Where do you put freon in a chevy Corsica?

To add Freon to a Chevy Corsica, locate the low-pressure service port on the A/C system, which is typically found on the larger diameter aluminum line. Remove the cap from the port and connect the refrigerant recharge kit following the manufacturer's instructions. Start the engine and turn on the A/C to the maximum setting while adding the Freon until the system reaches the recommended pressure. Always ensure you are using the correct type of refrigerant specified for your vehicle.
