In my 92 coupe i came across a couple cans of the old freeon (the good stuff). But i think there could be a leak somewhere in my system. So is the dye out in the stores to put in the system or does a shop have to do it? Also on the label of the can it say's to hold upright to get the oil and upside down to get the freeon, so how do i know what i need or the most of? peace
