The water pump is a crucial component of a vehicle's cooling system. Its primary function is to circulate coolant through the engine and radiator, ensuring optimal operating temperatures. When the engine runs, the water pump draws coolant from the radiator and pushes it into the engine block, where it absorbs heat. This heated coolant then flows back to the radiator, where it is cooled by air flow. A malfunctioning water pump can lead to overheating, engine damage, and reduced performance. Regular maintenance, including checking for leaks and ensuring proper operation, is essential for the longevity of both the water pump and the engine.
