The V6 L series engine uses a timing belt, which must be replaced every 100,000 miles.
The 4 cylinder Saturn engines use a timing chain that typically does not need replacement until you have a reason to remove the cylinder head.
It has a chain that should last the life of the engine.
Yes, it uses an internal timing "CHAIN", not a belt. The timing chain should last until the engine needs to be rebuilt.
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.
The 2004 Saturn Vue 2.2L Engine Uses a Timing CHAIN. It is Much better than a belt, and for 2004, Saturn fixed the issue with poor oil pressure on the timing chain and they last much longer than their predecessors.
A timing chain should last the life of the engine. Timing chains are INSIDE the engine and as such are constantly oiled. By the time the timing chain and/or tensioning mechanism is worn out, it's about time to rebuild the engine.
Yes. The timing chain is INSIDE the engine and is constantly bathed in oil. Under normal conditions it should last as long as the rest of the engine.
Generally speaking, if you have properly maintained and not abused the engine, the timing chain should last until the engine is worn out. If you find that you have any burned valves, by all means replace the timing chain, pulleys and chain tensioners. But a timing chain is not like a timing belt. A belt will wear out after 80K to 100K miles. The chains do age, but since they are constantly in an oil bath, if you've kept the oil clean the chain should last a long time.
Timing BELTS are outside the engine, run dry, and have no external lubrication. Timing BELTS should be replaced according to the manufacturers schedule. But the SL2 is not equipped with a timing belt, it uses a timing chain. Timing chains are internal, well lubricated, and designed to last as long as the rest of the engine. You shouldn't need to replace the timing chain until you rebuild the engine.

a timing chain last longer than a timing belt... a lot longer.
