I was doing some mountain driving and after about the first run my car started making this really loud squeek/shreek noise. It sounds exactly like a belt. When I free rev the car, the belts do not slip at all and no noise. Only underload or driving very hard does it do it. I did a search for the same issue i have but no one has the shreek underload problem. Does anyone else have/had the same problem? Gemme some insight before I tighten my belts to tight or wrong. Thanks

 

get the double sheave alternator pulley for the air pump youo removed.

 

thats the answer to your problem

 

Aye Aye, Will do.

The only other belt I have is the AC belt. (it gets hot here I need my ac) I tightend that up a bit. If still makes the noise, I'll buy the new pulling. Thanks Guys.
