85003708 Volvo FMX D11K Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, facilitating the continuous circulation of coolant between the engine block and the radiator. Built with high-strength components, it is engineered to withstand the rigorous thermal and mechanical stresses encountered in heavy commercial vehicle applications.

Vehicle and engine compatibility

This part is specifically compatible with Volvo FMX models, including variants such as the 480, 440, and 400 equipped with D11K engines. It is also fitted to a wide range of Volvo FM series trucks, including the FM 300, FM 340, FM 360, FM 380, FM 390, FM 400, FM 430, FM 440, and FM 480 models.

Installation and maintenance

To ensure proper function and prevent overheating, technicians should inspect the pump for signs of coolant leakage from the weep hole or unusual bearing noise. It is recommended to check the pump's condition during scheduled belt replacements to prevent unexpected system failure.

Troubleshooting guidance

Maintaining the cooling system integrity is essential for engine longevity in construction machinery and tractor units. Regular inspection helps avoid issues like cavitation or impeller wear that can lead to sudden temperature spikes.
