I don't mean to change the subject but this is the closest thread I could find. Here's the story...
My serpentine belt started to shear off so I had it replaced the next day with no problems. The only changes since then have been that Today I had a shop replace my muffler w/the superturbo from dynomax and add a stainless exhaust tip. When I got back to work I disconnected the battery to reset the computer. When I went to reconnect the battery a buddy of mine noticed that two ridges of the serpentine belt were over the edge of the 'water pump wheel' closest to the engine block. We moved it back into place and started the engine; only to have it jump back on the bay edge of the water pump. We have replicated this process two or three times and taken it for a test drive. During te test drive two ridges sheared off the belt. It's at my mechanics shop and will be examined tomorrow morning...where I will watch them examine the vx. I hope things are ok and the belt was faulty or something of that nature.. Also, my mechanic pulled the diagram for the belt and it was routed correctly.. Any ideas guys?!
