85000347 Volvo FM 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 to prevent overheating. Built with high-strength components, it ensures consistent thermal regulation even under heavy-duty operating conditions common in commercial transport.

Vehicle and engine compatibility

The unit is specifically designed for Volvo FM series trucks, including models such as the FM 480, FM 440, and FM 380. It is also compatible with Volvo FM9 variants equipped with D9B engines. This ensures precise fitment for fleet managers and technicians looking to maintain specific engine performance standards.

Installation and maintenance

When performing maintenance, it is recommended to inspect the pump housing and impeller for signs of wear or leaks. Technicians should check for coolant leakage from the weep hole or unusual bearing noise during routine service intervals. Replacing this component during belt service can prevent more significant engine cooling failures.

Troubleshooting and selection

For optimal system longevity, ensure all connections are secure and the cooling system is properly bled after installation. Consult your authorized distributor to verify exact application requirements.
