I am trying to write a guide for AC for the W123, but am unknoeledgeable, but willing. :D Where there is a will, there is a way.
So, who wants to help. There is an AC inlet on the top and bottom, right? What are each of these used for, I know one is high pressure low pressure, etc. Which one do you put coolant (R12) dye, and oil in? I will be using what you say to write my guide, so be detailed, and I'll publish it, and helpfully help some guys out.
