The water pump is a vital component of a car's cooling system, responsible for circulating coolant throughout the engine and radiator. By maintaining the optimal temperature, it prevents the engine from overheating and ensures efficient performance. Typically driven by a belt connected to the engine, the water pump operates continuously while the engine runs. Over time, water pumps can wear out due to corrosion, leaks, or bearing failure, leading to potential engine damage. Regular maintenance, including checking coolant levels and inspecting the pump for signs of wear, is essential for keeping the cooling system functioning properly and prolonging the life of the engine.
