How to set the timing chain for a 1995 sl2?
I am assuming you already have the timing chain off the vehicle, and you are looking for the timing marks. if not, please note, there is no manual adjustment on the timing chain. I have included a picture of the correct timing placement on my website http://thecommi.angelfire.com/index.html under Timing Chain. I hope this helps you.
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.
Is there an adjustment that can be made easily if the timing chain is rubbing on the upper chain guard of a 1998 Saturn SL2 1.9L?
No such thing as a timing chain belt. It is either a belt or chain. Replace the belt according to the schedule in your owner's manual. If it breaks and your engine is an interference engine, you will 95% of the time have damage. You will know the extent of the damage when the engine is torn down. The 1992 SL2 has a timing chain. Mine has 240,000 miles on it and is still running…
