Procedure

1. Park the Chevrolet in a safe area. Turn off the engine. 
2. Pull the hood release under the dashboard until you hear your Chevrolet hood pop open.
3. To add freon to your Chevrolet, you need to locate the A/C low-pressure charging port in the engine bay.  The A/C charging kit connector will not fit on the port for the high-pressure line.
4. Carefully remove the cap from the low-pressure port by twisting it counterclockwise. Connect your A/C hose to the A/C charging port. You are almost ready to add freon to your vehicle A/C system. Don’t start adding refrigerant to your Chevrolet A/C system yet.
5. Start the engine, turn A/C on, and set it to the max cold setting. Set the blowing fan to maximum speed. Now you are ready to recharge the Chevrolet A/C system. Add refrigerant as directed by the A/C recharge kit you are using.
6. Press and hold the trigger until your Chevrolet A/C is charged. This process can take several minutes. When the A/C system is low on freon, the compressor may not be engaged at first.

Notes

• As you add refrigerant, you should see the compressor kick in. As you charge, the system stops charging every minute to obtain a pressure reading.
• Continue adding refrigerant until your gauge reaches the charged range. Do not allow the system to overcharge.
• This procedure is used to top off the Chevy A/C system. If your A/C system is empty, you must remove the air from the system first.
• The A/C charging port location can vary between Chevrolet models, but it will be located in the engine bay in all cases.
• Before recharging the Chevrolet A/C system, ensure that other components are in working condition.

Chevrolet A/C may stop working if it is low on freon and other problems such as A/C compressor not working, bad A/C clutch, bad temperature sensor, major freon leak, etc.
