What does a water pump do?

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