85003125 Volvo FH16 D16K Water Pump

What does a water pump do?

This water pump plays a critical role in the engine cooling system by circulating coolant between the engine and the radiator. For heavy commercial vehicle engines, a high-flow pump is essential to prevent overheating during long-haul operations and high-load tasks, ensuring overall engine longevity.

Compatible Volvo engines and models

This specific component is designed for Volvo FH models (including 400, 440, 480, 500, and 520 variants) and Volvo FH16 units equipped with the D16K engine. It serves as a robust replacement for original equipment components in these heavy-duty applications.

Installation and maintenance

During installation, technicians should inspect the timing belt and drive belts, as these are often renewed alongside the water pump. It is vital to ensure all mounting surfaces are clean to maintain a proper seal and prevent coolant leaks from the housing or weep hole.

Troubleshooting and selection

To ensure correct fitment, always verify the engine code and vehicle chassis details before selection. A worn bearing or damaged impeller can lead to rapid temperature spikes, so regular inspection of the cooling system is recommended.
