85000347 Volvo FM/FMX 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. By maintaining a consistent flow, it prevents engine overheating and ensures stable operating temperatures for heavy-duty engines during intense work cycles.

Compatible Volvo trucks

This component is specifically designed for Volvo FM models, including variants such as the FM 480, FM 440, FM 380, and FM 340, as well as FM 300, FM 400, FM 360, FM 390, and FM 430. It is also compatible with Volvo FMX II (including 460, 330, 420, 500, 540, 370, 520, 430, 400, 440, 480, and 380), Volvo FMX (480, 440, 400), and Volvo FMX III (460 LNG and 420 LNG) trucks.

Maintenance and inspection

To ensure reliable performance, technicians should inspect the pump during routine belt service. Common indicators for replacement include coolant leaks from the weep hole or unusual bearing noise. It is recommended to check the integrity of the mechanical seal and housing during every cooling system inspection to prevent sudden thermal failures.

Troubleshooting guidance

Consult your authorized distributor to confirm fitment for your specific vehicle engine configuration.
