I have a 2000 2.2 s10 and I need to replace my belt tensioner pulley because it's been making noises for the past two weeks. The more you press on the gas pedal, the more noise it makes. Anyways, I finally knew what the problem was couple of days ago. This week I'll replace it and buy a new one.
Tensioner froze, causing serpentine belt to come off. Power steering failed, battery light came on, engine began to overheat
