Default Strange belt noise

I bought a certified 04 accord coupe and the belt makes a whinynoise when i hit 4-5000 rpm in 1st and 2nd gear. I'm guessing it's from the alternator belt.. Is it normal to make that kind of a sound? Btw, the car has 45K+ miles.

Maybe try checking the belt tension. I think there are belt dressing sprays to help stop belt slip.
Are the belts old and dirty or newish and clean?

Check the belt tension, but don't overtighten the belts. That can overload the bearings in the alternator & AC.

As the belt gets old, it can get hard & slippery, maybe without developing cracks. If the tension is correct but it slips, try belt dressing. That stuff tends to be only temporary, but it can help you prove that the noise is caused by a slipping belt vs. some other problem.

No, it's more like a high pitched noise. and its worse when the AC is on.

If the car is certified, can't you have the dealer fix it for free?
