The water pump is a crucial component of a vehicle's cooling system. Its primary function is to circulate coolant throughout the engine, helping to maintain an optimal operating temperature. By drawing coolant from the radiator and pushing it through the engine, the water pump prevents overheating and ensures efficient performance. Most water pumps are driven by the engine's serpentine belt, and they typically feature a durable design to withstand high temperatures and pressure. Regular maintenance, including checking for leaks and ensuring proper operation, is essential for the longevity of the water pump and the overall health of the engine.
