1998 JAGUAR X308 engine

Date of
Manufacture
T
h
e date of manufacture (Build Date) of a vehicle is define
d as the calendar month and year in which the bodyshell and
powertrain are combined and the completed vehicle leaves the production line. For certain markets, VIN labels carry the
month and year of manufacture. For other markets, the vehicle Build Date is also displayed on a metal plate located at the
top of the battery tray in the trunk.
ANTI-T
HEFT LABELS
F
or
some markets, anti-theft labels bearing the VIN printed on
a special anti-forgery background are positioned on certain
body components. An additional anti-theft label is positioned on the LH side of the engine/automatic transmission casing.
Anti-theft labels must not be removed from a vehicle unless necessitated by component renewal.

When the vehicle is being towed on its own wheels:
Loc a
l regulations for the towing of ve
hicles must be followed. In some co untries the registration number of the
towing vehicle and an 'On Tow' sign or warning triangle must be displayed at the rear of the towed vehicle.
The gear s
elector lever

rossbeam
A
fully stressed, pressed steel and tube fa
brication with integral lower wishbone tie bars, the crossbeam is secured to the
body on four resilient mountings.
The crossbeam incorporates mounting points for:
The u
pper and lower wish
bone fulcrum bolts.
The
stabilizer bar
The power steering rack. The engine h

ydramounts.
R

oad springs.
Slots and cam reaction pl ates on the crossbeam provide for ad justment of suspension geometry.

WHE
N CHANGING A WHEEL, ENSURE THAT THE VEHICLE CANNOT MOVE. ALWAYS APPLY THE PARK BRAKE AND
SELECT TRANSMISSION 'P' POSITION.
NEVER RUN THE ENGINE WITH ONE WHEEL OFF THE GROUND, FOR EXAMPLE, WHEN CHANGING THE WHEEL. THE
VEHICLE COULD MOVE.
TIGHTEN THE WHEEL NUTS TO SPECIFICATION. WHEELS MAY COME LOOSE IF OVER OR UNDER TIGHTENED.
USE WHEELS AND WHEEL NUTS DESI GNED FOR XJ SERIES VEHICLES ONLY. AFTERMARKET WHEELS OR WHEEL
NUTS MAY NOT FIT OR FUNCTION PROPERLY AND COULD CAUSE INJURY OR DAMAGE.
In
spection and Verification
To maximize ti
re performance, inspec
t the tires frequently for signs of:
Unev
en wear.
Incorrect
ti
re pressure.
Wh
ee
l imbalance.
Cuts. Abrasi
ons.

B
u
lges (blister).
Ply s
e
paration.
Embedded objects. Impact damage.
Inspe c
tion should be
more frequent when:
Continuo
us high speed op
eration is required.
Ra
pid or extreme temperatures changes occur.
R
o
ad surfaces are rough.
Roads ar
e littered
with debris.
Tread W
e
ar Indicator
•
NO
TE: Tire condition must comply with prevailing local legislation.
New tires must be installed if the wear in dicators are exposed or if there is severe shoulder wear. Shoulder wear is usually
caused by either excessive camber or toe on tires.
T i
re Vibration Diagnosis
A
tir
e vibration diagnostic procedure always
begins with a road test. The road test and the custom er interview (if available)
will provide much of the information need ed to find the source of vibration.
During the road test, drive the vehicle on a road that is smooth and free of undulations. If vibration is apparent, note and
record the following:
The s p
eed at which the vibration occurs.
W
h
at type of vibration occurs in each
speed range - mechanical or audible.
How the vibrati
on is affected
by changes in the following:
- -engine torque
- -vehicle speed
- -engine speed.
Type of v i
bration - sensitivity:
- - torque sensitive,
- - vehicle speed sensitive,
- - or engine speed sensitive.
