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 that the engine operates at an optimal temperature. By maintaining a consistent flow of coolant, the water pump helps prevent overheating, which can lead to severe engine damage. Typically driven by the engine's crankshaft, water pumps can be mechanical or electric. Regular maintenance, including checking for leaks and ensuring proper operation, is essential for the longevity of the pump and the overall health of the engine. A malfunctioning water pump can result in decreased performance and increased repair costs.
