1986 Jaguar XJS Service and Repair Manual
The 1986 Jaguar XJS factory service and repair manual is built around this exact model year, so the torque figures, fluid specs, and diagnostic steps inside are the ones Jaguar published for your car, not a generic stand-in from another XJS year.

Known issues on the 1986 XJS. Four recalls are on federal record for this model year. Two involve the fuel tank: excessive fuel vapor pressure can build from prolonged cycling and weaken the fuel tank structure, leading to fuel leaks and, with an ignition source present, a fire risk. A third covers the cruise control actuator, where dirt entering its electronically controlled valves can keep the system from disengaging under normal driving, risking loss of control. The fourth covers the rear compartment wiring harness, which may have been installed incorrectly and short circuit, risking an electrical fire. Owners have filed 2 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a fuel tank inspection to a cruise control actuator check or tracing a short in the rear wiring harness, it keeps you on the OEM procedure for your specific 1986 XJS.
EXCESSIVE FUEL VAPOR PRESSURE CAN OCCUR.
THIS CREATES FUEL ODORS AND AFTER PROLONGED CYCLINGCOULD CAUSE WEAKENING OF THE FUEL TANK STRUCTURE,
