Question about 1996 Isuzu Trooper

96 Trooper still squealing after changing all belts

We changed all three belts in the Trooper which for awhile was ok. Now, the squealing is louder and longer than before we changed them. It will squeal for about 15 secs then stop. If I turn on the air/heat it will squeal for about a few seconds then stop. It doesn't squeal any other time EXCEPT if it is raining. Then, it will squeal when I downshift or sometimes when I stop then go. We have tried tighten the belts, putting dishsoap on them - nothing is working. Any suggestions?

    So, I should take back the alternater belts and get new ones, is that what you are suggesting? Just want to make sure coz these are suppose to be new.

    We just needed to have the belts tighten again. We were told that they will start to squel after replacement as they will stretch so you need to have them retighten.

Sound like alternater belts you changed one may not have been as good as it should try again

    can you adjust and make the gears fit tighter into the belt so in a since it's like you are taking a rubber band and holding it loosly with two fingers on different hands, to obviously tighten it you pull your fingers and hands apart and thus it is tighter, right now your trooper is holding it loosly not sure which belt but the alternater belt is always a good bet(I have had these squeel on several different cars and trucks) they are notorious in my book for squeeling, although you said you have three you replaced so it could be any of them with the motor running the hood up you should be able to watch and listen and even possible watch it slip if it is the alternater it should be a fairly easy to tighten, on most cars and trucks, even tractor trailer(big trucks) look for 1 or 2 bolts that are connected to the arm that holds the alternater or the gear where the belt goes to should have atleast 1 bolt that has a grove it rides in that when loose it easily slides in that bolt is the one that will tighten and loosen the belt. Sorry I couldn't get back to you sooner went out of town. let me know if this helps Thanks and good luck goofballlovers

Makes squealing noise

The squeal would be the alternator slipping on the belt. I would think either the newly installed belt is not the correct length, or the belt tensioner is no longer doing its job properly.

I have a 2004 Chevy silverado1500 truck, with a chirping now kind of squealing serpentine belt, I changed the belt the idler pulley and belt tensioner it worse for a day after I change something then comes...

If you replaced the belt,tensioner and pulley then you have "glazed" a pulley. There are 2 very easy fixes to try. The first one is to hold a bar of soap on the under (grooved) side of the pulley while the vehicle is idling. Obviously extreme care is required while doing this. If that doesn't get rid of the squealing, spray carburetor or brake cleaner on the under side of the belt while it's idling. That should do it.

Could be the alternator .
A Battery store could test your car's battery and alternator to determine if the alternator is working correctly and that the cars battery is ok as well.

Squealing noise (LOUD)

You need to check the pulley alignment of all the pulleys, they should all be in a perfectly straight line, otherwise the belt will squeal

2002 Mercury Cougar Squeal

Just for testing, a few seconds, will the vehicle start and run w/o the belt? Have a helper work the throttle, is the sound gone? If problem not the belt, check the belt driven accessory. Sometimes you can use a long metal rod of some kind, with belt on, one end of the rod touches accessory housing, the other end goes on that bone behind your ear, helps to magnify the sound. I guess you could use a mechanics stethoscope to do the same thing. Have helper work the throttle while you listen to each. Don't get tool or anything caught in belt. This is a serpentine belt, I haven't looked?
Maybe an accessory trying to freeze up or bad bearing? I can't think of anything else at the moment?

Need belt diagram!

I found these 3000GT/Dodge Stealth DOHC Serpentine belt diagrams on the link below...

If you are re-using the drive belt, be sure to install it in the same orientation as it had before removal (same side facing the wheel well). Insert the belt from above. Turn it "sideways" to fit it in between the alternator pulley and the AC pipe. Correctly tension the drive belt using its tensioner pulley. Before installing the plastic covers and wheel, temporarily install the IC pipes and battery negative cable and start the engine to check the belt operation. If the belt squeals it is either misaligned or too loose. I found that my old belt squealed when installed "backwards" from how it was removed. It did not squeal when installed in the same orientation. If you have messed with both drive belts, spray a little water on one belt at a time to see which is squealing. A misalligned belt will stop squealing for a very short time after water is sprayed on it, but the squealing quickly comes back louder than before. If the belt is loose, the squealing will immediately get louder. Also note that there is just a little play in how the alternator bolts in. If misalignment is a problem, loosen all four bracket mounting bolts (this may require again removing an IC pipe), reposition the alternator, and tighten the bolts to see if this helps. Do not tighten the belt too much because this can lead to shaft bearing failure over time.

Here are some links concerning drive belt adjustment.

Car is squealing and whining in front of engine. Can you help?

It sounds to me as if your serpentine belt and/or belt tensioner is bad,
I had a similar problem on my s10 and replaced belt,idler & tensioner.
All three pieces ran about $80.00. I did the work myself. Hope this helps.
