Adding freon to 98 bravada

To add Freon to a 1998 Oldsmobile Bravada, first ensure you have the correct type of refrigerant, typically R-134a for that model. Locate the low-pressure service port, usually found on the larger diameter AC line. Attach the refrigerant canister with a gauge and follow the instructions to add the refrigerant until the system reaches the proper pressure. Always check for leaks and ensure the AC system is functioning properly after refilling.
