The water pump is a crucial component of a vehicle's cooling system. Its primary function is to circulate coolant throughout the engine and radiator, ensuring optimal operating temperatures. By drawing coolant from the radiator and pushing it into the engine, the water pump helps prevent overheating, which can lead to severe engine damage. Typically driven by the engine's crankshaft via a belt, the water pump operates continuously while the engine is running. Regular maintenance, including checking for leaks and ensuring proper function, is essential for the longevity of both the water pump and the engine. A failing water pump can lead to engine overheating and costly repairs.
