85020085 Volvo FH Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine and the radiator. High-strength components ensure that the pump maintains consistent pressure and flow, even under the demanding thermal loads typical of heavy commercial vehicle operations.

Vehicle and engine compatibility

This specific unit is designed for Volvo FH models, including FH4 and FH5 series, specifically compatible with D13K engines. It is also fitted to other Volvo FH variants such as 400, 440, 480, 500, and 520 models. For exact fitment, verifying the engine code and OEM reference is recommended.

Maintenance and installation

To ensure proper function, technicians should inspect the pump for signs of coolant leakage from the weep hole or unusual bearing noise during routine maintenance. When replacing this component, it is professional practice to inspect associated belt systems to prevent premature wear of the new unit.

Troubleshooting guidance

Maintaining a stable cooling environment is essential for preventing engine overheating and ensuring the longevity of heavy-duty truck engines in tractor units and construction machinery.
