As if I need another thing to fix on my most beloved piece of **** ever...now I've got some belt squeal. The serpentine belt is 6 months old, and both the tensioner and idler pulleys are brand new. Although the tensioner itself is getting easier to unspring when I take the belt off each time. I've narrowed it down to either the water pump bearing (because I ran it for 2 months with straight water) the belt being glazed or the tensioner. Last night I poured oil on the belt and it stopped for a little while. Any ideas before I spend money?

 

Also the tensioner will rock back and forth a lil at idle.

 

Spray the spring inside the idler pulley with some WD-40. It helped mine stop squeeling.... just a thought

 

Was it a temporary fix? I'm thinking that the tensioner is slipping

 

Check the center bolt on your harmonic balancer and the bolts that hold the crank pulley on.

 

I had a lower (not the lear loud one of belts going nuts) squeal on my 1997 Ram. Mine did the same thing when I sprayed WD40 on it. The squeal went away for about 5 seconds before coming back. Fixed it last night with a new tensioner arm and pulley.
