20995158 Volvo FM 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 steady flow, it prevents overheating and ensures the engine operates at its ideal temperature, even under high-load conditions common in heavy commercial vehicle applications.

Compatible vehicles and engines

This component is specifically designed for Volvo FM trucks, including models such as the FM 400, FM 360, FM 340, FM 380, FM 440, FM 480, FM 300, FM 390, and FM 430. It is also highly compatible with Volvo FM13 engines featuring the D13A engine code.

Installation and maintenance

For professional technicians and fleet managers, it is recommended to inspect the pump during routine belt service. Signs of failure often include coolant leakage from the weep hole or unusual bearing noise. Ensuring proper installation helps prevent serious engine damage caused by thermal fluctuations.

Troubleshooting and selection

Maintaining a robust cooling system is essential for long-haul durability and engine longevity in heavy-duty trucks.
