Cant stop belt squealing noise? on 1991 Dodge Spirit

Yes i did everything one can think of doing, cleaned pulleys, checked idler bearing, tightened up so tight noise went away and belt blew after 25 miles...lol. I even sandblasted pulleys, wire brushed, sand paper, you name it i have done it. (belt dressing, candle wax,even a master mech.said spray WD 40 on it) WD40 made it quite for a couple of days and thought he was on to some thing. Going to take to dealership and look for the oldest service man their and see what he says to try?

On my second new belt, no difference, thanks for your time.

Did you replace all 3 belts with a top quaility brand? That should fix it right up. If the correct tension is applied!! Never put 'anything' on a belt but the proper tension! Maybe water would be ok to quiet squeal for testing. That other CRAP just makes matters worse once it wears off! Oh, i have been doing this for 40 + years myself. Hope that is old enough!

That made me laugh, old enough...lol, im 55 and have had more cars than a normal person would even consider. Service tech with Sears for 36 years but always had a love for anything with wheels. Have done every basic trick one can think of but no luck. Tighten so tight it destroyed belt and till it did that was the only time it was silent. I mean i sand blasted pulleys, checked alt.,idler, all ok? I think i will try a dodge replacement belt and if that dosent work it can go into barn with the other autos.

55, well you just a sprout! Lol. Now back to my question, have you replaced ALL belts with a brand name like Dayco, Gates or Goodyear Gatorback? That's all 3 belts. Were you able to get enough tension on the alt. belt, that one can be tough.

Thanks for every ones help...tore it apart again and with straight edge found alternator slightly twisted. Now from tension and age the rubber mounts have twisted. Swap right to left and vice versa and bingo ....no noise. So even a slight angle can cause this problem.Will see if i can buy new rubbers but for now swaping around make it quiet and returned my love for this rust free dodge. Terry
