23959585 Compatible Water Pump for Volvo FMX

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. High-strength components ensure that the impeller and shaft maintain consistent flow rates, preventing overheating even under high thermal loads.

Compatible Volvo trucks and engines

This component is specifically designed for Volvo FMX models (380, 420, 460, 500) equipped with D11K engines, as well as Volvo FM series trucks including the FM 500, FM 380, FM 420, and FM 460. It serves as a reliable replacement for original equipment to maintain system integrity.

Maintenance and installation guidance

When performing engine maintenance, it is recommended to inspect the pump for signs of leakage or bearing noise. For optimal service life, technicians should check the belt tension and inspect the pump housing during scheduled cooling system inspections.

Troubleshooting and performance

Proper selection ensures the cooling system maintains steady pressure throughout the engine block and radiator circuit.
