21221878 Volvo FH 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 helps the engine operate at its ideal thermal state even under high load conditions.

Vehicle and engine compatibility

Specifically designed for Volvo FH models, this unit is compatible with various configurations such as the 400, 440, 480, 500, and 520 variants. It is also engineered to fit Volvo FH13 engines, particularly the D13B series. This precision engineering ensures a reliable fit for heavy-duty truck applications.

Maintenance and inspection

To ensure optimal performance, technicians should inspect the pump during routine cooling system maintenance or when replacing belts. Monitoring for signs of coolant leakage from the weep hole or unusual bearing noise can help prevent premature engine damage. Proper installation is vital to maintain system pressure and flow rates.

Troubleshooting guidance

Consult your authorized distributor to ensure exact fitment for your specific engine configuration.
