What type of AC refrigerant does a 1987 Chevy Blazer use?

1987 Chevy Blazers used R-12 (Freon-12) refrigerant. It's important to note that R-12 is no longer manufactured due to its ozone-depleting properties. If your Blazer's AC system needs refrigerant, it must be converted to a compatible alternative like R-134a, requiring specific components and procedures.
