belt squeal! Really annoying need help!!

[GuSpeed]

Hi! When I start my car and drove with the heater on or the button that blow air onto the windshield, it makes this squealing noise in the engine. It's really loud. Sounds like a belt slipping. But I'm not sure what belt and what to do. Please help!

Belt squealing is usually from a belt being too loose for one reason or another. Check the tension on the belts, the loosest one is probably your culprit. If that doesnt work, just start the car and pop the hood.. you'll be able to tell where its comin from..

You will need to replace the belt that has been squealing. Once they start squealing the belt's edges get glazed so you'll never really completely stop squealing just by tightening them up... get new belts, tighten them right, and you'll be all good.
