How to install freon in a Nissan Frontier?

To install Freon in a Nissan Frontier, first ensure the vehicle is off and locate the low-pressure service port, usually found on the larger AC line. Attach the refrigerant can's hose to this port and start the vehicle, setting the AC to max cool. Open the can’s valve to allow the Freon to flow into the system, monitoring the pressure gauge to avoid overfilling. Once the desired pressure is reached, disconnect the hose and check for any leaks.
