Where you refill freon in a 1994 Toyota supra?

To refill the freon in a 1994 Toyota Supra, locate the low-pressure service port on the air conditioning system, which is typically found on the larger diameter aluminum line leading to the evaporator. Remove the cap from the port and connect a refrigerant gauge and hose to properly add freon. Ensure the vehicle is running with the AC set to the maximum cool setting while you refill. Always check the manufacturer's specifications for the correct type and amount of refrigerant.
