I have gauges coming in the mail. I will check the pressure. I only assume it has R12 in it because all the ports are original R12 and the PO never mentioned having it switched. Plus there are no conversion stickers under the hood. So I could likely just add R12... my concern is how cold it will get. I know I am at a disadvantage with the wagon being a larger area to cool. I like the AC to be too cold on hot days.
