Just getting the new-to-me truck running, but it has a noisy belt squeal under acceleration or when the rpms are up.

First glance the fan belt is very thin. It matches the groove in the harmonic balanced and the alternator but the groove on the water pump pulley is much larger.

I'll get a pic soon but I take it there are several pulley groove widths out there?
