I bet the belt is also cracked and should be replaced before it fails most cars have a tension bolt you tighten to tighten the belt, and when removing the belt simply loosen slide the old off stay aware of routing and then slip the new on tighten to specs
It sounds like you have a worn or streched belt making the sqeeling noise. Whenever you turn on a
device in the car that draws a fair amount of voltage
ie. a/c or headlights it will cause increased drag on
the alternator and if you have a loose/worn or glazed
belt, it can slip around the pully making the squeel.
To adjust the alt-a/c belt loosen the mounting bolts
on the tensioner, then use the adjuster bolt behind
the tensioner pully to loosen and tighten the belt.
Be sure to check the belt for cracks bald spots etc.
While the belt is loose spin the pullys to make sure
they all spin freely. Also I would replace the belt just
to be sure. Hope this helps
One or all belts aren't tightened enough.
The squell is a belt slipping.
It does it in gear because there is more drag then.
Smelling rubber either because they are new belts, or the belt is way to loose.
There is no adjustment on newer cars they use a spring loaded tensioner wheel that keeps constant tension on the belt. When the belt starts squealing on cars as the electrical accessories are turned on the belt must be replaced it has worn out and is slipping.
Most likely your alternator belt is a little loose. My daughter's car did that right after I changed the belt, The new belt stretched a bit, and a couple weeks later, it was sqealing. I tightened the tensioner up a bit, and it stopped. I has now been quiet for months!

sounds like to tightened the belt to much... back off the tension on it a little bit, with the belt, you want it tight, but not to tight,,,, it should have about 1/4 flex in the belt when tightened... make a little loose and see if you still have the squeel... if you still do try going to a parts store, like pepboys, autozone etc. pick up some brake cleaner it will be in a canaster, and while the engine is running spray a little <spirts> on the pullys, and see if the squeel stops, if so then it could be a bad bearing in the part... see what makes it stop... the brake cleaner will dry quick and not ruin anything cause you do it in short bursts do not use wd40 or any oil type of stuff on it cause it will cause slippage...
You Need to Replace the Belt Tensioner for this Repair. Until then you can go to the Local Auto Parts Supply and get a Can of Fan belt Dressing, This will make it Quite for a while. Spray it Right on the Belt and Pulleys. Please Rate My Response! Thanks!
