22479364 Volvo FMX D11B Cooling System Water Pump

What does a water pump do?

This water pump serves as a vital component within the engine cooling system, specifically designed to circulate coolant between the engine and the radiator. By maintaining a steady flow of coolant, it prevents overheating and ensures the engine operates within its intended thermal range during heavy-duty service.

Compatible Volvo models and engines

This component is compatible with Volvo FMX models including 380, 420, 460, and 500 variants featuring the D11B engine. It is also fitted to Volvo FM series trucks such as the FM 380, FM 420, FM 460, and FM 500 models. These parts are essential for maintaining the reliability of heavy commercial vehicle engines.

Installation and maintenance

For professional technicians and workshop owners, it is recommended to inspect the water pump during routine belt service. Replacing the pump alongside the timing or alternator belt can prevent unexpected failures caused by bearing play or seal wear. Always verify compatibility with specific engine configurations before installation.

Troubleshooting and selection

Monitoring for signs such as coolant leaks from the weep hole or unusual mechanical noise can help identify potential issues before they lead to system failure.
