Depends on miles on the engine - I traded in a 95 SL1 with 206,000 miles with the original timing chain still on the engine. My impression is that under normal circumstances, you should get at least 175,000 miles on a Saturn timing chain.
The Saturn sl2 does not have a timing belt, it has a timing chain. And under most conditions it does not need replacing.
You are correct that the SL2 uses a timing chain. However, since it uses a timing chain it does not need to be replaced as does the timing BELT. In general, a timing chain should last the life of the engine.
Always replace the timing chain, sprockets and tensioner rails whenever you remove the head.
I believe you need to replace a timing belt. Cause it uses timing chain which doesn't required to change as timing belt.
It has a timing chain that does not need service.It has a timing chain that does not need service.
Unless you have other problems, you should only need to change the timing chain whenever you rebuild the engine or remove the head or have other needs to take the front off the engine.
you don't need to replace the timing chain until it becomes noisy
Timing chain, no. Timing belt, yes.
It is not necessary to change timing gears when changing a timing chain unless they have become worn. You won't know if this is the case until you get the cover off and inspect them. It is necessary to change any chain tensioners when you change your timing chain.
Timing chain. You do not need to change it, ever.
do i need to change the timing chain on my bmw x5 its done 118000
Typically a timing chain does not fail since it runs in an oil bath. Of course, any physical component of a vehicle CAN fail, but timing chains typically do not need to be replaced until you rebuild the engine. A good general rule is, replace the timing chain whenever you work on the valve assembly.
