21814005 Volvo FH16 II Engine Coolant Pump

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine block and the radiator. By maintaining consistent fluid flow, it ensures that the engine operates at its ideal temperature, even under high-load conditions. The construction focuses on durability to prevent overheating and potential engine damage during long-haul operations.

This component is compatible with Volvo FH models including variants 400, 420, 440, 460, 480, 500, 520, and 540. It is also specifically fitted to Volvo FH16 II engines such as the FH 16/540, FH 16/550, and FH 16/600 models. This ensures precise fitment for a wide range of heavy commercial vehicle applications.

For optimal performance, technicians should inspect the pump during belt or timing belt service intervals. Common signs of wear include coolant leakage from the weep hole or unusual bearing noise. Ensuring proper installation and checking for impeller play can prevent sudden system failures in the field.
