power steering JAGUAR X308 1998 2.G Service Manual

The wiper and washer switch i s
on the righ
t-hand side of the steering column and controls the fo llowing functions when the
ignition switch in position II.
In the OFF position:
The windscreen wiper is stationary and in the parked positio
n.
In the intermittent wipe position:
The wi per ope
rates intermittently, with
a variable time delay between wipes.
The time del
ay can be varied by rotating the column sw
itch collar, which has six positions and varies the delay
between two and 20 seconds. The collar is turned counter-clockwise to increase the delay.
In the normal speed position:
The wiper oper a
tes continuously at normal speed.
In the high speed position:
The wiper ope r
ates continuously at high speed.
Flick wipe operation:
Is obt
ained by pulling the switch
stalk towards the steering wheel.
F
e
atures a single wipe at normal speed if
the switch stalk is released immediately.
Fe
atures continuous wipe action
at normal speed while the swit ch stalk position is held.
Wash/W
ipe Operation
Th
e
wash/wipe function:
Is operat
ed by th
e button at the end of the switch stalk.
Op
erate
s the washers and wiper, while the butt
on is depressed, for up to 20 seconds.
Provides an addit
ional three sweeps of
the wiper after the button is released.
Provid
es a single drip-wipe sweep, four seconds af
ter the wash/wipe sequence has been completed.
Is disabled if the 'Washer Flu
id Low' message is di
splayed, but manual operat ion is still available.

Parts List
Cran
kshaft Pulley
The combined crankshaft
pulley and torsio
nal vibration damper drives a single, seve n ribbed vee belt. The belt drives all of
the engine-mounted accessories; the generator, the power assi sted steering pump, the air-conditioning compressor and the
coolant water pump.
I
dler Pulley
An i
dler pulley, on the right-hand
accessory mounting, increases the wrap-angle around the generator pulley.
Coolant Pump Drive
The coolan
t pump pulley is the
uppermost of the accessory drive pulleys. Th e coolant pump is fitted between the two
cylinder banks on the front face of the engine.

Drive Belt

The drive belt should be inspected at every routine service for excessive wear and damage. A drive belt which displays
symptoms of cracking may be pe rfectly fit for further service.
Should cracking be detected, serviceability ma y be assessed using the following guidelines:
Fi
fteen cracks per rib over a 100 mm le
ngth of drive belt is acceptable.
Sec
tion(s) of belt missing from an
y rib is not acceptable and the drive belt must be renewed.
