What does a water pump do?

The 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 a constant flow, this belt-driven component prevents thermal buildup, ensuring the engine operates within safe temperature parameters even under high load conditions.
