|The XJ40 Sedans began life in March 1987 (as an
88 USA model) and continued until 1997. They carried several different model monikers over
the years including XJ6, XJ6L, XJ12, and XJ12L, as well as having "upscale"
models, the Sovereign, Majestic and Vanden Plas. The "XJ" was used again
for continuity between the XJ40 and earlier Sedans. The 6 or 12 is the number of
cylinders of the Jaguar motor. The "L" cars were lengthened to provide
more room in the back seat. The cars were also split into two different Series by
|The following table lists the starting
VIN (vehicle identification number) for a model year.
The VIN is
typically located on the driver's windshield pillar or the driver's door or jam. On
USA cars federal law specifies that it be permanently affixed in the dash area. Jaguar
cars have a plate that is riveted to the windshield (roof) post on the driver's side.
(Gray market cars usually have a metal tag glued to the dash pad). Additionally this
number is stamped into the RH fender brace or cowl brace and finally it is on the door or
door jamb (by the hinge on early sedans, lock striker on XJS) on a embossed label. All
three should match - be cautious if they do not. The label is often painted over but
usually you can still read it. This is where the build date, i.e., 8/79 will be found.
Earlier Sedans have a metal plate with engine, transmission, body information stamped in
it that is riveted to the fender well. European cars have a 2 x 3" label with similar
information under the hood. The color and trim codes are usually found on 1980->
stick-on labels with the VIN.
Engine numbers are used for all types of parts - gaskets, Lucas,
flywheels, hoses, fuel parts, ignition, and especially water pumps. What will really throw
you a curve is "What kind of ignition do you have" when you order XJS floor
mats! The engine number for an XJ6 is on outer edge of bellhousing flange of block
where it meets the transmission. Ten o'clock position if viewing the motor from the rear.
It is visible when you peer past the brake booster on the driver's side. Example
8L25468. The V12 is a bit harder because it gets dirtier - located on the
bellhousing flange at 12 Noon - take a torch (English for flashlight).
