21941086 Volvo FM D13K 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 consistent fluid flow, it prevents overheating and ensures the engine operates within its designed thermal range under heavy-duty conditions.

The unit is specifically engineered for Volvo FM trucks, including models such as the FM 380, FM 420, FM 460, and FM 500 featuring the D13K engine. It is also compatible with other heavy commercial vehicle engines where the specific dimensions and mounting points match the Volvo OEM requirements.

For professional technicians, it is recommended to inspect the pump and its seals during routine belt service. Monitoring for signs like coolant leaks or unusual noise can help prevent system failures. Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
