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, ensuring that the engine operates at an optimal temperature. By maintaining this temperature, the water pump helps prevent overheating, which can lead to serious engine damage. Typically driven by the engine’s crankshaft, the water pump draws coolant from the radiator and pushes it through the engine, where it absorbs heat. Regular maintenance, including checking for leaks and ensuring proper function, is essential for the longevity of both the water pump and the engine.
