The water pump is a crucial component in a vehicle's cooling system. Its primary function is to circulate coolant through the engine and radiator, maintaining an optimal operating temperature. When the engine runs, the water pump draws coolant from the radiator and pushes it through the engine, absorbing heat. This process helps prevent overheating, which can cause severe engine damage. Most modern vehicles use a belt-driven water pump, but some may feature electric pumps for improved efficiency. Regular maintenance, such as checking for leaks and ensuring proper coolant levels, is essential to keep the water pump functioning effectively and prolong the engine's lifespan.
