Anyone used one of those conversion kits at the auto parts stores? I want to try one on my 92 Ranger. Someone at work said he used one and did not have to change anything other than the freon.

Re: AC Conversions
my current system isn't working. I had it looked at but it would have cost too much for them to run all their tests befor filling it. I am thinking about doing it though. summer is coming!!!1968, 69 351W,NP 435, Stak 5.22, D44 with 4.10's, chebby discs and a detroit, 9" with 4.11's and a lockright. 35" MTR's, TRO, WH cage, ps, pb, 3.5" susp, 2" body lifts, pile of parts in the garage, empty wallet!

Re: AC Conversions
R12 is stupid expensive, and R134A works just as good. Anyone who tells you otherwise doesn't know how to do A/C work very well. As for the conversion, you need to install the quick disconnects on the old compression style fittings and flush the system. R12 uses mineral oil, R-134a uses ester oil. I can do all the work in my garage, very simple.... It's honestly not rocket science. But the system does need to be able to pull a vacuum, so if there are leaks then they will have to be fixed. Air has moisture in it, any moisture present will decrease the efficiency of your system.SOLD: 1975 Ford Bronco: 105" wheelbase, King 14" c/o shocks, King 2" air bumps w/ Duff arms, 4 link rear w/ coils.

Re: AC Conversions
I had it charged when I got it running. It worked for 2 years. The third year it would work for awhile, then stop working. Seemed to work fine until it heated up on the way home. I don't think there is any serious leaks though. Can you evacuate my system or should I take it to a shop for that?1968, 69 351W,NP 435, Stak 5.22, D44 with 4.10's, chebby discs and a detroit, 9" with 4.11's and a lockright. 35" MTR's, TRO, WH cage, ps, pb, 3.5" susp, 2" body lifts, pile of parts in the garage, empty wallet!

Re: AC Conversions
If it's only working sometimes then it probably leaked down to where the low pressure switch can't decide if it wants to stay closed or open. I can't evacuate it, but if it is already empty, I can do the work and re-charge it... After i make sure there aren't any leaks of course. Many times a slow leak is a bad A/C compressor.SOLD: 1975 Ford Bronco: 105" wheelbase, King 14" c/o shocks, King 2" air bumps w/ Duff arms, 4 link rear w/ coils.

Re: AC Conversions
well I watched the video and it seems to easy. evacuate the system, install adapters on the valves and fill it. I think I am going to try it soon.1968, 69 351W,NP 435, Stak 5.22, D44 with 4.10's, chebby discs and a detroit, 9" with 4.11's and a lockright. 35" MTR's, TRO, WH cage, ps, pb, 3.5" susp, 2" body lifts, pile of parts in the garage, empty wallet!

Re: AC Conversions
when gm had us retrofit from 12to 134 they said we had to go to teflon hoses.flush and refill with pag 150 oil and replace the orofice tube,dryer and low press cycle switch as well as put in a bigger condensor. later bulletins were excluded the hose and condensor replacement. my 90 has had 134 in it with just pag and the 134 orofice since 1992 when the compressor took a dump and cools just as good as the 12 when it's working right.6 jeeps 2a-cj5. bronco now. 70,efi 302,c4,ps,pb, 4.56's detroit's 2bl,4.5 rollin on 37's

Re: AC Conversions
For some reason when R134a conversions first came out you HAD to replace the Receiver/dryer, hoses, fittings, oil, flush the system, and swap to the green o-rings. Now, I don't know what had changed, but all you need to do is loctite on some new conversion fittings on your old R12 fittings, suck a vacuum on the system, do the math on how much R134a you need (R134a requires like 25% less) and you're done.
I have everything you may need, but really Harbor Freight sells a decent vacuum pump for cheap, that's about the only thing you really need. I would suggest buying an A/C O-ring kit from Napa and replace your O-rings just because it's cheap and easy. The lines either thread off or have quick connect fittings like the EFI fuel lines.Mark Harris

Re: AC Conversions
Anytime you crack open an A/C system you should replace the dryer. And the secret to getting the conversion to work good is using 20% less R-134a than what the sticker calls for R-12. I have a digital scale that makes it easy to get the right amount.SOLD: 1975 Ford Bronco: 105" wheelbase, King 14" c/o shocks, King 2" air bumps w/ Duff arms, 4 link rear w/ coils.
