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.

The automatic transmission oil is synthetic and Jaguar claims it never needs changing. However, to prolong the transmission life, our technicians strongly recommend changing the automatic transmission oil at 60,000 miles.
Use only Jaguar-approved fluid and carefully follow the Jaguar instructions for refilling the transmission.
