21960481 Volvo FH16 III Cooling System Water Pump

What does a water pump do?

This water pump serves as a vital component within the engine cooling system, ensuring the continuous circulation of coolant between the engine block and the radiator. By maintaining steady flow, it prevents overheating and ensures the thermal stability required for heavy-duty operations.

Compatible Volvo FH series vehicles

This component is specifically engineered for Volvo FH16 III models, including variants such as the 550, 650, and 750. It is also compatible with various Volvo FH series engines including the 400, 420, 440, 460, 480, 500, 520, and 540 models, as well as FH16 II configurations like the 540, 550, and 600 series.

Installation and maintenance

For professional technicians performing engine maintenance, it is recommended to inspect the pump and its drive belt during every service interval. Replacing the pump alongside the timing or alternator belt can prevent unplanned downtime caused by bearing play or seal failure. When installing, ensure all mounting surfaces are clean to maintain a proper seal.

Troubleshooting cooling issues

Proper cooling system maintenance is essential for extending the service life of heavy commercial vehicle engines. If you notice coolant leaks from the weep hole or unusual mechanical noise, immediate inspection is required to prevent engine damage.
