85003708 Volvo FH Compatible 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 vehicles operating under high engine loads or in hot ambient conditions, a high-flow, durable pump is essential to prevent overheating and protect engine longevity.

Compatible vehicles and engines

This component is specifically designed for Volvo FH models, including variants 400, 440, 480, 500, and 520, as well as Volvo FH16 units equipped with D16K engines. It provides reliable performance for these specific heavy-duty applications.

Maintenance and replacement

Technicians should inspect the pump during routine belt service. Symptoms of failure often include coolant leaking from the weep hole, unusual noise from the bearing, or visible play in the shaft. Replacing the pump alongside the timing or alternator belt is recommended to ensure system integrity.

Troubleshooting guidance

Consult your authorized distributor to confirm exact fitment for your specific engine configuration.
