3801102 Volvo FM D11B 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. By ensuring a continuous flow of coolant, it prevents overheating and maintains stable thermal conditions during heavy-duty operation.

Vehicle and engine compatibility

The component is specifically designed for Volvo FM series trucks, including models such as the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430. It is also compatible with Volvo FM11 units equipped with the D11B engine.

Maintenance and installation guidance

To ensure longevity, technicians should inspect the pump during routine cooling system maintenance or when replacing belts. Monitoring for signs such as coolant leaks from the weep hole or unusual bearing noise can help prevent engine overheating. Check the compatibility list to ensure correct fitment for your specific engine configuration.

Troubleshooting and service tips

Maintaining a stable cooling circuit is essential for fleet longevity and minimizing downtime in heavy commercial vehicles.
