What does a water pump do?

This water pump functions as a vital component within the engine cooling system, facilitating the continuous circulation of coolant between the engine and the radiator. By maintaining steady flow, it prevents overheating and ensures the engine operates within its optimal temperature range during intensive service intervals.
