Where do I add freon to a 2005 Jeep Liberty?

To add freon to a 2005 Jeep Liberty, locate the low-pressure service port, which is typically found on the larger diameter A/C line, near the condenser or compressor. Remove the cap from the service port and connect the refrigerant can's hose to it. Make sure the A/C system is running on the coldest setting before adding freon, and follow the manufacturer's instructions for the correct type and amount of refrigerant. Always exercise caution and consider wearing safety glasses during the process.
