There are 4 camshaft sprockets that must be aligned perfectly for the engine to function properly, and if the timing is off very far the engine can be completely destroyed.
A special alignment tool is available that holds the camshaft and crankshaft sprockets in alignment while you replace the timing belt and adjust the tensioner pulleys. That's about the only way to properly align the timing sprockets, and the only way approved by the manufacturer.

The Service Manager at a Pontiac dealership will answer that one for you.
Yes.The good news is, the timing chain seldom breaks; they aren't like the timing belts. You can typically just drive the vehicle until the engine is tired, then replace the timing chain, sprockets and tensioner slides while you're rebuilding the rest of the engine.The bad news is, anything is possible and a timing chain CAN break.The "L" series uses a timing belt for the V6 engine, but the 4 cylinder Saturn engines all use timing chains.
The SC2 is an 'S' series Saturn, and all 4 cylinder engines of the S series Saturn's used a timing CHAIN rather than a timing belt.
The 4 cylinder Saturn engines used an "Oil bath" timing chain. The V6 Saturn engines used an "external" timing belt.
The timing belt on a 2000 Isuzu Trooper is replaced by removing the engine accessories, taking off the timing cover and loosening the tensioner. The belt can then be slipped off the sprockets and a new timing belt put in place.
The marks are on the cam and crank sprockets, and on the timing belt. They all must match.
The main causes of backfire in any car are incorrect ignition timing, crossed sparkplug wires or worn timing belt (or chains and sprockets).

You don't - its all done by the PCM (computer). Eric
The V6 engine in a LS2 has a timing belt with replacement intervals at 100k miles
