3801418 Water Pump for Volvo FM Trucks

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine and the radiator. By maintaining consistent fluid flow, it prevents engine overheating and ensures stable thermal management during heavy-duty operation.

Vehicle and engine compatibility

This component is specifically engineered to fit a wide range of Volvo FM series vehicles. It is compatible with various models such as the FM 480, FM 440, and FM 380, as well as the FM II and FM III series including LNG variants like the 460 LNG and 500 LNG. This ensures precise fitment for diverse fleet requirements.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine belt service or when signs of coolant leakage from the weep hole appear. Proper installation ensures the impeller and mechanical seals maintain high-strength performance under high-pressure conditions. Check the compatibility list.

Troubleshooting and selection

Maintaining a stable cooling cycle is vital for preventing engine damage in heavy commercial vehicles. Regular inspection of the pump housing and bearings helps avoid unexpected downtime in the field.
