The GM 2.2L (not ECOTEC) engine for that model year used a timing chain with a Teflon tensioner. As far as I know, it had no belt. However, the tensioners are notorious for failure...they break off and get between the chain and the sprocket, which snaps the chain. When this happens, the valves contact the pistons, bending them. If the engine is starting to sound like a diesel, you should consider having the chain and tensioner replaced.
