on graphite
lubricant.
8 Windscreen and fixed glass-
replacement
5
Replacement of the windscreen and fixed
glass requires the use of special fast-setting
adhesive/caulk materials and some
specialised tools. It is recommended that
these operations be left to a dealer or a
workshop specialising in glass work.
9 Bonnet and boot lid support
struts- removal and refitting
1
1Open the bonnet or boot lid and support it
securely.
2Using a small screwdriver, detach the
retaining clips at both ends of the support
strut. Then pry or pull sharply to detach it from
the vehicle(see illustrations).
3Refitting is the reverse of removal.
10 Bonnet- removal,
refitting and adjustment
2
Note:The bonnet is heavy and somewhat
awkward to remove and refit - at least two
people should perform this procedure.
Removal and refitting
1Use blankets or pads to cover the wings
and the area in front of the bonnet. This will
protect the body and paint as the bonnet is
lifted off.
2Make marks or scribe a line around the
bonnet hinge to ensure proper alignment
during refitting.
3Disconnect any cables or wires that will
interfere with removal.
4Have an assistant support the bonnet.
Remove the hinge-to-bonnet screws or bolts
(see illustration).
5Lift off the bonnet.
6Refitting is the reverse of removal.
Adjustment
7Before the bonnet can be adjusted
properly, both bonnet striker assemblies
