85000486 Volvo FMX D11K 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 block and the radiator. By maintaining consistent flow, it prevents overheating and ensures the engine operates within safe thermal limits during heavy-duty service cycles.

Compatible Volvo vehicles and engines

This part is specifically designed for Volvo FMX models equipped with the D11K engine, as well as various Volvo FM series trucks including the FM 480, FM 440, FM 380, FM 340, FM 300, FM 400, FM 360, FM 390, and FM 430. It provides a reliable replacement for heavy commercial vehicle engines requiring precise coolant management.

Installation and maintenance

For workshop technicians performing maintenance, it is recommended to inspect the mounting surfaces and seals during installation. To ensure a proper fitment, verify that the cooling system components are free from debris and that the drive belt tension is correctly adjusted according to manufacturer specifications.

Troubleshooting and inspection

Regular inspection of the pump housing and weep hole can help identify early signs of wear or seal failure before they lead to system-wide overheating issues.
