0•10Weekly checks
There are some very simple checks which
need only take a few minutes to carry out, but
which could save you a lot of inconvenience
and expense.
These "Weekly checks" require no great skill
or special tools, and the small amount of time
they take to perform could prove to be very
well spent, for example;MKeeping an eye on tyre condition and
pressures, will not only help to stop them
wearing out prematurely, but could also save
your life.
M
Many breakdowns are caused by electrical
problems. Battery-related faults are particularly
common, and a quick check on a regular basis
will often prevent the majority of
these.MIf your car develops a brake fluid leak, the
first time you might know about it is when
your brakes don't work properly. Checking
the level regularly will give advance warning of
this kind of problem.
MIf the oil or coolant levels run low, the cost
of repairing any engine damage will be far
greater than fixing the leak, for example.

Brake fluid level
Warning:
l Brake fluid can harm your
eyes and will damage painted
surfaces, so use extreme caution
when handling and pouring it.
l Do not use fluid that has
been standing open for some
time, as it absorbs moisture
from the air, which can cause a
dangerous loss of braking
effectiveness.
Safety first!
lIf the reservoir requires repeated topping-
up this is an indication of a fluid leak
somewhere in the system, which should be
investigated immediately.
lIf a leak is suspected, the car should not be
driven until the braking system has been
checked. Never take any risks where brakes
are concerned.
• Make sure that your car is
on level ground.
• The fluid level in the
reservoir will drop slightly as
the brake pads wear down, but the fluid
level must never be allowed to drop
below the “MIN” mark.
The brake fluid reservoir is located on the
right-hand rear corner of the engine
compartment, on top of the master
cylinder.1The upper (MAX) and lower (MIN) fluid
level markings are on the side of the brake
fluid reservoir. The fluid level must always
be kept between these two marks.2
If topping up is necessary, first wipe
clean the area around the filler cap with a
clean cloth then unscrew the cap and
position it clear of the reservoir.3Carefully add fluid, avoiding spilling it on
the surrounding paintwork. Use only the
specified hydraulic fluid. After filling the
correct level, refit the cap and tighten it
securely. Wipe off any spilt fluid.4
Screenwash additives not only keep the
winscreen clean during foul weather, they also
prevent the washer system freezing in cold
weather - which is when you are likely to need it
most. Don’t top up using plain water as the
screenwash will become too diluted, and will
freeze during cold weather. On no account use
coolant antifreeze in the washer system -
this could discolour or damage paintwork.
Screen washer

If topping up is necessary, add water and
a screenwash additive in the quantities
recommended on the bottle.2The screen washer fluid reservoir is
located in the front, right-hand corner of
the engine compartment. The level is

Caution: Use only Castrol or Jaguar
hydraulic system mineral oil (HSMO) in the
power hydraulic system (available at
Jaguar dealer service departments).
1The power hydraulic system controls the ride
levelling and the brake servo systems. The
fluid reservoir also supplies the power
steering system on some models. The level
of the fluid should be carefully maintained. Low
fluid levels can adversely affect the riding and
braking capabilities of your vehicle. The power
hydraulic system fluid reservoir is located on
the right inner wing of the engine compartment.
1988 and 1989 models
2The fluid level can easily be checked by
viewing the reservoir sight glass. A green
indicator in the sight glass indicates an OK
condition, while a red indicator in the sight glass
requires fluid to be added (see illustration).
3If additional fluid is required, pop open the
plastic tab located on top of the reservoir cap
(see illustration).
4Insert the mineral oil dispensing tube into
the reservoir filler hole. Push down and turn
until the dispensing tube is locked in place.
5Add fluid until the green indicator in the
sight glass appears, then release the
dispensing tube by pushing downward and
turning the opposite direction of refitting.
1990 to 1994 models
6The fluid level can be checked by removing
the cap and observing the level of fluid on the
dipstick.
7Wipe off the fluid with a clean rag, reinsert
it, then withdraw it and read the fluid level
(see illustration). The dipstick is marked so
the fluid can be checked either cold or hot.
The level should be at the HOT mark if the
fluid was hot to the touch. It should be at the
COLD mark if the fluid was cool to the touch.
At no time should the fluid level drop below
the add mark.8If additional fluid is required, pour the
specified type directly into the reservoir, using
a funnel to prevent spills.
6 Battery check
and general information
1
Warning: Certain precautions
must be followed when working
with the battery. Hydrogen gas,
which is highly flammable, is
always present in the battery cells, so don’t
smoke, and keep naked flames and sparks
away from the battery. The electrolyte in
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 removing the
battery cables, always detach the negative
cable first and hook it up last!1A routine preventive maintenance program
for the battery in your vehicle is the only way
to ensure quick and reliable starts. But before
performing any battery maintenance, make
sure that you have the proper equipment
necessary to work safely around the battery
(see illustration).
2There are also several precautions that
should be taken whenever battery
maintenance is performed. Before servicing
the battery, always turn the engine and all
accessories off and disconnect the cable from
the negative terminal of the battery.
3The battery produces hydrogen gas, which
is both flammable and explosive. Never create
a spark, smoke or light a match around the
battery. Always charge the battery in a
ventilated area.
4Electrolyte contains poisonous and corrosive
sulphuric acid. Do not allow it to get in your
eyes, on your skin or on your clothes, and

