20538845 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. Maintaining a consistent temperature is essential to prevent overheating and ensure the longevity of heavy-duty commercial engines during long-haul operations.

Compatible Volvo vehicles and engines

The component is compatible with Volvo FH series trucks, including variants 400, 440, 480, 500, and 520, as well as Volvo FH16 models equipped with D16K engines. This ensures precise fitment for specific engine architectures used in heavy commercial vehicles.

Installation and maintenance

When performing maintenance, it is recommended to inspect the water pump alongside the timing belt or alternator belt service. Technicians should check for signs of failure such as coolant leaks from the weep hole, unusual bearing noise, or excessive play in the shaft to prevent serious engine damage.

Troubleshooting and selection

For reliable performance in high-temperature environments, selecting a high-flow pump is vital. Consult your authorized distributor to ensure exact compatibility with your specific engine configuration.
