85020085 Volvo FMX D11B Water Pump

This water pump serves as a critical component within the engine cooling system, ensuring the continuous circulation of coolant between the engine block and the radiator. By maintaining consistent fluid flow, it prevents engine overheating and ensures stable operating temperatures during heavy-duty cycles.

This part is specifically engineered for Volvo FMX trucks featuring the D11B engine. It is also compatible with various Volvo FM models, including the FM 300, FM 340, FM 360, FM 380, FM 390, FM 400, FM 430, FM 440, and FM 480 series. This ensures reliable performance across a wide range of heavy commercial vehicle applications.

For optimal performance, technicians should inspect the pump during routine belt service. Checking for signs of coolant leakage from the weep hole or unusual bearing noise can help identify potential failures before they lead to engine damage. Always ensure the mounting surfaces are clean and use high-quality gaskets during installation.
