Hey all. I have a 1994 Isuzu Rodeo. The belts squeak real loud. It used to stop after a minute or so, but now it keeps going. This is what I've done:
1. Changed all the belts. - Still squeaks
2. Changed the Water pump. - Still squeaks
3. Changed the alternator. - Still squeaks

What else is there to change? Can the pulley really be that loud?

Thanks.

 

Which motor do you have?

Do your adjustment points still have thread travel left(can you make them tighter)?

If you can tighten them more, do it.
If you are at the end of your tensioners range of travel, You have the wrong belts.

I had this same thing on my Trooper. Parts store gave me the wrong belt.

Is it an actual squeak? or is it a squeal? If it is a constant squeal, it may be a bearing in one of your pulleys

 

This is the 3.2 6 cyl. engine. I have another update- seems like after about 3-4 minutes at idle it stops making noise???
Also, it seems more like a squeal. I will tighten the alternator belt in the morning and see what happens. Thanks for the help

 

It's the belt; I had the same problem. Maybe you got the wrong sized belt. I had them changed by an authorized Isuzu mechanic and he used original isuzu parts. Good luck.

 

OK, I adjusted the belt super tight. so far so good.
Looks like I didn't have to change the water pump and alternator!

 

good
