Water Pumps

79 Products
Shop direct-replacement semi truck water pumps — matched to your engine to stop overheating with an exact, drop-in fit.

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
