85000486 Volvo FMX II Compatible Water Pump

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 constant fluid movement, it prevents engine overheating and ensures stable operating temperatures during heavy-duty service. Built with high-strength components, this pump is engineered to withstand the thermal and mechanical stresses typical of heavy commercial vehicle engines.

Vehicle and engine compatibility

This component is specifically designed to be compatible with Volvo FMX II models including 460, 330, 420, 500, 540, 370, 520, 430, 400, 440, 480, and 380 variants. It is also suitable for Volvo FM series trucks such as the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430. This ensures precise fitment for various Volvo truck configurations.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine cooling system maintenance. When replacing the unit, it is recommended to check the condition of the drive belts and gaskets to prevent future leaks or premature wear. Proper installation ensures the mechanical seal maintains a tight fit against the housing to prevent coolant loss.
