Model Years Affected: 2000, 2002

Engines Affected: 3.0L V6, 4.0L V8

Average Mileage: 64,682 mi (6,600 mi - 92,000 mi)


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.

    made a strange noise while in park idling shhut motor off for 10 minutes tried to restart and no-go both tensioners broke during start up and chains stretched (I know how does metal stretch?) dealerships will rape and violate your ass, but they have the parts and tools to do the job. good luck.
