21814040 Volvo FH Water Pump Compatible

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, facilitating the continuous circulation of coolant between the engine and the radiator. By maintaining stable operating temperatures, it prevents overheating and protects engine integrity under heavy-duty operating conditions.

Compatible Volvo trucks and engines

This component is specifically compatible with Volvo FH series trucks, including models such as the 400, 420, 440, 460, 480, 500, 520, and 540. It is engineered to fit Volvo FH16 units equipped with the D16K engine. These parts are built to withstand high temperatures and vibrations common in heavy commercial vehicle environments.

Installation and maintenance guidance

For optimal performance, technicians should inspect the pump during routine belt service. Monitoring for signs such as coolant leaks from the weep hole or unusual bearing noise can help prevent sudden engine overheating. Proper installation ensures the impeller and mechanical seals function correctly throughout their service life.

Troubleshooting and selection

Selecting a high-strength component ensures that the cooling system maintains consistent flow rates even under maximum load. Consult your authorized distributor to confirm exact fitment for your specific engine configuration.
