CAN A ALTERNATOR MAKE A SQUEALING NOISE

1998 Pontiac Bonneville • 240,000 miles

I change my water pump and the tension pulley when I start the car up I hear a chirping noise but when I rev it I hear a squealing noise it sounds like its coming from the alternator I can hear it when im driving

Belt is slipping causing noise. May need new belt and/or tensioner.
