Description of Change: A new water pump group is used in the above listed engines. The new water pump group has a stronger pulley which is made of ductile iron. The former water pump group with a cast iron pulley had failures in these applications where the fan is installed on the water pump pulley. In these failures, the water pump pulley came off of its shaft and caused damage to the radiator and other parts.
Adaptable To: The new water pump group is adaptable to all 3208 Engines that have the fan installed on the water pump pulley.
