High and Low side a/c

leechris81 said

Your fittings are the same size due to being R12 and not 134. The low side is the one on the passenger side of the compressor and the high side fitting is the one on the a/c muffler on the left side of the compressor. Chances are, you will have to add 134 fittings before you can attach any of your loaner tools the system.

Thank you for that...if the guy would have told me I needed to put the converted fittings on I would have bought them while I was there...also the little rubber doughnuts that go in the fittings at the bottom to make an airtight seal are all broke so I need to see if o'reilly auto has spares. It's a conspiracy I swear.
