21284318 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 and the radiator to maintain optimal operating temperatures. Built with high-strength components, it is engineered to withstand the rigorous thermal cycles and mechanical stresses typical of heavy commercial vehicle operation.

Compatible Volvo vehicles and engines

This specific unit is compatible with Volvo FMX models including the 380, 420, 460, and 500 variants equipped with D13K engines. It is also fitted to Volvo FM trucks such as the FM 380, FM 420, FM 460, and FM 500 models. The component is designed to meet the strict requirements of heavy-duty engine cooling requirements.

Installation and maintenance guidance

For optimal performance, technicians should inspect the pump and associated belts during routine engine maintenance. Common indicators for replacement include coolant leaks from the weep hole or unusual bearing noise. Ensuring a proper seal during installation is vital to prevent system pressure loss.

Troubleshooting and selection

Maintaining a functional water pump is essential for preventing engine overheating in construction machinery and tractor units. Always verify fitment against your specific engine serial number to ensure perfect compatibility within the cooling circuit.
