Repairs and Replacem
ents
Wh
en s
ervice parts are required, it is essential that only genuine Jaguar/Daimler replacements are used.
Attention is drawn to the following points concerning repa irs and the fitting of replacement parts and accessories:
Safety feat
ures embodied in the vehicle
may be impaired if other than genuine parts are fitted. In certain territories,
legislation prohibits the fitting of pa rts which are not produced to the vehi cle manufacturer's specification.
Torque wrench setting figures given i
n this manual must be strictly adhered to. Locking devices, where specified,
must be fitted. If the efficiency of a locking device is impaired during removal it must be renewed.
O w
ners purchasing accessories
while travelling abroad should ensure that the accessory and its fitted location on the
vehicle conform to mandatory requirements existing in their country of origin.
The vehicle warranty may be invali
dated by the fitting
of other than genuine Ja guar/Daimler parts. All
Jaguar/Daimler replacements have the fu ll backing of the factory warranty.
Jaguar/Daimler dealers are obliged to

supply only genuine service parts.
Thread Locking Devices
P a
tched Fasteners
Two types
of
patched fastener are essentially used on certai
n suspension, steering and other critical components, where
operational movement of the component necessitates positive thread locking. Standard patched fasteners have part
numbers bearing the suffix le tter M. For identification of special patched fa steners, refer to the list of patched fasteners
below, or the relevant component drawings.
Jaguar Specification JFS 02.01.02 patched fasteners incorporate a micro-encapsulated adhesive which is released into the
mating threads during tightening. Following final tightening, the adhesive in this type of patched fastener must be allowed a
period to cure before the component/vehicle is used. On removal, this type of fastener must be discarded and a new

WARNING: WASH HANDS AFTER HANDLING BRAKE FLUID. IF BRAKE FLUID COMES INTO CONTACT WITH THE EYES,
FLUSH EYES WITH COLD RUNNING WATER. IF IRRITATION PERSISTS SEEK MEDICAL ATTENTION. IF BRAKE FLUID IS
TAKEN INTERNALLY, DRINK WATER AND INDUCE VO MITING. GET MEDICAL ATTENTION IMMEDIATELY.
CAUTION: Remove brake fluid spillage imme diately from paint work with clean water.
1. Position vehi cl
e on a four-post lift.
2. Open engine compartment and fit paint work protection covers
to fenders.

3. NO
TE: Make sure the
brake-fluid level does not fall below the
fluid reservoir 'MIN' (minimum) mark when bleeding the brake
system.
Fill fluid reservoir to the 'MAX' (maximum) mark.

4. Prepare l e
ft-hand front, br
ake-caliper for bleeding.
Remove du
st cap.
Connect b
l
eed pipe
and fluid container to bleed nipple.
5. Bleed the brake.
1. Apply pressure to brake pedal
2. Open bleed nipple.
3. Fully depres s brake pedal.
4. Close bleed nipple.
5. Release brake pedal.
6. Wait two seconds to allow system to prime.
7. Repeat procedure until air- free brake fluid is expelled
from the caliper.
6. Tighten bleed nipple, see torque settings below.

2. Note that air in the fluid can temporarily result in PAS pump
noise, but this will not cause damage. The time allowances
mentioned in the above procedures are to reduce the possibility
of a customer collecting a vehicle while still subject to
