Well, to do it right, you first need to track down why the freon leaked out. It's typically just a dried up o ring or a loose fitting. Also, on old cars, I like to replace all of the O rings since they are very cheap anyway. Do that, screw on the adapters, put a vacuum pump on it to pull the moisture out of the system, then recharge.

A/C R134 conversion recharge
I was surprised how easy it was, and how cold it still gets w/ the 134a. 4 yrs ago I converted my 90 accord over, and it still blows a cloud of condensation out the vents in the hot summer, about 37degrees.RSXSLVR79;58251 wrote:Well well,
Is a R12 to R134 conversion easy? Can anybody in the club do one? I am purchasing a car that the AC is dead in.
Good luck. &as said, replace as many o-rings as possible, reassemble w/ new fittings, and pull a vacuum for 20-30 mins, then refill w. oil & refrigerant to proper amount. be sure to put the label under the hood w/ proper capacities of oil & 134a (in ounces), and record the date of the conversion.
If you want to go even farther, you could take out the compressor and invert it to try to dump any old oil out.
darn i need to start looking at dates.... this post originated nearly 2 mos ago. summer's over (a/c weather, anyway). Hopefully the info is useful to someone though. cheers!
