Going down the road yesterday ( late 12:30 ish ) and i hear the fwap fwap fwap of a belt jumping ship which struck me as odd because when i did the WP about 6 months ago i did the idler pulley,tensioner and serp belt..

After waiting for a tow finally got the beast home..Come this A.M. i am out there under the hood and the belt is laying the motor with the very last groove next to the engine pulled apart..Its hard to miss how do you pull apart JUST the last groove. Was not cut by anything that looks completely different.

So i checked everything.Nothing is frozen up, the new idler pulley looks a little toasty but thats across the entire pulley not just the inner edge.And again how in the heck do you pull apart just one groove..The back of the belt looks like its been hot,and again across the entire withe of the belt not just the inner edge.

So any ideas.? Anyone ever have this happen.? Going to get another belt and replace it..Want to get ahead of it and find out how the heck it can pull in half just the one inner groove. NOW i KNOW i keep saying that about the JUST the inner groove being pulled apart.IF it had been cut,split or twisted up i would be okay.Both ends of the one groove that snapped are frayed and stretched ...

Just a guess here, but it could be an alignment issue with the pullies.

That is pritty funny, i dont care who ya are!

Perhaps there is something amiss with one of the actual pulleys. Verify integrity. Timing indicator? One time I knew this guy that had a similar problem and turns out he actually had a chunk missing out of his alternator pulley. Just sayin...

Check alignment of pulleys start with any aftermarket pulley or one that didnt come with the setup. I had one from an underdrive for a 4.3 that everywhere says is the same, its not it shredded the last rib of the belt, changed the pulley no problem since.
