i know this might sound obvious and you might have already tried it but try spraying all of the pullys and belt accessories with a little wd-40 or whatever you like to use. when ever i start a vehicle up that i haven't ran in awhile sometimes the belt will squeal really bad and a little lubrication clears it right up.

I had a squeal on my pickup I changed the tensioner and the idler pully too ,2 new belts from (advanced auto) .Then I went and bought a belt at napa and that fixed it.Yup I was pissed then. I also tried that spray the belt trick it hardly ever works on a serpentine belts on the old v-grooves it worked but nomore.

the quallity of the belt Will make a differance. i had the same squeel problem, thought i had a bad pulley, so i inspected all of them and found that the belt had alot of weather check on it, so i went to my local parts store and picked up the cheapest one i could find. BAD *&(^$ choice. it squeeled worse than the one i had, so then i got a gates and no more squeel.

yeah i paid more money but when it comes to belts,,, just get a good one.

You didn't change the belt? It probably didn't have anything to do with the tensioner... Belts can crack, which you can easily see. But sometimes they just glaze and they will slip on the smooth idler pulley or tensioner pulley. The pulleys themselves can get belt rubber melted to them and will cause a squeal. I would check all of your pulleys for debris and such, especially the smooth ones.


By the way - WD-40, belt quiet, stop squeal, or any other crap in a can will not fix your belt, ever... When have you used a lubricant to keep something from slipping?

99 whitelightning: Here is an old mechanic trick for squeeking belts. Take a little dielectric grease and put it on the underside of the belt. It will instantly stop you squeeking sound if it is from the belt. It works like a champ every time.
