3801418 Water Pump for Volvo FM Engines

What does a water pump do?

This water pump plays a critical role in the engine cooling system by circulating coolant between the engine block and the radiator. Built with high-strength components, it is engineered to withstand the rigorous thermal cycles and mechanical stresses typical of heavy commercial vehicle operations.

Compatible Volvo models and engines

This component is specifically designed for use in Volvo FM models, including the FM 480, FM 440, and FM 380, as well as various other configurations like the FM 340 and FM 430. It is also compatible with Volvo FM9 engines, such as the D9B series. The part ensures precise flow rates to prevent engine overheating during heavy-duty tasks.

Installation and maintenance

For optimal performance, technicians should inspect the pump during every coolant system service. When replacing the pump, it is recommended to check the condition of the drive belts and gaskets to ensure a leak-free installation. Proper mounting ensures that the impeller maintains correct flow within the cooling circuit.

Troubleshooting guidance

If you notice coolant leakage from the weep hole or increased mechanical noise from the engine compartment, it may indicate that this water pump requires replacement to prevent further system failure.
