Re: WHAT IS THE LIKELY CAUSED OF A LOUD SQUEALING NOISE...
100% serpentine belt, don't do what I did and have a "she'll be right" attitude towards the noise and end up stuck on the side of the road and fixing it in the rain.. Go get her fixed immediately, it could last 6 months but for peace of mind, fix it asap !!
I learnt the hard way... Never again.. lol :-(

If it is a squealing sound when you start up or water splashes in that area you need to adjust the tension or replace the belt. If the noise is actually coming from the pulley it may be the bearings on that alternator being bad.
It sounds like your water pump is going it usually vibrates throughout everything if it was your alternator it would show signs with your power the easiest way would to take your belt off remembering the belt route and spin the alternator pulley and the water pump pulley to see if they spin freely without 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.
