I Recently but a new belt on are 2001 Ram 2500 Cummins and went on with out a problem. The belt squeals really bad from about 1500-3500Rpms i sprayed a little bit of belt conditioner on it and it seemed to help for a little bit what could be making the belt squeal so much??

 

better watch out you don't get a ticket for that!

 

Make sure the new belt has the same amount of groove's. And belt dressing is a no no. Get some carb cleaner and clean the belt and the pulleys. Use a wire brush to clean the grooves of the pulleys. Also make sure the tensioner is notfroze up and moves all the way back and forth.

What brand belt?

 

The belt is a Gates FleetRunner-Serpentine Belt. The belt has the same number if grooves and the tensioner is fine and i cleaned the pulleys with a wire brush and Ether.

 

Assuming you checked all the pulleys for noise and free spinning, that's all I got.

 

Would taking the belt off and cleaning it fix it or just wait and see if the squeal goes away after the belt brakes in a little?

 

I'd take it off and clean everything again. That stuff sucks.

 

The belt is either too long, or the tensioner is going belly up.

 

Ya no kidding but i cant stand the squeal it pissis me off on the other hand i dont drive it everyday

 

Get back under the bridge please!
