All vehicles after the mid 90's use 134a coolant. It can be purchased at most auto parts stores and is easy to install. Don't bother with any of the special dyes unless you have the tools to do serious work on the AC. Make certain that you do not over-fill the AC. Watch the pressure indicator as you fill the system and do not allow the system to go over-pressure.
