What type of freon should I use for a 1998 Isuzu Rodeo?

If you will raise your hood and look at the stickers placed on the Plastic cover for the Radiator ( may be stuck to the underside of the hood) there are instruction and the type of Freon is listed there. Also you can go the the Auto parts store and they will sell you a little hose that will hook from the can to the lines to your air conditioner and instructions come with the kit. Cost about $10.00 for the kit here in Texas
