85013466 Volvo FMX and 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. Built with high-strength components, it is engineered to withstand the demanding thermal cycles encountered in heavy commercial vehicle operations.

Vehicle compatibility and engine fitment

This component is specifically designed for Volvo FMX models (380, 420, 460, 500) and Volvo FM series (FM 380, FM 420, FM 460, FM 500). It serves as a reliable replacement part to maintain the thermal balance of the engine during intensive transport tasks.

Installation and maintenance guidance

During installation, technicians should inspect the mounting surfaces and ensure the drive belt is properly tensioned. It is recommended to replace the water pump alongside the timing belt or alternator belt as part of routine heavy-duty maintenance to prevent future overheating issues.

Troubleshooting and inspection

Regular monitoring for coolant leaks from the weep hole or unusual bearing noise can help identify potential failures before they lead to engine overheating. Consult your authorized distributor.
