20920065 Water Pump for Volvo FMX D11K Engines

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine block and the radiator. By maintaining constant fluid movement, it prevents thermal buildup and ensures the engine operates within its optimal temperature range under heavy loads.

Vehicle and engine compatibility

This specific unit is designed for Volvo FMX models equipped with the D11K engine, as well as various Volvo FM series variants including the FM 360, FM 380, FM 400, FM 420, FM 440, FM 460, FM 480, and FM 500. It is a highly reliable replacement for heavy commercial vehicle cooling systems.

Installation and maintenance

Technicians should inspect the pump during routine belt service or when signs of coolant leakage from the weep hole appear. Ensuring proper mounting and checking the impeller stability during installation is essential for long-term durability in demanding environments.

Selection guidance

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