85003125 Volvo FM Water Pump Equivalent

What does a water pump do?

This water pump plays a critical role in the engine cooling system by circulating coolant between the engine and the radiator. By maintaining constant fluid movement, it prevents overheating during intensive operation. Built with high-strength components, it is designed to withstand the rigorous thermal and mechanical stresses typical of heavy commercial vehicle engines.

Compatible Volvo vehicles and engines

This component is compatible with Volvo FM series trucks, including models such as the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430. It is specifically engineered for use in Volvo FM13 engines with the D13B designation.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine belt service. It is recommended to check for signs of coolant leakage from the weep hole or unusual bearing noise. Replacing the pump alongside the timing belt or alternator belt helps ensure long-term system integrity.

Troubleshooting guidance

Monitoring the cooling system regularly helps prevent serious engine damage caused by overheating or insufficient flow rates.
