What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for continuously circulating coolant between the engine block, cylinder head, and radiator. By maintaining steady flow, it prevents thermal stress and ensures the engine operates within its ideal temperature range during heavy-duty service.
