85020130 Compatible Water Pump — Volvo FMX

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 consistent flow, it prevents overheating and ensures the engine operates within safe thermal limits even under heavy-duty loads.

Compatible vehicles and engines

This component is specifically designed for Volvo FMX models equipped with D13K engines, as well as Volvo FM models including the FM 330, FM 450, FM 410, and FM 370 variants. It provides a reliable fitment for these heavy commercial vehicle applications.

Installation and maintenance

Technicians should inspect the pump during routine belt service, checking for any signs of coolant leakage from the weep hole or unusual bearing noise. Replacing the pump alongside the timing belt or alternator belt is recommended to ensure long-term system integrity and prevent unplanned downtime.

Troubleshooting and replacement

Check the compatibility list to confirm fitment for your specific engine configuration.
