21969188 Volvo FMX D13K Water Pump

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 consistent flow, it prevents overheating and ensures the engine operates within its designed thermal parameters, which is vital for the longevity of heavy-duty drivetrains.

This specific unit is designed for Volvo FMX models, specifically catering to the D13K engine variants. It is also compatible with several Volvo FM series models including the FM 330, FM 450, FM 410, and FM 370 to ensure precise fitment across various heavy commercial vehicle applications.

Installation and maintenance

For workshop technicians, it is recommended to inspect the pump housing and mechanical seals during routine cooling system maintenance. When replacing this component, it is best practice to check the condition of belts and hoses to prevent premature wear of the new assembly.
