21814036 Volvo FH II Water Pump

The water pump serves as a critical component within the engine cooling system, functioning as a centrifugal-type pump that continuously circulates coolant between the engine block, cylinder head, and radiator. This constant circulation is essential to maintain optimal operating temperatures and prevent engine overheating during heavy-duty service.

This specific water pump is compatible with Volvo FH and FH II models, including variants such as 380, 420, 460, 500, and 540. It is engineered to meet the strict requirements of Volvo OE specifications, ensuring a precise fit for these heavy commercial vehicle engines.

To maintain system integrity, it is recommended that technicians inspect the pump during routine belt services. Common indicators for replacement include coolant leaks from the weep hole or unusual bearing noise. Ensuring proper installation helps maintain stable thermal management for the engine.

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