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, maintaining optimal operating temperatures. As the engine runs, the water pump draws coolant from the radiator and pushes it through the engine block, absorbing heat. This process helps prevent overheating, which can lead to severe engine damage. Typically driven by the engine's serpentine belt, water pumps can wear out over time, leading to leaks or reduced efficiency. Regular maintenance and timely replacement are essential to ensure the cooling system functions properly and the engine remains in good condition.
