Re: [MBZ] 87 td AC woes

No problem. I've checked out Envirosafe before but didn't realize it was compatible with freon, and that was good to know. Started to order and use Envirosafe about the same time (Jim?) described his use of propane/butane. Couldn't find any butane in the stores (Walmart has a butane/propane mix

Re: [MBZ] 87 td AC woes

If it is leaking, that is the first priority. I cannot see throwing good hydro/fluorocarbons after bad. Either the system is 100% functional or I boot it off the car. 85td AC has always been prettly reliable. Still blowing fairly cold this AM, but ambient was 58. Compressor engages fine. Not sure

I think that is what happened to Freeze 12. Got caught up in the regulatory anus of the ass. Great solution to the problem the goobers created to benefit Dupont, so the goobers had to regulate it into oblivion. Jim Cathey via Mercedes wrote: The Law, in this case, is an overreactive ass.

Re: [MBZ] 87 td AC woes

Butane and propane are fully miscible with Freon, and mineral oil. It's fine to top off an R12 system with HC. Decision matrix: A: If it's not leaking, I don't need to top it off. No problem. B: It it were leaking and if I were not to fix it, the rest of the R12 would leak out in time. No

Re: [MBZ] 87 td AC woes

It's Envirosafe. It is marketed as a 134a replacement, because to be technically within the law, an R-12 system has to be converted to R-134a, and then converted to ES or other alternative refrigerants.  ‎https://www.es-refrigerants.com/?site=dom

Understood. However, I was not aware that it was intended to be used as a “top off” for an R12 system. I interpret that statement as saying that any remnants of R12 or R134a won’t react or affect the alternative refrigerant. Here's the thing...when you mix two (or more) refrigerants you

Re: [MBZ] 87 td AC woes

Me neither. I just thought the propane/butane stuff was a replacement, not something that was directly compatible with R12 in an existing system. That uis, it plays nice with compressor oils and other parts of an R12 system, but not the refrigerant itself. -D > On May 25, 2017, at 5:00 PM,

That's when you get some of the evercool12 industrial and put that in. Works like a charm and mixes with the R-12 just fine. You just have to have the right gauge set to or hose to attach the can to your gauge set and away you go. One small 12 oz can replaces a full can of R-12 which IIR is 1

If the AC won't run, push the stem down in the low pressure port to see if the system still has freon in it. If freon squirts out fairly strongly, buy a can of freon at FLAPS OR Wallmart which has a little gauge and and a short hose on top. Start the car and let it idle, turn the AC fan on full

Good call! I guess I assumed that he had had it vacuumed and filled. At HF yesterday I noticed their vacuum pumps were about $100 and $160, and their gauge sets were about $60. IMO he should fix the auxiliary AC fan sometime during the repair and put a shroud on the main fan if he can find one

Ok so it has bubbles in the window. Ambient was 68 and it put out very cold air on the way to work. Compressor may not be shot? No accessory fan at all, though would not expect it with this weather. Might as well order the gauges. On May 24, 2017 10:11 AM, "Meade Dillon via Mercedes"

Only one thing that Gerry left out. Did you connect a vacuum pump after you put the NEW receiver drier in and a new expansion valve. Each time the compressor quits all the cleaning has to be done and a solid vacuum pulled. Living in Florida I run the pump for at least an hour just because I

Randy, There is a fuse that should blow if the compressor stays on too long. That is what would happen with my '87 wagon when the KLIMA relay died and I needed AC for a long highway trip, so I rigged continuous power to the compressor. I think the fuse would only hold for about ten minutes. I
