The maintenance intervals in this manual are provided with the
assumption that you, not the dealer, will be carrying out the work.
These are the minimum maintenance intervals recommended by us for
vehicles driven daily. If you wish to keep your vehicle in peak condition
at all times, you may wish to perform some of these procedures moreoften. We encourage frequent maintenance, because it enhances the
efficiency, performance and resale value of your vehicle.
When the vehicle is new, it should be serviced by a factory-
authorised dealer service department, in order to preserve the factory
warranty.

exhaust components will be warm during the
actual work, so try to anticipate any potential
problems before the engine and accessories
are hot.
5Park the vehicle on a level spot. Start the
engine and allow it to reach its normal
operating temperature (the needle on the
temperature gauge should be at least above
the bottom mark). Warm oil and contaminates
will flow out more easily. Turn off the engine
when it’s warmed up. Remove the oil filler cap
located next to the valve cover.
6Raise the vehicle and support it on axle
stands.
Warning: To avoid personal
injury, never get beneath the
vehicle when it is supported by
only by a jack. The jack provided
with your vehicle is designed solely for
raising the vehicle to remove and replace
the wheels. Always use axle stands to
support the vehicle when it becomes
necessary to place your body underneath
the vehicle.
7Being careful not to touch the hot exhaust
components, place the drain pan under the
drain plug in the bottom of the pan and
remove the plug (see illustration). You may
want to wear gloves while unscrewing the
plug the final few turns if the engine is really
hot.
8Allow the old oil to drain into the pan. It may
be necessary to move the pan farther under
the engine as the oil flow slows to a trickle.
Inspect the old oil for the presence of metal
shavings and chips.
9After all the oil has drained, wipe off the
drain plug with a clean rag. Even minute metal
particles clinging to the plug would
immediately contaminate the new oil.
10Clean the area around the drain plug
opening, refit the plug and tighten it securely,
but do not strip the threads.
11Move the drain pan into position under the
oil filter.
12Remove all tools, rags, etc. from under
the vehicle, being careful not to spill the oil in
the drain pan, then lower the vehicle.
13Loosen the oil filter (see illustration)by
turning it anti-clockwise with the filter wrench.
Any standard filter wrench should work. Oncethe filter is loose, use your hands to unscrew
it from the block. Just as the filter comes
away from the block, immediately tilt the open
end up to prevent the oil inside the filter from
spilling out.
Warning: The engine exhaust
pipes may still be hot, so be
careful.
14With a clean rag, wipe off the mounting
surface on the block. If a residue of old oil is
allowed to remain, it will smoke when the
block is heated up. It will also prevent the new
filter from seating properly. Also make sure
that the none of the old gasket remains stuck
to the mounting surface. It can be removed
with a scraper if necessary.
15Compare the old filter with the new one to
make sure they are the same type. Smear
some engine oil on the rubber gasket of the
new filter and screw it into place (see
illustration). Because over-tightening the
filter will damage the gasket, do not use
a filter wrench to tighten the filter. Tighten it by
hand until the gasket contacts the seating
surface. Then seat the filter by giving it an
additional 3/4-turn.
16Add new oil to the engine through the oil
filler cap next to the valve cover. Use a spout
or funnel to prevent oil from spilling onto the
top of the engine. Pour three litres of fresh oil
into the engine. Wait a few minutes to allow
the oil to drain into the pan, then check the
level on the oil dipstick (see “Weekly checks”).
If the oil level is at or near the H mark, refit the
filler cap hand tight, start the engine and allow
the new oil to circulate.
17Allow the engine to run for about a minute.
While the engine is running, look under the
vehicle and check for leaks at the sump drain
plug and around the oil filter. If either isleaking, stop the engine and tighten the plug
or filter slightly.
18Wait a few minutes to allow the oil to
trickle down into the pan, then recheck the
level on the dipstick and, if necessary, add
enough oil to bring the level to the H mark.
19During the first few trips after an oil
change, make it a point to check frequently
for leaks and proper oil level.
20The old oil drained from the engine cannot
be reused in its present state and should be
disposed of. Check with your local authority,
or with a local garage to see whether they will
accept the oil for recycling. Don’tpour used
oil into drains or onto the ground. After the oil
has cooled, it can be drained into a suitable
container (capped plastic jugs, topped
bottles, etc.) for transport to an approved
disposal site.
4 Spark plug check
2
1Spark plug renewal requires a spark plug
socket which fits onto a ratchet spanner. This
socket is lined with a rubber grommet to
protect the porcelain insulator of the spark
plug and to hold the plug while you insert it
into the spark plug hole. You will also need a
wire-type feeler gauge to check and adjust
the spark plug gap and a torque wrench to
tighten the new plugs to the specified torque
(see illustration).
2If you are replacing the plugs, purchase the
new plugs, adjust them to the proper gap and
then replace each plug one at a time. Note:
When buying new spark plugs, it’s essential
that you obtain the correct plugs for your
specific vehicle. This information can be found
in the Specifications Section at the beginning
of this Chapter, on the Vehicle Emissions
Control Information (VECI) label located on the
underside of the bonnet (where fitted)or in the
owner’s manual. If these sources specify
different plugs, purchase the spark plug type
specified on the VECI label because that
information is provided specifically for your
engine.

