21468471 Volvo FM Water Pump

What does a water pump do?

A water pump is a critical component of the engine cooling system that circulates coolant between the engine and the radiator to maintain stable operating temperatures.

Vehicle and engine compatibility

This water pump is engineered for heavy-duty applications, providing consistent flow to prevent overheating in demanding environments. It is specifically designed for use in Volvo FM series trucks, including models such as the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430. It is also compatible with the Volvo FM13 D13C engine series.

Maintenance and replacement guidance

To ensure proper performance and longevity, technicians should inspect the pump for signs of coolant leaks from the weep hole or unusual bearing noise during routine maintenance. It is recommended to check the pump integrity during belt service intervals to avoid sudden engine overheating caused by impeller wear or seal failure.

Troubleshooting and selection

Maintaining a stable thermal environment is essential for heavy commercial vehicle engine longevity. Consult your authorized distributor to confirm exact fitment for your specific chassis.
