A: Make sure the valves are set to the open position by turning the valve counterclockwise. Attach the pressure valves to the appropriate AC line connector. Once all lines are attached make sure the lines are free from any moving parts from the engine compartment. Open both valves in the gauge manifold. Start the vehicle and start its air conditioning system. Monitor the results on the gauges and reference the results to the owner's manual as necessary. If required, charge your vehicle with the appropriate refrigerant. To do this, Make sure you have the correct refrigerant for this may damage your vehicle if incorrect. Connect the yellow line from the manifold to the refrigerant and open the valve on the tank. Be sure to bleed the yellow line using the bleeder valve. This removes any and all air that could potentially find its way into your AC system. Start your vehicle and turn on your AC system. Open the valves and allow the system to fill, monitoring the gauges until they reach the appropriate pressure. Q: Are the gauges liquid filled? A: The gauges are not liquid-filled.
