I'm speaking from experience and I have two stories about belts. I had a 90 honda accord and I had a belt problem as soon as I changed my alternator and belt. Been to several mechanics and tried everything and the belt still squeeled.I got OEM,smaller,tightened to the max and nothing work.Turns out the squeel was coming from the AC compressor.I didn't have AC so I by-passed it by using a shorter belt.Problem fixed.
I installed a light weight pulley and the noise started as soon as I turned the ignition.I had to go three belt sizes smaller from the one recommend to solve my problem.So try not to over tighten the belt,try using a smaller belt so that you don't over tighten it

This isn't an astrophysics problem. The solution is very simple...you just need to be a better diagnostician. With a little experience, you'll notice that these cars are a piece of cake.

There is absolutely NO reason to get a smaller sized belt unless you are running different size pulleys or bypassing the a/c compressor.

I understand you were just trying to help...but there is so much bad info on this site that it can be really hard for newbies to learn anything.

ALthough I agree that the FSM with the deflection figures is a good way to do it, I don't know about you but its hard to measure EXACT deflection down there. Squealing already tells you what the problem is, your belts slipping so you obviously have it too loose. Tighten it up to factory specs and see if it stops. It should GL

BTW, it isn't THAT hard to measure the deflection with a small ruler. (using metric, because it IS hard to read the small differences in inches)

I gave the 2 experiences for him to consider,not do it.We can't be both right bacause we gave two different opinions.Isn't that the reason for the org in the first place?I'm just saying "if it's tightened to the max" like mine was you might want to "try a smaller" belt.Good luck on the fix though

To put this thread back on topic...
1) there are 2 belts on the car, have you diagnosed with one is actually causing the squeal?
2) make sure they are snug.
3) if the noise is still there, remove the belts and rotate the pullys by hand. You might have a tight or failing bearing on one of the belt driven components.

I'd like to add another thing to njmaxseltd's list of things to check.
With the engine running, look at the harmonic balancer on the crankshaft. If it looks like it is wobbling, it needs to be replaced.

I gave two points,one being if it's tightened to the fullest you might want to try a smaller belt,because like me I went to several mechanics to have it checked and it turned out to be the AC compressor.
I gave the 2 experiences for him to consider,not do it.We can't be both right bacause we gave two different opinions.Isn't that the reason for the org in the first place?I'm just saying "if it's tightened to the max" like mine was you might want to "try a smaller" belt.Good luck on the fix though

njmaxseltd and DennisMik are giving out some good advices there.
