89 SEDAN - ALTERNATOR BELT

1989 Cadillac Deville

My alternator belt (S or Serpentine) started making a strange higher-pitched noise yesteday when cruising at about 65 mph. When I pulled over and popped the hood with it running it sounded like something was rattling. The belt looks fine and is moving fine and no service lights illuminated the dash. I drove it home another 50 miles with this condition. Could it be that the belt needs adjusting?

It's most likely the belt tensioner but could also be any of the other items run by the belt.
