Hello all, my first visit here. I understand that you guys know your stuff. We share a wonderful engine............I'm the owner of a 2003 c32. Here's my issue/question.

Several weeks ago upon start up my belt sounded like it was squealing a bit. After a few mins it would stop. I checked and found what appeared to be the belt rolling off of the tension pulley. Here is a picture of what I found:

The belt, idler and tension pulley were all replaced w/ parts from the stealer based on cars VIN.

Welp, the tension pulley is doing the same thing, it seems to be about 3/8ths "in" too far. The belt is hanging off the front a bit, just like the first photo. Mind you the belt lines up perfectly and tracks perfectly on all other pulleys and it's not stressed, making noises, etc.

I'm at a loss............were old and new parts wrong? Crank does not appear to be walking as it would effect the belt as it rides on other pulleys. I have no idea what's going on here, any help/suggestions would be greatly appreciated. Thanks all.

Marc
