My truck has developed a squealing noise. It sounds like it is coming from the serpentine belt, but the noise goes away when I ride the clutch. I would think it is the throwout bearing, but my limited experience with manual transmission hydraulic actuated clutches makes me think the noise would start when I ride the clutch and lessen with no pressure on the pedal.

Has anyone encountered similar noise?

Thanks in advance for any help

 

I had a squealing noise at the serpintine belt and it would come and go. Found out that it was the belt tensioner. I took it apart and put some grease and a small squirt of oil on the pully and no more noise. But with yours going away when you ride the clutch I don't know if that is the problem

 

I am having what I thought was a belt squeal but my buddy doesnt think so. It starts when I start the engine in the morning and gradually lessens over about 45 minutes. I looked at the water pump and see no signs of rust. Doesnt act like an alternator squeal. Belt looks good. It has a new belt tensioner on it. Anyone else have any ideas?

 

Hmmmm...now the noise is lasting longer before it stops. Guess I'll just slap another serpentine belt on it and see if that helps.
