21296100 Volvo FM FMX Water Pump

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine and the radiator. By maintaining constant flow, it prevents overheating and ensures the engine operates within its designed thermal parameters under heavy-duty conditions.

This component is specifically engineered for compatibility with various Volvo models, including the FM series (FM 300 to FM 480) and the FMX series (FMX II, FMX III, and FMX 400/440/480 variants). It is an essential part for maintaining the thermal stability of these heavy commercial vehicle engines.

When performing cooling system maintenance, technicians should inspect the pump housing and impeller for signs of wear. It is recommended to check for coolant leakage from the weep hole or unusual bearing noise during routine service intervals to prevent unexpected engine overheating.

Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
