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. It is built with high-strength components to withstand the continuous thermal cycles and mechanical stresses typical of heavy commercial vehicle operation.

Vehicle and engine compatibility

The unit is compatible with various Volvo FM models, including the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430. It is also fitted to Volvo FM9 variants such as the FM 9/340, FM 9/300, FM 9/260, and FM 9/380.
