 J84/01 January 1984, Introduction of the Model 9520 Radio.


In February 1984 the model 9520 Radio was introduced. The radio featured a removeable front control panel. The radios were shipped in two parts, with the chassis installed at the factory, and the front installed at the dealer.

If there is a problem with the radio, the first check is to replace the control panel with a known good unit. This determines whether the fault is with the panel or the chassis of the radio. It is suggested that the faulty part be replaced.

The tape player had a fault.... If it were set in tape scan mode, the tape couldn't run at fast forward or rewind. So in order to fast forward or rewind on a blank section of tape, the tape scan control had to be turned off.

The control and chassis numbers were both to be supplied on a card in the back of the owners manual. The Sound System Registration Card was requested to be sent in by the new owner.


 J84/02 January 1984 Sill Drain Holes


There are four body seal drain holes on each side of the XJ6. To suppress water from being splashed into the two front holes, they were plugged beginning with VIN 362000. The drain holes that remain should be checked yearly for clearance.


J84/03   January 1984     Spark Plug Gap

The correct spark plug gap for the XJ6 is listed at 0.035 in. , and the XJS  HE at 0.025 in.

J84/04   February 1984   Water Pump Time Revision

A change in the time it takes to replace the water pump was changed to 2.45 hours due to the addition of the air pump.


J84/05   March 1984   Engine Oil Consumption   XJ6


A change was made to a former bulletin issued in September 1983. Detailed procedures were given to deglaze the cylinder bores without dismantling the cylinder head.... this bulletin also advises that the valve guide oil seals on the inlet valves should be replaced. The repair time for this operation is listed at 19.40 hours.


J84/06   March 1984    Jaguar Radio    All models

The new radio will not interchange with the previous model... there was a change in the wiring harness to accommodate for the new models power requirements.
