Remove the serpentine belt and check the belt and pulleys for damage. While the belt is off, turn the alternator by hand listening for the noise.

Possible problem with the alternator. Could be source of the noise if it's bearing is going out.


On Lexus ES 300 Pulley that is located beside the engine and is on the serpentine belt with the alternator is sqealing what is the problem?

If you're describing the idler pulley or the tensioner pulley, it's probably a bad bearing. Pulley bearing failure is common and relatively easy to repair. Remove tension from the serpentine belt then turn the pulley back and forth with your fingers. It should make no noticable noise and should turn smoothly. If you can hear any grinding noise or if the pulley feels like the bearing is grinding, replace it.

How do you identify which pulley to replace on 97 Saturn sl?

To diagnose a noisy pulley, remove the serpentine belt and turn all pulley's by hand. Try to notice which of the pulleys make a grinding sound or feels loose. Even an alternator bearing can sound like just another bad pulley bearing, so don't assume that the alternator is okay. A bad bearing often feels like there are little grains of sand inside when you turn it manually, but sometimes it's difficult to detect the problem if you haven't had the experience. Note, before you remove the serpentine belt, make certain that you have some kind of drawing or a good mental image of the routing so that you can put it back.

Why is your alternator belt continuing to break and snap on your 97 Mazda Protege?

I am having the same problem with a 99 Protege. I have changed the alternator and aligned/cleaned the pulleys and the problem persists.I replaced the alternator, on my 1997 Mazda Protege, seven times before someone figured out why the serpentine belt kept breaking. It was the belt tensioner! It had to be removed and rebuilt. Now it is working like a charm!! And I havn't had to replace the alternator in over 3 months!!!!

What causes a squeaky alternator and how can you fix the problem on a 96 Chrysler town and country?

A squeaky alternator is sometimes a sign that the fan belt or something associated with it is squeaking, not the alternator. (Possibly the belt or belt tensioner) So first I'd make sure it's actually the alternator squeaking before I proceeded. You could try some belt dressing on the belt and see if that helps or changes the squeak. If however it is the alternator, that's usually a sign the bearing's gone out and you will need to replace the alternator.

Can a Serpentine belt problem cause an engine stall or power steering problems?

Yes. Have had this happen to me. A serpentine belt is what brings power to both your alternator and your power steering pump. If the alternator isn't turned by the belt, it can't produce electricity, and your engine will stop. If the power steering pump isn't turned by the belt, it can't move fluid, and your power steering will quit working (note that you can still steer in an emergency, but it's VERY tough). Hope this helps. NJM
