Product Details

Gates Water Pump (Heavy-Duty) line components are built for demanding engine cooling needs and are manufactured with premium alloy materials. Part number 45055HD is engineered as an engine water pump for reliable coolant circulation and OE-quality fit. This part cross-references 945055HD and 2882145 for the same application. If you are replacing a worn pump on Ford F-150 or Ford E-Series vehicles, 45055HD is a direct-fit service part for cooling system repair.

Common Cooling System Issues It Can Address

  • Coolant leaks from a worn pump casting or seal surface
  • Noise from failing pump bearings
  • Reduced coolant circulation from impeller wear
  • Overheating caused by pump performance loss
  • Belt-driven pump service on accessory-belt engines

Installation Notes

Confirm accessory-belt drive configuration before installation. Replace the supplied gaskets and O-rings during service, and inspect the pulley, belt condition, and mating surfaces for wear or contamination. Flush the cooling system if coolant contamination or debris is present, and verify proper fill and bleed procedures after installation.

Quality Assurance

Gates tests each new water pump for seal and bearing function, then performs leakage checks on both the casting and the assembled unit. The result is a heavy-duty replacement built to meet OE-quality fit expectations for cooling system repair.
