525.03.0026 Water Pump Housing compatible with Volvo and Renault

What does a water pump housing do?

A water pump housing serves as the structural foundation for the coolant circulation system, ensuring the pump impeller remains perfectly aligned to drive fluid through the engine block. This component is essential for maintaining stable operating temperatures under heavy loads and prevents overheating in demanding commercial vehicle applications.

Compatible vehicles and engines

This housing is compatible with several heavy commercial vehicle models, including Volvo FH12, FH13, FH16, FM series, VNL, and VHD, as well as Renault Trucks Kerax, Magnum, and Premium. It is specifically designed to support high-performance engine codes such as the Volvo D13, D12, and D11 series, along with Renault DXi11, DXi12, and DXi13 engines.

Installation and maintenance

When replacing the housing, technicians should inspect the mounting surfaces for any signs of corrosion or warping to ensure a leak-proof seal. Proper installation of this high-strength component prevents coolant loss and maintains the integrity of the entire cooling circuit during long-haul operations.

Selection guidance

Selecting a housing built to OE tolerances ensures that the water pump operates within its intended mechanical limits. For optimal performance in heavy-duty engines like the Volvo TAD1341-1345VE or Mack Granite MP7/MP8 series, verify that all gaskets are replaced during assembly to prevent pressure drops.

OE cross-reference

525.03.0026 (Water Pump Housing Water Pumps) is the equivalent of the Renault Trucks and Volvo OE numbers. This part directly replaces Renault Trucks OE number 7420825534. It also replaces Volvo OE numbers 20397805, 20825534.
