The SC dampener/pulley are notorious for wearing out and spinning within itself as the rubber gets old. It's been discussed many times.

it could be both, or it could be the belt.

If the belt is dry and cracked then it's the belt, problem solved (might be a good idea to go ahead and do the timing belt as well).

If it's the crank pulley, it would squeak and you could get a nasty vibration when you get on the gas. The rubber dampening material can fall apart over time.

If it's the tensioner, then the belt will feel loose and flexes easily when you move the belt up and down by hand. it should feel tight at all times.
