belt SP 1

Pulleys Required
Using short water pump pulleys, the alternator belt will normally run  in the inner grooves of the water pump and crankshaft pulleys. While not as common, single groove crank and water
pump pulleys may also be used in alternator applications. Factory steel pulleys are available from Chevrolet or from us.

Pulleys Required

Short water pump power steering applications are normally driven off the outer third groove of the crankshaft pulley. If using factory steel pulleys, an add on third groove pulley part number 3751232 will be required. This add on pulley can be attached to a one or two groove crank pulley. The power steering pump will require a one groove (V-8) pulley. Factory steel pulleys are available from Chevrolet or from us.
