Belt keeps coming off pulleys and shreds. I lost three in the past 5,000 miles. I have replaced. Water pump AND pulley, PS Pump AND pulley, Idler AND tension pulleys. After each replacement, the "new" belt squeels loudly and comes halfway off the A/C compressor until it shreds. I pressed the new PS pump pulley as much as 1/4" past flush with the PS pump shaft, and it is still 1/4" off the A/C pulley. I shimmed the PS pump 1/4" with the pully flush with the shaft, still shred the belt. I just ordered a new PS pump bracket because it looked like the old one "might" be bent by 1/4". With everything removed from the front of the engine, I noticed that the A/C compressor pulley is about 1/2" misaligned to the driveshaft pulley too. There are no adjustments possible to the A/C compressor, but it seems as if IT is the only thing out of alignment. What am I missing? I drove the car for about 5000 miles after first buying it without any belt problems. The only reason I replaced the belt was because I needed to replace the water pump. While I had it torn apart I decided to replace the idler and tension pulleys and the belt. Since then have I gone through 3 belts in another 5000 miles. I'm about to install the new PS pump bracket. Would a couple of pictures of the A/C pulley and driveshaft shed any additional light while I still have a clear view? Do you have any specs on the measurement from A/C pulley to back of A/C compressor that I might compare to what is actually installed?
have the same problem?
