3801418 Volvo FMX Compatible Water Pump

What does a water pump do?

This water pump plays a critical role in the engine cooling system by circulating coolant between the engine and the radiator. By maintaining a consistent flow, it prevents overheating and ensures the engine operates within its optimal thermal range during heavy-duty service.

Compatible vehicles and engines

This component is specifically designed for Volvo FMX trucks equipped with D13K engines, as well as various Volvo FM models including the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430. It provides reliable performance in demanding environments.

Installation and maintenance

For optimal maintenance, technicians should inspect the pump during belt service intervals. It is recommended to check for signs of coolant leakage from the weep hole or unusual bearing noise. Replacing the pump alongside the timing belt or alternator belt can prevent unexpected engine overheating.

Troubleshooting and selection

Ensuring correct fitment is vital for system integrity. Always verify compatibility with the specific engine code to ensure the internal diameters and flange dimensions match your requirements.