silencer and catalytic converter. If the
components can come in contact with the
body or suspension parts, secure the exhaust
system with new mounts.
5Check the running condition of the engine
by inspecting inside the end of the tailpipe.
The exhaust deposits here are an indication of
engine state-of-tune. If the pipe is black and
sooty or coated with white deposits, the
engine is in need of a tune-up, including a
thorough fuel system inspection.
11 Braking system - general
check and adjustment
2
Warning: The dust created by
the brake system may contain
asbestos, which is harmful to
your health. Never blow it out
with compressed air and don’t inhale any
of it. An approved filtering mask should be
worn when working on the brakes. Do not,
under any circumstances, use petroleum-
based solvents to clean brake parts. Use
brake system cleaner only! Try to use non-
asbestos replacement parts whenever
possible.
Note: For detailed photographs of the brake
system, refer to Chapter 9.
1In addition to the specified intervals, the
brakes should be inspected every time the
wheels are removed or whenever a defect is
suspected. Any of the following symptoms
could indicate a potential brake system
defect: The vehicle pulls to one side when the
brake pedal is depressed; the brakes make
squealing or dragging noises when applied;
brake pedal travel is excessive; the pedal
pulsates; brake fluid leaks, usually onto the
inside of the tyre or wheel.
2The disc brakes have built-in electrical wear
indicators which cause a warning lamp to
illuminate on the instrument panel when
they’re worn to the renewal point. When the
warning light comes on, replace the pads
immediately or expensive damage to the
discs can result.
3Loosen the wheel nuts.
4Raise the vehicle and place it securely on
axle stands.
5Remove the wheels.
Disc brakes
6There are two pads (an outer and an inner)
in each caliper. The pads are visible through
inspection holes in each caliper (see Haynes
Hint).
7Check the pad thickness by looking at each
end of the caliper and through the inspection
hole in the caliper body. If the lining material is
less than the thickness listed in this Chapter’s
Specifications, replace the pads. Note:Keep
in mind that the lining material is riveted or
bonded to a metal backing plate and the metal
portion is not included in this measurement.8If it is difficult to determine the exact
thickness of the remaining pad material by the
above method, or if you are at all concerned
about the condition of the pads, remove the
caliper(s), then remove the pads from the
calipers for further inspection (see Chapter 9).
9Once the pads are removed from the
calipers, clean them with brake cleaner and
re-measure them with a ruler or a vernier
caliper.
10Measure the disc thickness with a
micrometer to make sure that it still has
service life remaining. If any disc is thinner
than the specified minimum thickness,
replace it (refer to Chapter 9). Even if the disc
has service life remaining, check its condition.
Look for scoring, gouging and burned spots. If
these conditions exist, remove the disc and
have it resurfaced (see Chapter 9).
11Before refitting the wheels, check all
brake lines and hoses for damage, wear,
deformation, cracks, corrosion, leakage,
bends and twists, particularly in the vicinity of
the rubber hoses at the calipers (see
illustration). Check the clamps for tightness
and the connections for leakage. Make sure
that all hoses and lines are clear of sharp
edges, moving parts and the exhaust system.
If any of the above conditions are noted,
repair, reroute or replace the lines and/or
fittings as necessary (see Chapter 9).
Hydraulic brake servo check
12Sit in the driver’s seat and perform the
following sequence of tests.
13Start the engine, run it for about a minute
and turn it off. Then firmly depress the brake
several times - the pedal travel should
decrease with each application.
14With the brake fully depressed, start the
engine - the pedal should move down a little
when the engine starts.
15Depress the brake, stop the engine and
hold the pedal in for about 30 seconds - the
pedal should neither sink nor rise.
16If your brakes do not operate as
described above when the preceding tests
are performed, the brake servo is either in
need of repair or has failed. Refer to Chapter 9
for the removal procedure.
Handbrake
17Slowly pull up on the handbrake and
count the number of clicks you hear until the
handle is up as far as it will go. The
adjustment should be within the specified
number of clicks listed in this Chapter’s
Specifications. If you hear more or fewer
clicks, it’s time to adjust the handbrake (refer
to Chapter 9).
18An alternative method of checking the
handbrake is to park the vehicle on a steep hill
with the handbrake set and the transmission
in Neutral (be sure to stay in the vehicle during
this check!). If the handbrake cannot prevent
the vehicle from rolling, it is in need of
adjustment (see Chapter 9). Whenever a fault
is suspected, the brake discs should be
removed and the handbrake assemblies
themselves should be visually inspected.
12 Steering
and suspension check
2
Note: The steering linkage and suspension
components should be checked periodically.
Worn or damaged suspension and steering
linkage components can result in excessive
and abnormal tyre wear, poor ride quality and
vehicle handling and reduced fuel economy.
For detailed illustrations of the steering and
suspension components, refer to Chapter 10.
With the wheels on the ground
1Park the vehicle on level ground, turn the
engine off and set the handbrake. Check the
tyre pressures and check that the wheel nuts
are tightened to the specified torque.
2Push down at one corner of the vehicle,
then release it while noting the movement of
the body. It should stop moving and come to
rest in a level position with one or two
bounces. When bouncing the vehicle up and
down, listen for squeaks and noises from the
suspension components.
3If the vehicle continues to move up-and-
down or if it fails to return to its original

