20451516 Volvo FM D13K Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, specifically designed to circulate coolant between the engine and the radiator. By maintaining constant fluid motion, it prevents overheating during high-load operations common in heavy commercial vehicle service.

Vehicle and engine compatibility

This component is engineered for compatibility with Volvo FM series trucks, including models such as the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430 equipped with D13K engines. It is built to withstand the rigorous thermal cycles of heavy-duty engine environments.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine belt services. When replacing the unit, it is recommended to check the condition of the drive belts and gaskets to ensure a proper seal. Maintaining correct coolant levels and inspecting for leaks at the weep hole can prevent premature failure.

Preventative maintenance

Regular maintenance of the cooling system helps avoid severe engine damage caused by overheating. Consult your authorized distributor for more information.
