How do you put freon in a Subaru Outback?

To add Freon to a Subaru Outback, first ensure the vehicle is turned off and parked on a level surface. Locate the low-pressure service port, typically found on the larger diameter AC line. Attach the refrigerant can's nozzle to the port, then start the engine and turn on the AC to the maximum setting. Follow the instructions on the refrigerant can for proper filling, monitoring the pressure gauge to avoid overfilling.
