Where do you refill the freon on a Chevrolet aveo?

To refill the freon on a Chevrolet Aveo, locate the low-pressure service port, which is typically found on the larger diameter aluminum line between the compressor and the evaporator. Remove the cap from the port, connect the refrigerant refill kit, and follow the instructions on the refrigerant can to add freon. Make sure the engine is running and the AC is set to the maximum cool setting during the process. Always wear safety gear and check for any leaks before and after refilling.
