MULEPACKHUNTER Report post Posted June 23, 2014 OK on the hush hush anyone have any connections for some R12 ac charging on a 1990 Toy 4x4? My buddy finally ran out of juice and I just got my truck back from a full rebuild overhaul and my AC was low. My mechanic wont mess with it so was hoping someone might have a freind, I have lots of tradeables including cash. I would also consider knowledge on converting to 134, I know very little on how or cost? Thanks in advance. Share this post Link to post Share on other sites
camoremi Report post Posted June 23, 2014 I think the conversion to r134 is just fittings to to fill and empty your system. They sell the conversion kit at oreily and I think it's pretty cheap Share this post Link to post Share on other sites

azshtr Report post Posted June 23, 2014 Yep just fittings, drain and refill. My 91 4Runner has been changed over. Easy Peazy. Share this post Link to post Share on other sites
muledeerarea33? Report post Posted June 23, 2014 be careful with the half butt retrofit. 134A builds more head pressure than R12 does and could blow the system up. It's cheaper to have it checked for leaks, fixed, then charged with R12 than replace the entire system later if it grenades. 1 Share this post Link to post Share on other sites
Hyperwrx Report post Posted June 23, 2014 My trapping truck, 1991 Ford Ranger, was R12 and I looked into getting the parts to convert it over. Too much money to do it right. On a suggestion from a mechanic I just bought the new inlets and dumped 134A in it and we're going on 2 years trouble free. Share this post Link to post Share on other sites

Hyperwrx Report post Posted June 24, 2014 They have R12 substitutes you can buy. Its expensive though. $40 a can. Its' called Freeze 12 I think. Look on Amazon and Ebay. Share this post Link to post Share on other sites
azphil Report post Posted June 24, 2014 If you have leaks make sure they are fixed before you make the conversation.you can put an additive in for the system oil, but it's better if you can flush the whole system and drain the mineral oil from the compressor. Refill it with pag oil (a synthetic oil). Make the switch to r134, it is avaliable most any where. In Phoenix at Grand and 19th /McDowell there is a place called Aapak. Very helpful and they have everything you need. They can make up new hoses if needed- much cheaper than buying new if needed. Share this post Link to post Share on other sites
muledeerarea33? Report post Posted June 24, 2014 R12 isn't banned its just not made anymore. Some shops still have it. A few in Tucson do. Our shop ran out about a year ago. Share this post Link to post Share on other sites
Edge Report post Posted June 24, 2014 There's lots of R12 for sale on CL, or you could don a disguise and slip into the shadows of Backpage. 1 Share this post Link to post Share on other sites
MULEPACKHUNTER Report post Posted June 24, 2014 Thanks guys, I thought the R12 was deemed bad for ozone and such. Been a while since i needed any ac work. I will look on craigs and if not I guess its convert time. Share this post Link to post Share on other sites
Edge Report post Posted June 24, 2014 R12 and mule flatulence are of equal concern to tree huggers these days. 1 Share this post Link to post Share on other sites
MULEPACKHUNTER Report post Posted July 31, 2014 Update. Bought 55 dollar retro kit from Napa and screwed 2 fittings on then charged with 134 and drove around in a jacket. I was expecting a pain in the rear. Share this post Link to post Share on other sites
