Thread: Timing Chain/Belt replacement? Tension-er replacement?

2000 Grand Prix GT @ 210,000


I am wondering if my engine has a timing belt or a timing chain and also if I should replace it. I figure if it's a chain it will last much longer than a belt, but I am at 210,000 miles so won't it wear and stretch eventually? Also I know that the tensioners wear down over time, should I replace that?

If it's not making noise, leave it alone. These motors can go well into the 200K range and beyond on a stock chain. If it ain't broke, don't fix it.

If you haven't ever changed the LIM gaskets on that motor, then now would be a good time before it lunches the motor from eating coolant. Only then would I suggest a timing chain AND gear replacement since you are almost there during the LIM gasket job.
