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 cause severe engine damage. Typically driven by the engine's crankshaft via a belt, the water pump must maintain a consistent flow to effectively regulate temperature. Regular maintenance, such as checking for leaks and ensuring proper belt tension, is essential for the longevity of the water pump and the overall health of the vehicle.
