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, maintaining optimal operating temperatures. As the engine runs, the water pump draws coolant from the radiator and pushes it through the engine, absorbing heat in the process. This helps prevent overheating, which can cause severe engine damage. Typically driven by a belt connected to the engine, water pumps can wear out over time. Regular maintenance, including checking for leaks and ensuring proper coolant levels, is essential for the longevity and efficiency of the cooling system.
