21814005 Volvo FH III Water 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 prevents engine overheating and ensures thermal stability during heavy-duty operation. Built with high-strength components, this pump is engineered to withstand the rigorous demands of long-haul transport.

This specific unit is compatible with Volvo FH III models including 420, 460, 480, 500, and 540 variants, as well as AERO and LNG configurations. It is also fitted to Volvo FH II series engines such as the 380, 420, 460, 480, and 500 models. For precise fitment, technicians should verify the specific engine code against the required specifications.

When performing maintenance, it is recommended to inspect the water pump alongside the timing belt or alternator belt service. Technicians should look for signs of failure such as coolant leaks from the weep hole or unusual bearing noise. Proper installation ensures the longevity of the entire cooling circuit.