6.1 Tools and materials required for
battery maintenance
1 Face shield/safety goggles - When
removing corrosion with a brush, the
acidic particles can fly up into your eyes
2 Baking soda - A solution of baking soda
and water can be used to neutralise
corrosion
3 Petroleum jelly - A layer of this on the
battery posts will help prevent corrosion
4 Battery post/cable cleaner - This wire
brush cleaning tool will remove all traces
of corrosion from the battery posts and
cable clamps
5 Treated felt washers - Placing one of
these on each post, directly under the
cable clamps, will help prevent corrosion
6 Puller - Sometimes the cable clamps are
difficult to pull off the posts, even after the
nut/bolt has been completely loosened.
This tool pulls the clamp straight up and
off the post without damage
7 Battery post/cable cleaner - Here is
another cleaning tool which is a slightly
different version of number 4 above, but
it does the same thing

and support it securely on axle stands.
Remove the wheel.
2Refit the special spring compressor tool
(JD115) as shown (see illustrations).
3Tighten the tool until the spacer is tight
against the spring pan, then remove the
spring pan bolts (see illustration).
4Slowly back off the wingnut on the special
tool until all tension is relieved from the spring.
Remove the tool, remove the pan, and remove
the coil spring.
5Refitting is the reverse of removal. Place the
coil spring in position with the spring pan
below it, refit the special tool and carefully
tighten the wingnut until the spring is
compressed enough to allow the pan to be
positioned and bolted to the lower control
arm. Be sure to tighten the pan bolts to the
torque listed in this Chapter’s Specifications.
9 Lower control arm-
removal and refitting
3
Warning: The lower control arms
cannot be removed without a
special spring compressor tool
(Jaguar tool JD115). Do not try to
remove a lower control arm without this
tool, or you could be seriously injured.1Loosen the wheel nuts, raise the vehicle
and support it securely on axle stands.
Remove the wheel.
2Remove the spring pan and the coil spring
(see Section 8).
3Detach the steering gear (see Section 17)
and lower it far enough to provide clearance
for the lower control arm pivot bolt.
4Remove the pivot bolt and nut (see
illustration). Note any washers behind the nut
and store them in a plastic bag.
5Remove the lower control arm.
6Refitting is the reverse of removal. Be sure
to refit any washers removed. Raise the
suspension with the trolley jack to simulate
normal ride height, then tighten the pivot bolt
and nut to the torque listed in this Chapter’s
Specifications. Refer to Section 8 for coil
spring refitting.
10 Shock absorber/coil spring
(rear)- removal and refitting
3
Note 1: Always renew both left and right
shocks at the same time to prevent handling
peculiarities and abnormal ride quality.
Note 2:If you’re replacing the shock absorbers
on an earlier vehicle with the self-levelling
system, we strongly recommend (and so doesJaguar) that you renew the self-levelling units
with conventional units (available at the dealer
as a retrofit kit for older vehicles equipped with
the self-levelling system).
1Loosen the rear wheel nuts. Raise the rear
of the vehicle and support it securely on axle
stands. Remove the rear wheels. Support the
control arm with a trolley jack. Place a block of
wood on the jack head to serve as a cushion.
2If you are removing/replacing the shocks on
a vehicle equipped with the self-levelling rear
suspension system, depressurise the system
by pumping the brake pedal until it feels hard
to push (this dissipates the pressure inside the
accumulator), then locate the hydraulic line
valve block just in front of the upper end of the
left rear shock (see illustration). Attach a
plastic hose to the bleeder screw (see
illustration), put the other end of the hose in a
catch bottle, crack the bleeder and drain off
as much fluid as possible. Disconnect the
hydraulic line that connects the left shock to
the valve block. Now locate the other valve
block just in front of the right rear shock;
disconnect the hydraulic line that connects
the right shock to this valve block too.
3Remove the lower shock absorber-to-
control arm nut and bolt (see illustration).
4Remove the upper mounting bolts (see
illustration)and remove the shock
absorber/coil spring assembly.

