Jaguar Problems

Persistent Coolant Loss Due to Small Leak at Coolant Reservoir

The plastic coolant reservoir is prone to leak. The reservoir can mysteriously lose coolant or coolant may pool under the engine compartment. If this occurs, the coolant reservoir should be inspected for cracks. If leaks are neglected, the reservoir may fail and cause the engine to overheat.

Plastic Timing Chain Tensioners May Fail and Cause Engine Damage

On this V8 engine, timing chain problems are very common. Because the timing chain tensioners were made from plastic, they can fail prematurely and cause serious engine damage. A noticeable engine noise while idling or during a cold start can indicate a timing chain tensioner problem. The engine noise may also be accompanied by a rough or uneven engine idle. Improved components are available to remedy this problem.

Transmission Failure Common

Premature automatic transmission failure is common. Diagnoses of the fault will be necessary to determine if repair or replacement is the proper repair.

I have a 1990 jag xj6 Sovereign bought for 800 from a guy who collects older cars. I must say I love it, it is my baby! It has never failed me, a bit pricey but we'll worth it. Do all mechanic work myself oil changes, tune ups, etc. Did some restoring to the inside but it is MINT!
Engine get warm maybe the SAE 5 30 is too thin for the engine. My coolant tank had to be replaced as the float stopped working. The car drinks the engine oil too and also consumes the coolant. Catalytic converters went bad (2400 parts + 500 labor + 150 diag). I was covered in the Federal Emissions warranty of 70,000 miles and thus lucked out. CATS system fault which is a cheeky suspension fault...
