21814005 Volvo FH II Water Pump

What does a water pump do?

This water pump serves as a critical centrifugal component within the engine cooling system, responsible for continuously circulating coolant between the engine block, cylinder head, and radiator. By maintaining consistent flow, it prevents thermal stress and ensures the engine operates within its optimal temperature range during heavy-duty service.

Compatible Volvo FH models

This component is specifically designed to fit Volvo FH and FH II models, including various engine variants such as the 380, 400, 420, 440, 460, 480, 500, and 540. It is engineered to meet the rigorous demands of heavy commercial vehicle engines used in transport and construction applications.

Maintenance and inspection

For proper maintenance, technicians should inspect the pump during timing belt or alternator belt service intervals. Key indicators for replacement include coolant leaks from the weep hole or unusual bearing noise. Ensuring a secure fit during installation helps maintain system pressure and prevents long-term engine overheating.
