Squealing noise I get a loud squealing noise when i crank up. It last for about two minutes then stops. Occasionally it will start squealing while im driving as soon as i turn heat off the noise stops

If it is a manual gearbox, check the thrust bearing.

serpentine belt is getting old and hard and the cold weather was causing it to slip
check belt condition ( small cracks across the grooves = scrap and get a new one) and check tension

What is causing that irritating noise? ' DSMtuners

Most new cars come with ceramic disc brake pads to reduce noise. Aftermarket brake pads, depending upon materials in them, can be prone to squealing. Some pads come with adhesive shims that are designed to absorb vibration and reduce or stop squeal. There is also a compound you can but to put on the back of the pads to do the same thing when you install. Sometimes the noise will go away once the pads have had a chance to settle in .Some are just ornery and won't shut up.

Try to tighten the belts a little firm.Sounds like when engine idling no squelling only when about to take off .Some times belts may seem ok on the outside but if you look on inner side you tend to see cracks in the belts .

Have you checked the power steering?

Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.

check to see if the power steering pump is binding do you have the defroster on when this happens? if so it maybe the a/c compressor turn the defroster off and try to start it .

Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

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.
