The water pump is a crucial component of a car's cooling system. Its primary function is to circulate coolant throughout the engine and radiator, preventing overheating. The pump is typically driven by a belt connected to the engine, ensuring that it operates continuously while the engine runs. Over time, water pumps can wear out due to corrosion, leaks, or bearing failure, which can lead to engine overheating and potential damage. Regular maintenance, including checking for leaks and ensuring proper coolant levels, is essential to prolong the life of the water pump and ensure optimal engine performance.
