Whenever i start my car (cold) my belt squeeks like a madman, and i have to revv it up to stop it, my lights dimm and stuff when it happens so im guessing its the alternator belt. Which is just a V belt if i'm not mistaken, is there an article on how to replace it? or is it pretty self explanatory?

really self explanatory. loosen the bracket, slide it off, then put the new one on. but if i were u, i would just try belt dressing spray first, that usually gets rid of the squeaking and it will condition the belt. u can find it at any parts store.

sometimes it squeels at low rpm b/c its "glazed", so you will have to get a new belt like already suggested.

However, replacing the belt isn't so easy as just taking it off and putting the new one on. I recently replaced my Alt belt b/c it got glazed while i was at the track. Basically if you still have the power steering and AC belts on, you will need to take them off. And to get the the Power steering belt off you need to relieve tension by unloosening the tensioner, then unbolt your lower torque mount on the driver side so that the belt can loop off.

To get the AC belt off, just loosen the tensioner on that and loop it off. To loosen the tension on the Alt belt, just loosen the top bolt that you see on the alterator, and it can swing forwards (towards the front of the car) to relieve tension. Don't tighten the belts too tight, nor too loose. i forget what the specs are, but maybe someone with a helms can chime in.

aftermarket belts will squeal. No question about it. OEM belts are the only way to go. The aftermarket belts will continuously stretch. I tensioned my aftermarket alt belt once a week and it would still squeal horrible.

Your belt might just be loose, there is a bolt on the lower part of the alternator, and one on the upper. The one on the bottom has a slot for adjustment, that is your tensioner. Have someone use a pry bar (or something similar) to hold a decent amount of tension on it while you re-tighten the bolts.

Edit: The tensioner is on the top, not the bottom, my mistake.
