So for spring break we got in my grand prix and drove from Minnesota to Colorado straight through (16hrs, 1000 miles). My car (2000 Grand Prix GTP, 83k miles) is now making nasty whining noises from the pulleys on the left side of the engine. I know one of the noises is the supercharger coupler, which was making a little noise before and now is worse. I'm not sure where the other noise is coming from though. It whines when you accelerate from a stop or turn, so I'm thinking power steering pump or a combination of that and a tensioner bearing... What is the most likely to go wrong at around 80k miles in that grouping of pulleys?
thanks
