i have a loud squeeling noise coming from under my hood. it goes away if i spray some wd40 on the tensioner pulley but i've already changed the tensioner and idler pulley. all i can figure is the tensioner arm but it sounds like a rotational squeel. anyone else deal with this already?
squeeling noise help!

Change the belt?
hmm if uve already changed the tensioner and idler pulley then start looking at the alt and a/c comp. It coudld be the bearing going bad in one of those man.
I have same problem dont know what the hell it is let me know too please
Good luck with that
my old 97 did the same thing too its only when its chilly though in warm weather it stops
change the belt than reevaluate and use a long screw driver or a stethoscope to listen for the noise if it still present
I had the same problem. I just replaced the alternator, idler pulley, and the tensionor and pulley. I would throw on a new tensionor. I had the same exact problem and the new tensionor stopped the squealing. Funny thing, it only squealed when it was cold. The new tensionor solved that problem. Now I hear more aggravating noises!
Are you still looking at picking up the tensioner arm from me?
I had no noise coming from it when I removed it from my car.

Was there any changes to the front accesory drive system around when this started?
First thing I would do is check pulley alignment between the crank pulley and all the other grooved pulleys. Use a straightedge and a caliper to compare all the other grooved pulleys to the crank pulley.
If the pulleys are not aligned close enough, the 6 v shaped ribs end up meeting off center and "skidding" down the pulleys ribs as it runs. Basically like a constant belt burnout. :burn:
In my case, my belt noise started when a new shortblock was installed. For some reason, some tolerance stackup allowed the balancer to install to far on. I made a shim that I installed on the crank that spaced the balancer out enough to put it in-line.
After that, try a new belt but not before you fully clean and scuff all the pullies, ribbed and smooth to deglaze them.
