Hi,
Anyone have some ideas why my serpentine belt jumps 1 groove on the crank pulley? I have tried 2 new belts and both did it at only a few thousand miles run-time. It's the 3800 series II VIN K (97 Grand Prix GT).
Car has 73K, at around 40K I had the alternator, water pump, and aircondition compresser replaced. I also replaced the tensioner pulley with a newer model for the last belt hoping for the best--no luck.
From what I've read, I should check pulley alignment and perhaps the harmonic balancer. Since the belt feeds onto the crank pulley from the compressor I'd suspect that pulley first. Are these pulleys really able to be lined up?
Thanks, Chad
