Any anyone tried this? Is it a real conversion or just an adapter alone?

That kit doesn't appear to be different than the kits you can buy at your local auto parts store. At the vary least you should replace the drier/accumulator and flush as much of the R12 oil out of the system. You should NOT flush the evaporator as you could clog the valve that is attached to the evaporator. The R134A molecule as I understand it is smaller than the R12, if you had a leak with R12 your going to have the same leak or possibly worse with R134A. Finally do a " search " on this site you will find hours of reading. Good luck.

I don't reccomend any conversion from R12 to 134. It is not as thermally efficient, has higher operating temps and pressures and as stated above will have a tendency to create leaks.

So he is going to fix the leak and instead of converting the system to r134 ( $400 ) i have decided to keep the R12 ( just found 21 cans of R12 for $286,approx $14/12 oz can )....sounds pretty reasonable to me,any suggestions.. |

This sounds like the best alternative to R-12 I have seen ...
http://www.heco.net/freezone.html If you replace all of your 911's OEM rubber A/C hose with modern barrier hose, then do a conversion ... the prospects for good performance without leaks is much better! Not inexpensive, though!

I converted my 86 to R134. It leaked 1 can worth of freon per year before the conversion and 1 can worth of R134 per year after the conversion. I used the kit from Wal-mart and drained as much of the old oil out as I could. I tried to replace the reciever dryer but got the wrong one so I just used the old one. The AC worked just as well after as it did before. I saw no downside to the conversion.

Hi Eagledriver,
I want to do it since you already did and have a good result. Before I can ba able to do it, I have several question and I hope you don't mind. How does the conversion you bought from Walmart look compare to the package in the link I found in JCWhitney I posted above? Do you remember which parts does it contain? How do you drain oil out? Do you mean open up the valve and let it spray out or do you have to bring it to the pro so that they can suck it out? Isn't spraying R-12 out in the air is bad? Thanks.
