I have a 1992 K1500 I’m wanting to convert to R134a, the system hasn’t been run in I want to say 2-3 years. From the research I’m doing, my understanding is that to convert the system properly you need to change the fittings to R134a fittings, vacuum any existing refrigerant from the system, flush the system thoroughly and replace the accumulator, gaskets, seals and orifice tube, drain the oil from the compressor, ensure there’s no oil in it and then put the PAG oil in it (I think like 4oz?), turn it a few times and then once everything is hooked back up, pull vacuum on the system for like 20 minutes to make sure you don’t have any leaks. Since I know it’s been filled with r134a before, but I don’t know if it had r12 when it was filled, I’m gonna be replacing the compressor anyways. I’m also going to be replacing the rad for an unrelated reason, so when I do that I figure I’ll replace the condenser too. I’m looking at a UAC compressor kit on rockauto, it’s almost $300 but comes with the compressor, new gaskets and seals, new orifice tube, new accumulator and a new condenser as well as PAG oil. Has anybody used this kit before or what have y’all done to convert to r134a in these systems recently? Is it better to convert to a 95 condenser, and what will I need to do that? If I convert to the 95 condenser, will I need to use an orifice tube from a 95, or will I need to use one for my 92 model year?
I’ve got a bit of understanding on how the system works but not a ton, and advice is appreciated.
