YOU don't! If your system is R12 (freon)it should ONLY be serviced by a professional. The way to determine is if you have quick-couple service fittings, it is 134A (not freon) equipped, if it has threaded service fittings, it is R12 (freon) equipped. When you take the vehicle to a professional, he will convert your R12 system (if it is so equipped) to 134A. R12 (freon) has not been manufactured since 1995 by law (Montreal Accord) and it is VERY hard to find. A license is required to purchase R12 and it may not be legal to sell in your state.

Actually Freon is a registered trade name or trademark for E. I. DuPont. It is not strictly R-12. R-134a is commonly called Freon.
