How do you put Freon in a 1999 Chevy Suburban?
Freon is a refrigerant used in older vehicles, but your 1999 Chevy Suburban does not use Freon. It most likely uses R134a refrigerant, which is a more environmentally-friendly alternative to Freon. If your vehicle needs refrigerant, it's best to consult a qualified mechanic or automotive technician who has the proper tools and knowledge to handle refrigerants safely.
