I have a 1997 Sunfire 2.2 that the A/C compressor siezed on. So rather than go to the expense of servicing the ac I bought an Dorman A/C compressor bypass pulley. Here's the problem I run into: The ac compressor bypass pulley has 5 "ribs" the alternator has 4 the ps pump has 4 and the crankshaft pulley has 5 I believe. So if I align the belt to the left the belt wants to fly off the ps pump and the tensioner. If I align the belt on the right side of the ac bypass pulley the belt rides normally on all pulleys and does not rub against the engine, except the crankshaft pulley. It rides on the inside edge of the pulley (closest to the engine) and I though ok at least it's not flying off so I'll drive it this way and maybe it will work itself into it's own grooves and it seemed to be doing that slowly. Problem is now the belt is splitting on that inside edge from the way it's riding the crankshaft pulley. I am at a loss. What is going wrong? It seems that a fraction of an inch either way, wreaks havoc. I should also mention that I have also bought and installed a new tensioner.
Thank you for any help.
have the same problem?
