85020085 Volvo FMX Compatible Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, ensuring the continuous circulation of coolant between the engine block and the radiator. By maintaining consistent thermal regulation, it prevents overheating and protects heavy-duty engine components from thermal stress during demanding operations.

Compatible Volvo vehicles and engines

This part is designed for compatibility with several Volvo vehicle models, including the FM series (FM 300, 340, 360, 380, 390, 400, 430, 440, 480) and the FMX series (FMX II 330 to 540, FMX III). It is also fitted to Volvo FMX III LNG variants. This ensures reliable performance across diverse heavy commercial vehicle applications.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine cooling system maintenance. It is recommended to check for signs of coolant leakage or unusual bearing noise. When replacing this unit, it is best practice to inspect the associated belts and gaskets to ensure the integrity of the entire cooling circuit.

Troubleshooting guidance

Proper selection ensures that the engine maintains its operating temperature even under high thermal loads. Check the compatibility list to confirm fitment for your specific vehicle model.
