How do you recharge the AC on a 2004 Subaru Outback?

To recharge the AC on a 2004 Subaru Outback, start by locating the low-pressure service port, usually found near the accumulator, and attach a refrigerant can with a gauge. Make sure the AC is set to the maximum setting and the engine is running. Open the can and allow the refrigerant to flow into the system, monitoring the pressure gauge to ensure it reaches the recommended level. After charging, check for any leaks and ensure the AC is blowing cold air before disconnecting the gauge.
