What does a water pump do?

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 flow, it prevents overheating and ensures the engine operates within its intended thermal range, protecting vital components from thermal stress.
