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, preventing overheating and ensuring optimal performance. Typically driven by the engine’s crankshaft, the water pump helps maintain a consistent temperature by facilitating heat exchange. When the engine runs, the pump draws coolant from the radiator and pushes it through the engine block, absorbing heat. A malfunctioning water pump can lead to serious engine problems, including overheating and damage. Regular maintenance, including checking for leaks and ensuring proper function, is essential for vehicle longevity.
