- 1). Lift the hood of the Chevy Tahoe and prop it open. Identify the low-pressure air conditioning recharge valve, which is typically behind and above the alternator.
- 2). Connect the valve attachment to the low-pressure valve.
- 3). Attach the pressure gauge to the hose if it is not part of the hose assembly. Attach the assembly to the can of refrigerant.
- 4). Tighten the attachments to the can of refrigerant until you hear a popping sound. This indicates that the can has been opened. You should then hear the refrigerant flowing into the Tahoe's air conditioning system. If the hose assembly has a trigger, hold down the trigger to ensure that the refrigerant is released.
- 5). Turn on the air conditioner and double-check the pressure. For most systems, the pressure while the air conditioner is running should be around 35 psi (pounds per square inch).
- 6). Turn off the engine and the air conditioner. Remove the hose assembly and close the hood.
