The water pump is a crucial component of a vehicle's cooling system. Its primary function is to circulate coolant through the engine and radiator, ensuring that the engine operates at an optimal temperature. When the engine runs, the water pump draws coolant from the radiator and pushes it into the engine, absorbing heat. This process prevents overheating and helps maintain engine efficiency. Typically driven by a belt connected to the engine, water pumps can wear out over time, leading to leaks or failures. Regular maintenance and timely replacement of the water pump are essential for the longevity and performance of the vehicle.
