1998 JAGUAR X308 body mounting

The fluid reservo
ir:
Is lo

cated in the engine compartment, mounted on the engine compartment fuse box bracket.
Incorporates

a 10 micron, li
fetime, integral filter.
Has a cap
acity of 0.4 liter.
Has a dipsti

ck incorporated into the filler cap for checking the fluid level.
A new reservoir must be fitted if the steering rack, pump or fluid cooler are renewed.
Fluid C
ooler

P
arts List
The fluid cooler:
Is
resiliently mounted on th
e front body cross member.
Coo
ls the fluid before it is
returned to the reservoir.
Is
of the wire-bound tube type.
Has i

ntegral hoses.
Supply and Return Hoses a

nd Pipework
The supply and return h
oses and
pipework deliver fluid at high pressure from the pump to th e steering rack assembly. The
fluid is then returned to th e reservoir through the cooler tube. The high pressure supply hose contains two cable-type
attenuators, one at each end, to reduce nois e. The return pipe is clipped to the steering rack housing by a resilient
mounting.
