The water pump is a crucial component of a car's cooling system, responsible for circulating coolant throughout the engine and radiator. By maintaining an optimal temperature, the water pump prevents overheating and ensures efficient engine performance. Typically driven by the engine's crankshaft via a belt, the water pump consists of a impeller and a housing. Over time, wear and tear can lead to leaks or failures, resulting in engine damage if not addressed promptly. Regular maintenance, including checking for leaks and ensuring proper belt tension, can extend the life of the water pump and keep the engine running smoothly.
