To add Freon to a 2004 Chevy Classic, first ensure the engine is off and the A/C system is off. Locate the low-pressure service port, typically found on the larger A/C line, and connect a refrigerant gauge or canister with a hose. Start the engine and turn the A/C to the maximum setting, then slowly open the refrigerant canister to allow Freon to flow into the system while monitoring the pressure gauge. Once the recommended pressure is reached, disconnect the canister and replace the service port cap.
