Joe, Replace the belt and do the following. Prior to installing the new belt check to be sure that the alternator pulley rotates freely by hand, next install the new belt. Check to be sure that the belt is not making contact with any of the alternator attachment bolts. Be sure not to over-tighten the tension on the belt. After your adjustment push down on the belt midway between the alternator and water pump pulleys, Minimum deflection should be no less than 1/2 inch. Possible causes of your belt failure could be over-tensioning. If the belt is too tight it could overheat and disintegrate. It is also possible that you may have a defective belt. If the belt was purchased from us will be happy to send you a free replacement.

After I put my Delco alternator back in (had to get a bolt tightend and voltage regulator replaced) I noticed a squealing noise comming from the engine when the alternator was under heavey load (A/c max blower 4) It would only make this noise in idle or low gears. When I took the car to the Alternator repair shop to ask what they though the noise was, the man assured me that it was not the Alternator, but that the belt was not tight enough. Sure enoguht, I got a crow bar, tightened the belt, and had no problems for the rest of the day. The next morning I got the same noise. The belt felt loose again, but the tensioner was still at the same place. I tightened it to max and the noise went away that time as well. Last night, I was driving home, and all the sudden, my voltage went to 0, and as I was turning on my road, I watched my temperature guage rise like a rabbid jack rabbit. I made it home on a GUll-wing and a prayer, immediately shut off the car, and watched the gallons of coolant and smoke spew out. After it cooled down I went out with a flashlight, and noticed that there was no Alternator/Water pump belt. I also noticed a lot of black dust by the belt drive pulley. ( where the belt was suppsed to be)I had noticed this black dust before, when the belt was there, but paid not attention to it. The belt did not simply fall off, it disintegrated. What caused this to happen? I was a new belt. Thanks Joe Palatinus VIN 17167 6808 [Non-text portions of this message have been removed]
