Madarawolf 0 Report post Posted February 11, 2015 I have a 2002 Chevy Malibu. It worked great until I was rear ended last year. The condition has been deteriorating since. Anytime I press on the gas there is a loud squealing noise and it is really slow to get up to speed. Also, I can't get it to go over 55 mph on level ground. What could be causing this? I have already tired replacing the belt and the idler pulley. Quote Share this post Link to post Share on other sites
Elite_Deforce 1 Report post Posted February 12, 2015 Are you running on all cylinders? Is this the 3.1L V6? The loud squealing could be a water pump, alternator, other accessory belt, anything, but not being able to do 55 sounds like your engine is on its way out.

I'm mostly trying to find out if replacing it will help with my other problems. I'm not sure about my engine, I'd have to check. Quote Share this post Link to post Share on other sites
