A/C recharge

[riki5156]

I've got a 90 LE cummins that I just got done cleaning out the heater box and man was I surprised at how clogged the heat and a/c cores were. I haven't had heat in about 20 years. Flushed both cores,cleaned the needles and leaves out of the box and fixed a freon leak. Thank you you tube. A lot of work to get the heater box out. I'd rather rebuild a 727 in the driveway pouring rain than do that again. Now the heat works wonderfully and the a/c will need recharging. Back in the late 90s I was attending Goodguys Pleasanton and came across a swap booth selling r12 replacement I think called quik-cool which I tried and it worked great.Probably 95% as cold as R12. Now I have to recharge the air and I see all sorts of r12 replacements on amazon-ebay. I don't want to convert to134 already done that on a motorhome, no thanks. Anyone have any thoughts on R12 replacements?

I think the R-134 change overs work when you look into the expansion valve change also. The R-134 has different rate of expansion then the R-12. If you can find all components that work with the R-134, you'll have a much better experience then before! The compressor shouldn't change as it just does it's one job, it's all the other parts that affect the cooling. Hope this helps with the project. R-134 much easier to find and will do the job fine.
