T make a long story short I have a 1988 mercury grand marquis colony park wagon. It onl has 50,000 original miles. Not a bad car, but ever since we changed the alternator, the belt began squeaking badly. Then we realized that the belts were bad, and we replaced the belts.
Soon, it started squealing again as the new belt got broken in and loser. We kept tightening up the alternator, because it was coming from that belt {and that was really the only thing we could tighten up}, but now the alternator is tightened all the way and it keeps squealing. It only happens when it is cold and you have too many things on, like the radio and the headlights on at the same time, with the heat.
The car is power everything, and I don't think its the alternator {Its a regular 65 amp alt. not a high charging one.}. I bought some belt conditioner, but I have to spray it on every day for it to stop squealing.
Any ideas on how to fix it without getting a new belt?My Car Belt Keeps Squealing??
The belt tensioner for the alternator is messed up. Change it. What's happening is that the belt keeps getting elongated because the tensioner is causing the belt to drag and the belt will fail again shortly because of this. A new one doesn't cost much or get it from your junk yard.My Car Belt Keeps Squealing??
misalighned beltMy Car Belt Keeps Squealing??
either your belt is a tad too big, or one of your pulleys are misalighned.
