Where do you add freon to a 2000 Lincoln continental?

To add freon to a 2000 Lincoln Continental, locate the low-pressure service port on the AC system, which is typically found on the larger diameter aluminum tubing near the compressor. Remove the cap from the service port and attach the refrigerant canister's hose to the port. Ensure the vehicle is running with the AC set to maximum cool while adding the freon slowly until the desired pressure is reached. Always check the manufacturer’s specifications for the correct refrigerant type and amount.
