Probably a glazed belt...

I'd start by replacing the belt, and while the belt is off, spin the tensoiner pulley with your hands and feel for bearing roughness. If the pulley bearing runs rough, replace the tensioner along with the belt.

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.

Squeal under hood 2000 Pontiac Grand Prix GT (3.8 L)


I would start with a belt. While removing it feel how much tension the tensioner has on it, on the 3800 egnine they have a stiff tensioner(sorry I don't have any specs for how much) After you get the belt off you can look at all of the pulleys and spin them to see if the bind or look for stuff stuck in the grooves on the pulleys.
It sounds to me like the belt is streched. I would not recommend one of those gator back belts, they seem to make more noise sooner than a good v notch belt. But thats just my opinion!

I have a terrible whinning noise under the hood of my 95 f-150 300-6 and it is not the power steering pump, I have already changed that


Check the idler pulley that holds tension on the belt...sometimes the bearings go out and you'll get a squeal... coud also be the alternator ... also check for vacuum leaks...open the hood while it's running and see if you can narrow it down to the location of the noise..
A great tool is an extra long screwdriver... you can put one end on different components and carefully put your ear to the handle end and you'll get an amplified sound from that component...this can help you located the noise source..

Just replaced belt and alternator. Engine squeals very loud when started. What should I check next? belt tension seems good.


Sounds like the new alternator was run without first fully charging the battery (12.3 - 12.8 volts)
This will destroy an alternator every time -- the classic symptom is a squealing belt.

Loud squealing noise


The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.
