What could be making a squealing noise??

Asked by Feb 10, 2014 at 08:22 AM about the 2003 Chevrolet Silverado 1500 LS Extended Cab 4WD

Question type: Maintenance & Repair

I have a 2003 Chevy Silverado 1500 4WD. It started making a loud squealing noise at idle and then giving it gas would make it
get even louder. I have changed the water pump, fan clutch, belt tensioner, idler pulley, power steering pump, and the belt and
it still is making a squealing noise but it doesn't get louder anymore when giving it gas. What else can I check or do?

Well looks like you attacked quite abit. Check the altenator and the A/C clutch pulley.

Checked alternator and A/C clutch and found out it was the A/C belt. I got a new belt and it stopped! Thank you for your help!
