When I first got my truck the alternator belt was so loose you could just about spin the alternator pulley with the engine OFF.

I replaced both belts and this will be the 3rd time Ive had to tighten the alt belt inside of 6 months. WTF?? Are the parts stores stocking the wrong belt for this thing?

Anybody else had magically loosening alternator belts in their trucks?

not to sound like a dumb question, but... did you tighten both bolts? there is the pivot and the keeper... if you leavee one loose, it could loosen up the belt. just a thought

Yep Im sure I tightened both bolts. The only thing I wish I would have done is marked the adjuster slide to see if its the alternator thats loosening up or if the belt is stretching/wearing. I guess its possible that I havent been tightening it enough

You might want to make sure that the slide adjuster is not loose. I had the same problem and everything was tight and could not figure it out. I finially found that where the slide bolts to the block was missing the bolt. Rebolted it and everything has been fine since.

the parts store buy my house did give me the wrong size it was way too tight my altinater had to be moved as close to the block as possible to get it on, it works but dont just throw away the wrong belt idea
