You should
not attempt to add Freon (refrigerant) to your Chevy Silverado's air conditioning system yourself. Adding refrigerant incorrectly can damage the system and is potentially hazardous. Refrigerant is under high pressure and can cause serious injury if handled improperly. It also requires specialized equipment to accurately measure and add the correct amount.
Instead, take your Silverado to a qualified automotive technician or AC specialist. They have the proper tools, training, and safety equipment to diagnose the problem and properly recharge the system. They can also identify if the leak is the cause of low refrigerant, which needs to be fixed before recharging.
