85003708 Volvo FM Water Pump

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 a continuous flow, it prevents overheating and ensures the engine operates within its ideal temperature range, even under high load conditions common in heavy commercial vehicles.

Compatible vehicles and engines

This component is specifically fitted to 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 also compatible with Volvo FM13 engines featuring the D13B designation.

Installation and maintenance

For optimal performance and engine longevity, technicians should inspect the pump during routine belt service. When replacing a water pump, it is standard practice to check the condition of the belts and seals to prevent future leaks or bearing play. Ensuring a clean seating surface during installation is vital for maintaining a secure connection to the engine block.

Troubleshooting and selection

Monitoring for signs such as coolant leaks from the weep hole or unusual mechanical noise can help prevent serious engine damage. Consult your authorized distributor for further assistance.
