This manual is built around the 1984 Jaguar XJS as Jaguar originally documented it, so the torque values, clearances and diagnostic steps you find here are the ones specified for this exact year and trim rather than a generic XJS reference.
Trims
- Base Coupe 2-Door
Known issues on the 1984 XJS. Three recalls are on federal record for this model year. The first covers the fuel tank assembly, where excessive fuel vapor pressure can build after prolonged cycling and weaken the tank structure, allowing leaks that can lead to a vehicle fire in the presence of an ignition source. The second covers the vehicle speed control system, where dirt entering the electronically controlled valves in the cruise control actuator can keep it from disengaging under normal driving, risking loss of control and an accident. The third covers the fuel injection system's fuel rail, where leakage near the hose and clip fittings can result in an engine compartment fire or destruction of the ignition distributor cap. Owners have filed 5 complaints for the year, and no technical service bulletins are logged for it.
From a fuel rail inspection to checking the cruise control actuator or a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 1984 XJS.
POSSIBLE FUEL LEAKAGE FROM THE ENGINE FUEL INJECTION SYSTEM, PARTICULARLY IN THE AREA OF THE HOSE/CLIP FITTINGS.
A NEW FUEL DELIVERY SYSTEM DESIGNED TO ELIMINATE FUEL HOSE CLIPS WILL BE INSTALLED.
