3801102 Volvo FM Compatible Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, ensuring the continuous circulation of coolant between the engine and the radiator. By maintaining a steady flow, it prevents overheating and protects internal engine components from thermal stress during heavy-duty operation.

Compatible Volvo vehicles and engines

This unit is specifically engineered 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 FM13 engines featuring the D13A engine designation. This ensures precise fitment for various configurations within the heavy commercial vehicle segment.

Installation and maintenance

For workshop technicians, it is recommended to inspect the pump during routine belt service. Replacing the pump alongside the timing or alternator belt is a best practice to prevent unexpected downtime. When installing, ensure the sealing surfaces are clean to maintain a proper seal against the engine block.

Troubleshooting and inspection

Monitoring for symptoms such as coolant leaks from the weep hole or unusual bearing noise can help identify early signs of failure. Maintaining a robust cooling flow is vital for the longevity of heavy-duty engines used in long-haul and construction applications.
