A 1995 Mitsubishi Galant 2.4L most likely used
R-134a refrigerant. While some older vehicles used R-12, the transition to R-134a was well underway by 1995. It's highly improbable a 1995 model would still use R-12.
However, always check your vehicle's AC system sticker (often located under the hood) for definitive confirmation. This sticker will specify the correct refrigerant type.
