21814040 Volvo FMX D13K Water Pump

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine and the radiator to maintain optimal operating temperatures. By ensuring consistent flow, it prevents overheating and protects engine components from thermal stress during heavy-duty operation.

This component is specifically designed for Volvo FMX models equipped with D13K engines, including various configurations such as the 380, 420, 460, and 500 variants. It also provides fitment for a wide range of Volvo FM series trucks, including FM 360, FM 380, FM 400, FM 420, FM 440, FM 460, FM 480, and FM 500 models.

For professional workshop technicians and fleet managers, inspecting the pump during routine belt service is recommended. It is essential to check for signs of wear such as coolant leaks from the weep hole or unusual bearing noise to prevent sudden system failure. Maintaining the integrity of the mechanical seal and housing is vital for long-term cooling efficiency.

Consult your authorized distributor to ensure correct application.
