22479364 Volvo FMX D11K 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. By maintaining consistent fluid flow, it prevents overheating and ensures the engine operates within safe thermal limits under heavy-duty conditions.

Vehicle and engine compatibility

This component is specifically designed to fit Volvo FMX models including the 380, 420, 460, and 500 variants equipped with D11K engines. It is also compatible with various Volvo FM series trucks, such as the FM 380, FM 420, FM 460, and FM 500 models.

Maintenance and troubleshooting

To ensure long-term reliability, technicians should inspect the pump for any signs of coolant leakage from the weep hole or unusual bearing noise during routine maintenance. It is recommended to check the pump's condition whenever the timing belt or alternator belt is being serviced to prevent unexpected engine downtime.

Selection guidance

Maintaining a stable cooling cycle is essential for the longevity of heavy commercial vehicle engines. For precise fitment verification, consult your authorized distributor.
