Checking the Pressure:

Before you start, make sure the truck’s engine is running and the AC is turned on. Connect the blue hose to the low pressure port and the red hose to the high pressure port. Hold the gauges upright and observe the pressure readings.

Connecting the Gauges:

Connect the yellow charging hose to the refrigerant canister. Attach the other end to the center hose connection of the AC gauges. Open the valve of the refrigerant canister slowly and allow the pressure to equalize.

Reading the Gauges:

Take note of the readings on the low pressure and high-pressure gauges. The ideal pressure range should be specified in the truck’s manual. If the readings are too low or too high, it may indicate a problem with the AC system.

Adding Refrigerant:

If the pressure is below the recommended range, you may need to add refrigerant. Attach the canister to the center hose connection and open the valve. Slowly fill the system until the pressure is within the desired range.

Disconnecting the Gauges:

Carefully close the valves on the gauges, and then unscrew the hoses from the ports. Remember to securely fasten the caps on the ports to prevent any leaks.
