4.0L Supercharged V8 - XJR Performance
Petrol
Check this by gently pressing the brake pedal while cruising at 80km/h. | Description: It's worth feeling for any vibration in the steering wheel or pedal, as the XJR's front suspension bushings can experience wear over time, often resulting in a shimmy.
While driving, pay close attention to the transmission shifts under light and heavy throttle. | Description: In cars of this age, ensure the gear changes feel smooth and seamless; any hesitations or 'flaring' could suggest the transmission fluid is due for a service or that the gearbox is reaching a point where internal attention may be needed.
Check this by turning the engine on and listening to the cold start sequence. | Description: It is quite common for the timing chain tensioners—specifically if they are the original plastic-bodied units—to eventually warrant an inspection or upgrade to the later metal-bodied style to ensure long-term peace of mind.
Check this by operating the air conditioning and heater controls through all zones. | Description: The blend door motors are known to occasionally become temperamental; observing how the climate system reacts can give you an indication if any calibration or repairs might be helpful down the line.
Usually the time to evaluate the condition of the suspension dampers and upper control arm bushings for optimal ride comfort.
A sensible interval to confirm the health of the cooling system components, including the water pump and thermostat housing.
A good opportunity to have the supercharger oil levels and drive belt tensioners inspected by a specialist.
Check the coolant reservoir for any signs of discolouration or oil contamination.
Ensure the transmission fluid has been changed, as this can extend the life of the ZF gearbox significantly.
Inspect the underside of the vehicle for any signs of fluid weeping from the rear main seal or differential seals.
Verify the service history specifically for records of timing chain tensioner replacement.
Test all electronic features, including the central locking and seat adjusters, to ensure the modules remain responsive.
Estimated repair costs if issues arise
If the previous owner hasn't updated these to the metal-bodied versions, it is a prudent piece of preventative maintenance to consider. It involves accessing the front of the engine to ensure the timing system is secure.
To keep that signature 'Jaguar ride' feeling sharp, you might eventually need to budget for a refresh of the front and rear control arm bushings as the rubber compounds age over the years.
Depending on the car's history, you might eventually need to budget for a full transmission flush and filter change to keep the shifts crisp and protect the internal gearsets.
