To add Freon to a 2006 Chevy Silverado, locate the low-pressure service port, which is typically found on the larger diameter A/C line, near the compressor. Remove the cap from the port and connect the A/C recharge kit to it. Make sure the engine is running and the A/C is set to the maximum cool setting while adding the Freon. Always check the vehicle’s specifications for the correct type and amount of refrigerant needed.

Add the Freon slowly, checking the pressure gauge on the can, until it reaches the recommended level, then disconnect and securely replace the service port cap.
