R134a
10 w 40
I have a '92 and it is Freon 12. There are a couple of ways to tell. 1. There is a sticker under the hood that will tell the type of freon and the amount. 2. The best way is to look at the freon input connection. Freon 12 is a 1/4" flare fitting and freon 134A is much larger. A freon 12 system can be converted to 134a with a kit that is very available. They make these kits because freon 12 is unavailable and is now illegal to sell.
