It is on the end of the evaporator ( the part that cools the air). I decided that it was too much trouble to drop it down so I didn't change the expansion valve. The high pressure port is behind the vertical trim panel on the left side. (late model non-Westy) I don't know if the Westys have things arranged differently. Don't assume that the adapters from a "kit" will be correct. There are two different thread sizes for the original R-12 fittings: nominally 1/4 " and 3/16 ". Of course the quick connect 134A part is different for the high and low sides. Various permutations are possible. You may have to study them and shop around. Also, in my 91 GL there was very little clearance between the original R-12 high side fitting and the trim panel. I had to use the cheap, short, aluminum type of adapter that has no valve core of its own. Larry A. |
