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.

    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

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.

My 96 grand cherokees serpentine belt squeals at startup once in a while then goes away.Is it a pulley possibly seizing?

First, the belt could be loose, because the loose belt does this. Second, the belt could be worn out. A worn-out belt will also squeal, as the rubber will harden and slip. You should be looking at your belt two or three times a year to check for cracks inside, you'll need a strong light and maybe a hand mirror.
The reason it squeals is the alternator is recharging the battery because of the electricity that was removed from it when you started the car.
Be blessed.

Squealing coming from the belt tensioner

It is either your tensioner or your idle pully. You will need to replace them as it could destroy your belt. What is happening is the bearings are bad in the pully causing it to stop spinning and squealing the belt.

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.

Shouldn't be a problem, they were essentially the same truck. Isuzu didn't change anything until 01 I believe.

it is one of youre belts. possibly youre timing belt. (not sure though) the belt itself is bad or you could possibly have oil on one belt. if it started after an oil change thats most liikely what it is. if not just pop the hood and see if any belts are torn, glazy, etc.
