My friends 2001 Ram has a problem that has baffled both of us. For some un-godly reason his belt keeps jumping off but, only by a rib or 2 at the AC pully. Now the baffling part is all the pulleys are running true and are not loose. The tentioner has been replace twice as well. Could he have gotten to weak tentioners? After all they are from Napa! Anywho, please, ANY insite or ideas whould be appreciated! Thanks for reading!

 

had a chevy van with this problem i found out after much time measuring and checkin alignments and found that the tensioner was out of align when placed under load. and its gonna sound stupid but i stuck a business card under one corner and the customer hasnt had a problem since. and he has been back for regular service since

 

Thanks very much! We think it might be it but need further investigation before going with a different tentioner yet again!

 

I had that happen and it was the damper pulley the rubber had warn out. ED

 

I had the same issue, replaced the worn belt with a new one from napa, it jumped off all the time. Replaced the idler pulley, still jumped off. Could not figure it out. Went and bought another belt from dodge ($70.00), put it on, does not jump off any more.

Don't ask me why...

 

Check the AC compressor hub for the clutch bearing going out. The clutch will run true when engaged but may wobble when disengaged.

 

mine squealed on shut down bought the gator belt and it stopped my boy bought a different belt always squeals on shut down. No jumping off though.

 

That may be it! It's weird but, at one point the damper and pulley looked like it was wobbling a tad and now it's not at all. Hummmmm Does anyone know where to get a decent damper? Ley me know! Thanks alot guys!

 

Well, gentlemen (and ladies) The new damper worked!!!! $180 from a International dealer and we're in buisness! Thanks to all!