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.

16 Spark plug renewal
2
Refer to Section 4, renewing the plugs
regardless of their apparent condition.
17 Air cleaner element renewal
1
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
1
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

compressor belt first because of the way they
are arranged on the crankshaft pulley.
Because of this and because belts tend to
wear out more or less together, it is a good
idea to replace both belts at the same time.
Mark each belt and its appropriate pulley
groove so the new belts can be installed in
their proper positions.
10Take the old belts to the parts store in
order to make a direct comparison for length,
width and design.
11After replacing a ribbed drivebelt, make
sure that it fits properly in the ribbed grooves
in the pulleys (see illustration). It is essential
that the belt be properly centred.
12Adjust the belt(s) in accordance with the
procedure outlined above.
22 Front wheel bearing check
and adjustment

Check and repack
1In most cases the front wheel bearings will
not need servicing until the brake pads are
changed. However, the bearings should be
checked whenever the front of the vehicle is
raised for any reason. Several items, including
a torque wrench and special grease, are
required for this procedure (see illustration).2With the vehicle securely supported on axle
stands, spin each wheel and check for noise,
rolling resistance and freeplay.
3Grasp the top of each tyre with one hand
and the bottom with the other. Move the
wheel in-and-out on the spindle. If there’s any
noticeable movement, the bearings should be
checked and then repacked with grease or
renewed if necessary.
4Remove the wheel.
5Remove the brake caliper (see Chapter 9)
and hang it out of the way on a piece of wire.
A wood block of the appropriate width can be
slid between the brake pads to keep them
separated, if necessary. Also remove the
brake disc.
6Pry the dust cap out of the hub using a
screwdriver or a hammer and chisel (see
illustration).
7Straighten the bent ends of the cotter pin,
then pull the cotter pin out of the nut lock (see
illustration).Discard the cotter pin and use a
new one during reassembly.
8Remove the locknut, nut and washer from
the end of the spindle.
9Pull the hub out slightly, then push it back
into its original position. This should force theouter bearing off the spindle enough so it can
be removed (see illustration).
10Pull the hub off the spindle. Note:
Sometimes the inner wheel bearing and
grease seal remain attached to the spindle.
Grasp the back of the seal with both hands
and pull forward to remove them.
11If the grease seal is not already detached
from the hub, use a screwdriver to pry the seal
out of the rear of the hub. As this is done, note
how the seal is installed.
12If the inner wheel bearing is not already
detached from the hub, remove it at this time.
13Use solvent to remove all traces of the old
grease from the bearings, hub and spindle. A
small brush may prove helpful; however make
sure no bristles from the brush embed
themselves inside the bearing rollers. Allow
the parts to air dry.
14Carefully inspect the bearings for cracks,
heat discoloration, worn rollers, etc. Check
the bearing races inside the hub for wear and
damage. If the bearing races are defective,
the hubs should be taken to a machine
workshop with the facilities to remove the old
races and press new ones in. Note that the
bearings and races come as matched sets

