most timing belts are under plastic covers located on the front of the engine they are not internal ie like a timing chain that is lubricated by the engine oiling system.
Yes, it uses an internal timing "CHAIN", not a belt. The timing chain should last until the engine needs to be rebuilt.
The engine will stop and other internal parts

Timing Chain. Internal. $600 labor to open the engine plus parts kit at around $350.
A timing chain is not the same as a timing belt. Timing chains do not generally need replacement unless you are rebuilding the engine. While a timing belt is simply a ribbed, flat fanbelt that wears and can become weakened with age, a timing chain is oiled constantly and should be expected to last the life of the engine. Like other internal engine components, a timing belt is affected by the condition and quality of your engine oil, and as such, should last as long as the other internal engine components.
this engine has a belt drive timing system
Yes, if there is internal leak.
If the engine is an interference engine, yes, you can have internal engine damage if the belt is installed incorrectly.
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.
For a total refill, the system holds 6 quarts. And it has a timing belt, not a chain. If you have 1.6 L engine, a timing belt. If the 1.8 L engine, a timing chain.
