21814040 Volvo FM Water Pump

This water pump serves as a critical component within the engine cooling system, facilitating the continuous circulation of coolant between the engine and the radiator. By maintaining stable thermal management, it prevents engine overheating during heavy-duty operations in trucks and construction machinery.

This specific unit is designed for Volvo FM series applications, including models such as the FM 460, FM 500, FM 420, and FM 380. It is also compatible with various Volvo FM II and FM III configurations. This ensures precise fitment for a wide range of heavy commercial vehicle engine variants.

For optimal performance, technicians should inspect the pump alongside belt service intervals. When replacing the unit, ensure the cooling system is properly bled and check for any signs of leakage or bearing play in the old assembly to maintain long-term system integrity.

Consult your authorized distributor to confirm exact fitment for your specific chassis.
