Well to tight a belt...and could just be old, that is the weak spot IMO, you can change everything to heavy duty and to cog or 10-12 rib...the waterpump pulley cant be changed

In a blown, or high horsepower application, you need to weld the water pump pulley directly to the shaft.

looking directly at the pump (where the shaft comes through the pulley) drill some indentadions with a 1/4" drill bit at the seam of the pulley and shaft. Fill the spots with weld, and you wont have any more problems, quick and easy fix.