Warning: On models with an
airbag, do not apply excessive
force or severe shock to the
steering column shaft, or
accidental deployment of the airbag could
occur.
1Using a large syringe or hand pump, empty
the power steering fluid reservoir.
2Loosen the wheel nuts, raise the vehicle
and support it securely on axle stands.
Remove the wheels.
3Mark the relationship of the steering shaft
U-joint to the steering gear pinion shaft (see
illustration)to ensure proper alignment when
they’re reassembled. Remove the nut and bolt
that clamp the U-joint to the pinion shaft.
4Disconnect the power steering pressure
and return lines from the steering gear. Place
a container under the lines to catch spilledfluid. Plug the lines to prevent excessive fluid
loss and contamination. Discard the sealing
washers (new ones should be used when
reassembling).
5Disconnect the tie-rod ends from the
steering knuckle arms (see Section 17).
6Remove the nuts and bolts from the steering
gear mounting brackets (see illustration).
7Remove the steering gear assembly,
detaching the U-joint as you lower it. Don’t
damage the steering gear dust boots.
8Refitting is the reverse of removal. Ensure the
marks you made on the U-joint and the pinion
shaft are aligned before you tighten the U-joint
clamp bolt and nut. Tighten the mounting bolts,
the tie-rod end nuts and the U-joint shaft
clamping bolts to the specified torque.
9After lowering the vehicle, fill the reservoir
with the recommended fluid (see Chapter 1).
10Bleed the power steering system (see
Section 19).
11Have the front wheels aligned by a dealer
service department or alignment workshop
after reassembly.

1Raise the vehicle and support it securely on
axle stands. Remove the engine under-cover.
2Loosen the hose clamp and disconnect the
fluid return hose from the top of the pump
(see illustration)and drain the power steering
fluid from the reservoir into a clean container.
Unscrew the pressure line fitting from the
back of the pump. Plug the return hose and
the pressure line to prevent fluid from leaking
and to protect the power steering system
from contamination.
3Remove the bolts (see illustration)that
attach the power steering pump adapter to
the auxiliary shaft housing.

