The water pump is a vital component of a vehicle's cooling system. It is responsible for circulating coolant throughout the engine and radiator, ensuring that the engine operates at an optimal temperature. By maintaining the proper temperature, the water pump helps prevent overheating, which can lead to severe engine damage. Typically driven by the engine's crankshaft, the water pump consists of a rotor and housing that work together to create a flow of coolant. Regular maintenance, such as checking for leaks and ensuring proper operation, is essential for the longevity of the water pump and overall engine performance.