22.1 Tools and materials needed for front
wheel bearing maintenance
1 Hammer
2 Grease - High-temperature grease that is
formulated specially for front wheel
bearings should be used
3 Wood block - If you have a scrap piece
of 2x4, it can be used to drive the new
seal into the hub
4 Needle-nose pliers - Used to straighten
and remove the cotter pin in the spindle
5 Torque wrench - This is very important in
this procedure; if the bearing is too tight,
the wheel won’t turn freely - if it’s too
loose, the wheel will “wobble” on the
spindle. Either way, it could mean
extensive damage
6 Screwdriver - Used to remove the seal
from the hub (a long screwdriver is
preferred)
7 Socket/breaker bar - Needed to loosen the
nut on the spindle if it’s extremely tight
8 Brush - Together with some clean
solvent, this will be used to remove old
grease from the hub and spindle
22.6 Dislodge the dust cap by working
around the outer circumference with a
hammer and chisel
22.7 Remove the cotter pin and discard it -
use a new one when the hub is reinstalled22.9 Pull the hub assembly forward
slightly - then push it back into position to
dislodge the outer wheel bearing
3261 Jaguar XJ6 21.11 When refitting ribbed (serpentine)
drivebelts, make sure the belt is centred
between the pulley edges (arrowed) - it
must not overlap either edge of the pulley

and old bearings should never be installed on
new races.
15Use high-temperature front wheel bearing
grease to pack the bearings. Work the grease
completely into the bearings, forcing it
between the rollers, cone and cage from the
back side (see illustration).
16Apply a thin coat of grease to the spindle
at the outer bearing seat, inner bearing seat,
shoulder and seal seat.
17Put a small quantity of grease inboard of
each bearing race inside the hub. Using your
finger, form a dam at these points to provide
extra grease availability and to keep thinned
grease from flowing out of the bearing (see
illustration).
18Place the grease-packed inner bearing
into the rear of the hub and put a little more
grease outboard of the bearing.
19Place a new seal over the inner bearing
and tap the seal evenly into place until it’s
flush with the hub (see illustration).
20Carefully place the hub assembly onto the
spindle and push the grease-packed outer
bearing into position (see illustration).
Adjustment
21Refit the washer and spindle nut. Tighten
the nut only slightly (no more than 16Nm/12
lbf ft of torque).
22Rotate the hub slowly in a forward
direction while tightening the spindle nut toapproximately 27Nm (20 lbf ft) to seat the
bearings. Remove any grease or burrs which
could cause excessive bearing play later.
23Loosen the spindle nut 1/4-turn, then
using your hand (not a spanner of any kind),
tighten the nut until it’s snug. Refit the nut lock
and a new cotter pin through the hole in the
spindle and the slots in the nut lock. If the
nut lock slots don’t line up, remove the nut
lock and turn it slightly until they do (see
illustration).
24Bend the ends of the cotter pin until
they’re flat against the nut. Cut off any extra
length which could interfere with the dust cap.
25Refit the dust cap, tapping it into place
with a hammer.
26Refit the brake disc and caliper in the
reverse order of removal (see Chapter 9).
27Refit the wheel on the hub and tighten the
wheel nuts.
28Grasp the top and bottom of the tyre and
check the bearings in the manner described
earlier in this Section.
29Lower the vehicle and tighten the wheel
nuts to the torque listed in this Chapter’s
Specifications.
23 Propshaft check
2
1Referring to Chapter 8, check the propshaft
centre bearing, universal joint and flexible
coupling for signs of wear or damage and
check that the propshaft fixings are tightened
to the specified torque.
24 Front wheel alignment check
5
1Accurate wheel alignment requires access
to specialised test equipment and as such
should be entrusted to a suitably equipped
Jaguar dealer or a tyre specialist (refer to
Chapter 10).
25 Headlight beam check
5
1Accurate adjustment of the headlight beam
is only possible using optical beam-setting
equipment, and this work should therefore be
carried out by a Jaguar dealer or garage with
the necessary facilities (see Chapter 12).