General repair proceduresREF•5
Whenever servicing, repair or overhaul work
is carried out on the car or its components, it
is necessary to observe the following
procedures and instructions. This will assist in
carrying out the operation efficiently and to a
professional standard of workmanship.
Joint mating faces and gaskets
When separating components at their
mating faces, never insert screwdrivers or
similar implements into the joint between the
faces in order to prise them apart. This can
cause severe damage which results in oil
leaks, coolant leaks, etc upon reassembly.
Separation is usually achieved by tapping
along the joint with a soft-faced hammer in
order to break the seal. However, note that
this method may not be suitable where
dowels are used for component location.
Where a gasket is used between the mating
faces of two components, ensure that it is
renewed on reassembly, and fit it dry unless
otherwise stated in the repair procedure. Make
sure that the mating faces are clean and dry,
with all traces of old gasket removed. When
cleaning a joint face, use a tool which is not
likely to score or damage the face, and remove
any burrs or nicks with an oilstone or fine file.
Make sure that tapped holes are cleaned
with a pipe cleaner, and keep them free of
jointing compound, if this is being used,
unless specifically instructed otherwise.
Ensure that all orifices, channels or pipes
are clear, and blow through them, preferably
using compressed air.
Oil seals
Oil seals can be removed by levering them
out with a wide flat-bladed screwdriver or
similar tool. Alternatively, a number of self-
tapping screws may be screwed into the seal,
and these used as a purchase for pliers or
similar in order to pull the seal free.
Whenever an oil seal is removed from its
working location, either individually or as part
of an assembly, it should be renewed.
The very fine sealing lip of the seal is easily
damaged, and will not seal if the surface it
contacts is not completely clean and free from
scratches, nicks or grooves. If the original
sealing surface of the component cannot be
restored, and the manufacturer has not made
provision for slight relocation of the seal
relative to the sealing surface, the component
should be renewed.
Protect the lips of the seal from any surface
which may damage them in the course of
fitting. Use tape or a conical sleeve where
possible. Lubricate the seal lips with oil before
fitting and, on dual-lipped seals, fill the space
between the lips with grease.
Unless otherwise stated, oil seals must be
fitted with their sealing lips toward the
lubricant to be sealed.
Use a tubular drift or block of wood of the
appropriate size to install the seal and, if the
seal housing is shouldered, drive the seal
down to the shoulder. If the seal housing isunshouldered, the seal should be fitted with
its face flush with the housing top face (unless
otherwise instructed).
Screw threads and fastenings
Seized nuts, bolts and screws are quite a
common occurrence where corrosion has set
in, and the use of penetrating oil or releasing
fluid will often overcome this problem if the
offending item is soaked for a while before
attempting to release it. The use of an impact
driver may also provide a means of releasing
such stubborn fastening devices, when used
in conjunction with the appropriate
screwdriver bit or socket. If none of these
methods works, it may be necessary to resort
to the careful application of heat, or the use of
a hacksaw or nut splitter device.
Studs are usually removed by locking two
nuts together on the threaded part, and then
using a spanner on the lower nut to unscrew
the stud. Studs or bolts which have broken off
below the surface of the component in which
they are mounted can sometimes be removed
using a stud extractor. Always ensure that a
blind tapped hole is completely free from oil,
grease, water or other fluid before installing
the bolt or stud. Failure to do this could cause
the housing to crack due to the hydraulic
action of the bolt or stud as it is screwed in.
When tightening a castellated nut to accept
a split pin, tighten the nut to the specified
torque, where applicable, and then tighten
further to the next split pin hole. Never
slacken the nut to align the split pin hole,
unless stated in the repair procedure.
When checking or retightening a nut or bolt
to a specified torque setting, slacken the nut
or bolt by a quarter of a turn, and then
retighten to the specified setting. However,
this should not be attempted where angular
tightening has been used.
For some screw fastenings, notably
cylinder head bolts or nuts, torque wrench
settings are no longer specified for the latter
stages of tightening, “angle-tightening” being
called up instead. Typically, a fairly low torque
wrench setting will be applied to the
bolts/nuts in the correct sequence, followed
by one or more stages of tightening through
specified angles.
Locknuts, locktabs and washers
Any fastening which will rotate against a
component or housing during tightening
should always have a washer between it and
the relevant component or housing.
Spring or split washers should always be
renewed when they are used to lock a critical
component such as a big-end bearing
retaining bolt or nut. Locktabs which are
folded over to retain a nut or bolt should
always be renewed.
Self-locking nuts can be re-used in non-
critical areas, providing resistance can be felt
when the locking portion passes over the bolt
or stud thread. However, it should be noted
that self-locking stiffnuts tend to lose theireffectiveness after long periods of use, and
should be renewed as a matter of course.
Split pins must always be replaced with
new ones of the correct size for the hole.
When thread-locking compound is found
on the threads of a fastener which is to be re-
used, it should be cleaned off with a wire
brush and solvent, and fresh compound
applied on reassembly.
Special tools
Some repair procedures in this manual
entail the use of special tools such as a press,
two or three-legged pullers, spring
compressors, etc. Wherever possible, suitable
readily-available alternatives to the
manufacturer’s special tools are described,
and are shown in use. In some instances,
where no alternative is possible, it has been
necessary to resort to the use of a
manufacturer’s tool, and this has been done
for reasons of safety as well as the efficient
completion of the repair operation. Unless you
are highly-skilled and have a thorough
understanding of the procedures described,
never attempt to bypass the use of any
special tool when the procedure described
specifies its use. Not only is there a very great
risk of personal injury, but expensive damage
could be caused to the components involved.
Environmental considerations
When disposing of used engine oil, brake
fluid, antifreeze, etc, give due consideration to
any detrimental environmental effects. Do not,
for instance, pour any of the above liquids
down drains into the general sewage system,
or onto the ground to soak away. Many local
council refuse tips provide a facility for waste
oil disposal, as do some garages. If none of
these facilities are available, consult your local
Environmental Health Department, or the
National Rivers Authority, for further advice.
With the universal tightening-up of
legislation regarding the emission of
environmentally-harmful substances from
motor vehicles, most current vehicles have
tamperproof devices fitted to the main
adjustment points of the fuel system. These
devices are primarily designed to prevent
unqualified persons from adjusting the fuel/air
mixture, with the chance of a consequent
increase in toxic emissions. If such devices
are encountered during servicing or overhaul,
they should, wherever possible, be renewed
or refitted in accordance with the vehicle
manufacturer’s requirements or current
legislation.
Note: It is
antisocial and
illegal to dump oil
down the drain.
