21468471 Volvo FM 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 and the radiator. By maintaining steady flow, it prevents overheating and protects internal engine components from thermal stress during heavy-duty operation.

This part is specifically designed for 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 Volvo FM13 engines featuring the D13A engine code. Check the compatibility list.

Installation and maintenance

To ensure proper installation, technicians should inspect the mounting surfaces and verify that the drive belt tension is correct. It is highly recommended to inspect or renew the pump during routine timing belt or alternator belt service intervals to prevent unexpected failures due to bearing wear or seal degradation.

Troubleshooting guidance

If symptoms such as coolant leaks from the weep hole or unusual bearing noise occur, immediate inspection is required to avoid potential engine damage.
