I too have a uv light you can borrow don't know were frontrange is located but i'm in littelton ( if it makes life eaiser ) Can a r134 sniffer detect r12 ?? If so my shop has a sniffer and you wouldn't have to Wait For the dye to show, but we cannot work on r12 systems. (no licens, no equipment) I'm personally not a fan of dye because I've herd stories about the dye causing damage to the compressor because it's not oil. Or somthing goofy like that. I've never experanced it so it's all (myth) buy I know it's not in there from the assembly line so it problly shouldn't be In there. But it does make working on the system a Hell of a lot eaiser. Lol

I don't think so, but since I don't work on 134 systems I'm just guessing the chemistry is too different. I should have a sniffer, but the leaks I run across show up very quickly with dye and dye works everywhere - power steering fluid, ATF, coolant you name it. The dyes are different, but the kit with the goggles and light is just one kit with a bunch of dyes.

Mostly due to timing and convenience I am going to drop it off to Greg tomorrow. Frontrange and I had a good PM exchange and his offer of assistance was really great. Tim, you too. I bet the three of us could have had a good wrenching session.

I just don't have the time right now before CM. I'll report back tomorrow afternoon

Its done, R-12 out, R-134 in + dye, and blowing cold, but on a day like today its all cold. There was no obvious leak found. System held vacuum for 1/2 hour, which is of course less pressure than inside the operating A/C system. We'll test it soon in moab.

Did they find a leak and fix it?

You may find that your A/C isn't as icy frigid with the R-134. Still better than none at all, though.

So, where'd you take it? I'd like to get the AC working again in our 4Runner, if for no other reason than to assist in defogging the plastic Canback and half door windows.

No leak detected. Greg said that he commonly has people come in with the AC having failed after a winter of inactivity but holding a fine charge after that.

Shop is the Toy Shop. Greg Kochiss, owner. 1185 S. Cherokee St., Denver, CO 80223. (303) 744-7621. I have been a customer for 12 years. Naturally, I also frequently go to our club member and supporter Slee Offroad.

Sad to say it sounds like your mechanic is just winging it. A slow leak with R12 will surely become a much faster leak with R134.
