The timing chain is designed to last the life of the engine and is normally only replaced during a complete engine rebuild.
Pontiac Grand Prix does not have a timing belt. It has a timing chain and it is replaced when it breaks.
A timing chain will normally last the life of the engine and is replaced during a complete engine rebuild.
Technically you are supposed to replace the timing belt or chain every 60,000 miles. It is a costly expense to replace it so often but it can be far more costly if you don't. Since your vehicle has a chain the pieces can wear down and eventually break and shoot up into your engine causing catastrophic engine failure which can completely ruin your vehicle.
It does not need to be changed unless it fails.
I looked for an answer to this question in my Haynes manual and found nothing about how often to change the timing chain. It DOES, however, to into great detail about how to do it. FriPilot simply because they dont have a timing chain on the 2.2 ecotech
Hopefully, never. I have 3 Jeep Grands with 253K, 203K, and 167K - none has needed a timing chain yet - all V8s.
There is no recommended replacement interval given for the chain replacement timing belts are critical, chains are not.
80,000 ---100,000
Timing chain usually needs to be replaced each 180-200K miles.
never
the 2001 does not have a timing belt,instead a timing chain,which does not required replacement as often as belt
The chain will last the life if the engine and does not require changing.
