The water pump is a crucial component of a vehicle's cooling system. Its primary function is to circulate coolant throughout the engine, ensuring optimal operating temperatures. By drawing coolant from the radiator and pushing it through the engine block, the water pump helps prevent overheating, which can lead to severe engine damage. Typically driven by the engine's crankshaft via a belt or chain, the water pump operates continuously while the engine is running. Regular maintenance, such as checking for leaks and ensuring proper fluid levels, is essential to keep the water pump functioning effectively and to prolong the life of the engine.
