Water Pumps Overview
The water pump keeps coolant moving through the block and radiator; a failing pump — bad bearing, leaking seal, or eroded impeller — causes overheating and can strand the truck. Van Horn Truck Parts carries heavy-duty water pumps and gaskets cross-referenced to Cummins, Detroit, PACCAR, Mack, and Automann part numbers.
Match the pump by your engine make and model, and confirm the inlet/outlet and pulley/gasket configuration.
Mechanic & Fitment Specs:
- Match by: Engine make/model, inlet/outlet, pulley/gasket configuration
- Cross-references: Cummins, Detroit, PACCAR, Mack, Automann
- Buying tip: Replace the gasket and inspect the belt/tensioner with the pump
