I just converted my 84 244 to r134. Replaced shot compressor(used poe oil) flushed system replaced all o-rings, drier, and expansion valve, pulled vacuum until free of moisture, then charged w/ 36oz's of r134. This is what I'm curious about. My manifold guages read between 130 and 145 highside and between 10 and 25 lowside. I have'nt coated my expansion valve yet was wondering what to use and was also wondering if the wire w/ the coil on the end needed to be in a special place, I just stuck it in the opening the other came from. I covered it w/ my hand and the psi seemed to go up and the air got a little colder. any input is appreciated.
