When we bought our latest pre-owned car, (a 1994 Saturn) the drive belt would squeal LOUDLY for about 30 seconds when the car was cold. After that, it would quiet down. So, I changed the belt to a brand new one. Guess what? It's still doing it! Always during the first 30 seconds or so after starting the car in the morning.
Why would the belt squeal if it's brand new? I've checked the tensioner and all the pulleys the belt runs to, and none of them squeal when they are turned...so what gives? It has to be the belt...but it's a new belt!
Help!

It is perfectly normal when the tempature is cold for a squeal to happen. There are sprays that you can use to reduce and even eliminate the noise. You can find it anywhere from Walmart to automotive stores. When the weather is cold the rubber (or whatever flexible material it is made of) is much less flexible therefore increases it's resistance to move. the fixed pulleys will slip against the belt and make the noise. the spray keeps the belt very flexible at a wide range of tempatures
I hope this helps

Sometimes the pulleys have a glaze on the contact surface from the old belt slipping. You can treat it with belt dressing or put just a little dab of toothpaste, not gel, on the belt. The abrasive action of the paste will eliminate the glaze. Hope this helps.

It's the moisture that accumulates when it sits over night. Nothing to worry about, but just darn annoying. You could try spraying some STP belt dressing on it.

I would say the tensioner is bad, not putting enough tension on the belt.

I agree with Bullitt.... your pullys get glazed, especially form an old hardened belt, your new belt will slip on that pulley.

Yep, probably the tensioner. But if that aint it, could be a pulley, too.
