Question about 1999 Chevrolet Tracker

What makes the fan belts squeal?

Had the timing chain snap in Oct, got it fixed then after driving the car for approximately 6 weeks, the serpentine belt snapped. Replaced it & it, or the other belt, not sure which, has been squealing like mad. It's enough to make me crazy! What causes them to squeal & how do I stop it? I have the smaller belt to replace, but had to buy a special metric wrench to get it in there. Thank you!

New belts need to be readjusted as they stretch unless you have a spring loaded belt tensioner.

Could it be the pulley on the AC that's squealing? Use a mechanic's stethoscope to locate the squeal. If it is the AC, you can get a belt that is shorter, and bypass the pump, since it doesn't work anyway. Try some belt dressing first. When the engine is running, just spray it on the inside of the belt.

You can remove the belt and check each pully 1 at a
time, and make sure they spin freely. Wiggle each
pully from side to side to make sure they're tight and
no loose bearings. Also before you remove the belt,
start the engine and check by eye to see if the belt is
running true, and not misalligned by a bent pully.
One more thing you can try before removing the belt.
With the engine cold start the engine let it run for
about a minute or two, turn it off and carefuly touch
each pully and see if one of them shows eccesive
heat. If one of them is a bit to hot, that's usually the
one causing the problem. Hope this helps.

Either an idler wheel or the tensioner bearings are busy disintegrating, You need to get this attended to immediately before they go completely and cause serious damage or leave you in the lurch.

What if the fan belt break while driving

Dan h described what would happen if your timing belt/chain broke.. fortunately the consiquences aren't as dire if your SERPENTINE belt snaps. Most vehicles have the following systems or devices powered by the front engine accessory drive belt (FEAD belt)
AC compressor
Power steering pump
Fan (some vehicles do and some don't)
Water pump

All but one of these things can be lived without, at least for a short time. If your belt snaps and your water pump stops your engine will overheat in no time flat., say you're cruising through a rural area and your belt snaps a mile and a half away from the next town, your car will get you there, but you had better turn it off once you get into town. After a belt snaps you've got 2 miles before you absolutely need to shut your car down to avoid damage.

Check the serpentine accessory drive belt and the drive belt pulleys for out of alignment issues. Also make sure the belt tensioner is functioning correctly.

How to tighten the tensioner on a 2006 nissan frontier. My truck had a sweaking belt for about a year. I was told that my belt was glazed and needs to be replaced. $95 later no sweak for two weeks and it...

I am assuming you are talking about a fan (or serpentine) belt. If you spent $95 to have it fixed two weeks agoa I'd go back and tell them it is not fixed and ideally they will give it another go for free. Squealing fan belts can be a royal pain. First thing is to check to be sure all the bolts that hold the various brackets for the different components (water pump, alternator, air conditioner, power steerig pump and thensioners) that the fan belt run on are tightened, There is a product called belt dressing that can give you (usually it is only temporary) relief. The fact the squeal stopped for two weeks and is now back does not make me think the problem is the tensioner. The squeal should never have gone away had it been the tensioner. It is possible it was the tensioner and it took two weeks to reglaze the belt but that is nbot likely.
