How do you add freon to your 1995 Toyota Previa?

To add Freon to your 1995 Toyota Previa, first ensure the vehicle is off and locate the low-pressure service port, typically found on the larger diameter aluminum line. Remove the service port cap and connect the refrigerant can’s hose to the port. Start the engine and turn the air conditioning to the maximum setting, then slowly release the refrigerant into the system, checking the pressure gauge on the can to avoid overcharging. Once the desired pressure is achieved, disconnect the hose and replace the service port cap.
