What does a water pump do?

This water pump plays a critical role in the engine cooling system by circulating coolant between the engine block and the radiator. By maintaining consistent flow, it prevents overheating and ensures the engine operates within its optimal temperature range, which is vital for long-term component durability in heavy-duty applications.
