The water pump is a crucial component of a car's cooling system. Its primary function is to circulate coolant through the engine and radiator, preventing the engine from overheating. The water pump is typically driven by the engine's crankshaft via a belt or chain. As the engine runs, the pump ensures that coolant flows efficiently, absorbing heat from the engine and releasing it through the radiator. Regular maintenance, including checking for leaks and ensuring proper operation, is essential for the longevity of the water pump. A malfunctioning water pump can lead to severe engine damage, making timely replacement vital.
