21941086 Volvo FMX Water Pump

This water pump serves as a vital component within the engine cooling system, ensuring the consistent circulation of coolant between the engine and the radiator. By maintaining proper flow, it prevents overheating and protects heavy-duty engine components during intense operation.

Designed specifically for Volvo FMX models including the 380, 420, 460, and 500 variants, as well as various Volvo FM series engines such as the FM 380, FM 420, FM 460, and FM 500. This component is essential for maintaining optimal thermal equilibrium in these heavy commercial vehicle engines.

Technicians should inspect the pump during routine belt service or when signs of coolant leakage from the weep hole or bearing play are detected. Ensuring a precise fit and proper seal during installation is critical for maintaining system pressure and preventing long-term engine wear.

Check the compatibility list to ensure correct fitment for your specific vehicle model.
