hello everyone, just read up on a forum of a guy using propane as refrigerant on these trucks and he got crazy temps. problem is he hasn’t been active in 13 years and he mentioned something about installing an evap temp switch and putting a restriction in the suction line as well as using the “smallest orfice tube” he could find. anyone got some info on that? also please don’t come and tell me the “dangers” of what i’m doing. i’m well aware. what kind of restriction and how big? where did he tap the wires for the evap switch into? what size orfice do you think he went with?
i’m also well aware none of you are tapped into @89ford73 ’s life but you can find his write up under his page “what is the coldest ac temp achievable?” just seeing if any of you guys tried the propane method and what you did.
