How do you recharge your AC 1984 Oldsmobile delta 88?

To recharge the AC in a 1984 Oldsmobile Delta 88, first locate the low-pressure service port, which is typically on the larger diameter aluminum line. Connect a refrigerant canister with a gauge to the port, ensuring the system is off. Start the engine and turn on the AC to the maximum setting, then slowly add refrigerant until the gauge indicates the proper pressure, typically around 30-40 psi for R-12 or R-134a. Monitor the system and avoid overcharging, as this can damage the AC components.
