85003708 Volvo FMX/FM Water Pump Equivalent

What does a water pump do?

The water pump is a critical component within the engine cooling system, responsible for circulating coolant between the engine and the radiator to maintain ideal operating temperatures.

Vehicle and engine compatibility

This water pump is specifically designed for Volvo FM series (including FM 480, 440, 380, 340, 300, 400, 360, 390, 430) and Volvo FMX series (480, 440, 400) equipped with D13K engines. It serves as a high-durability solution for heavy commercial vehicles requiring consistent thermal management.

Installation and maintenance guidance

For optimal performance, technicians should inspect the pump during routine belt services. Monitoring for signs such as coolant leakage from the weep hole or unusual bearing noise can prevent overheating and potential engine damage. Proper installation ensures the impeller and mechanical seals function correctly under high engine loads.

Troubleshooting and engine protection

Maintaining a robust cooling system is essential for the longevity of heavy-duty engines used in construction and long-haul transport. Consult your authorized distributor to check the compatibility list.
