Where to put freon in a 1992 Acura Vigor?

To add Freon to a 1992 Acura Vigor, locate the low-pressure service port on the AC system, which is typically found on the larger diameter aluminum line between the compressor and the evaporator. Remove the cap from the port, attach the refrigerant can hose, and follow the instructions on the can for adding Freon. Ensure the engine is running and the AC is set to the max cool setting during the process. Always wear safety gear and consider consulting a professional if you're unsure.
