21814009 Water Pump for Volvo FH Series

What does a water pump do?

This water pump plays a critical role in the engine cooling system by circulating coolant between the engine and the radiator. Built with high-strength components, it is designed to withstand high temperatures, vibrations, and long service hours typical in heavy commercial vehicle operations.

Compatible Volvo vehicles and engines

This component is specifically compatible with Volvo FH models (including 420, 460, 500, and 540 variants) and Volvo FH16 engines equipped with the D16E engine. It serves as a reliable replacement for original equipment parts to maintain thermal stability during demanding tasks.

Installation and maintenance

For proper maintenance, technicians should inspect the pump during belt service intervals. Common indicators for replacement include coolant leakage from the weep hole or unusual bearing noise. Always ensure the mounting surfaces are clean and gaskets are correctly seated during installation.

Troubleshooting guidance

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