85000957 Compatible Water Pump — Volvo FH16 II

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, ensuring continuous coolant circulation between the engine block and the radiator. By maintaining steady flow, it prevents overheating during high-load operations common in heavy commercial vehicles.

Compatible Volvo engines

This specific model is designed for use in Volvo FH series engines, including variants such as the 460, 500, 540, 420, 520, 440, 480, and 400. It is also compatible with Volvo FH16 II models, specifically the FH 16/600, FH 16/540, and FH 16/550 configurations.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine belt service. Checking for coolant leaks from the weep hole or unusual bearing noise can prevent sudden engine overheating. When replacing this component, ensure all mounting surfaces are clean and use high-strength components to withstand vibration and temperature fluctuations.

Troubleshooting and service

Maintaining a robust cooling system is essential for engine longevity in long-haul applications.
