Whoa all that's missing is the Powerpoint slideshow.

Thanks for the info!

My AC needs recharged or something. Ive been thinking of just cheaping out and dumping in R134A and if that doesnt work just gut the whole system.

I know that you can get kits around here that "supposedly" have the right stuff in it to keep the r-134 from eating up the seals on the older systems, dunno how effective they are, as I've never had A/C in any of my cars, just the trucks, and the F-150's all have r-134 as factory...
Besides, real men don't need no stinkin' a/C, LMAO :flame:

btw, this may make a good sticky thread...;)

Agreed. Nice job Jeremy, as once again you've impressed us all.

All vehicles after 1994 use R134a, So no F150 before 94 used R134a. The only exception to this would be Honda, a few snuck out in 93 with R134a.

Right on... My '93 Lightning is a R-12 system... As was the '93 Grand Marquis before I replaced the compressor, lines and acculimator and converted it to 134A. I have a '93 Aerostar as well that is a 12 system...

Not to argue, but my '92 truck has r134a...has a sticker attesting to that, even.

(Unless it was factory changed over, but it DOES have a coupla stickers stating that only R-134a is to be used..)

Does it have a ford part number on the sticker? When i worked at autozone we had a stack of stickers for R134a conversions that would come in the cases of R134a. They looked pretty nice and convincing.

now that you mention the part#, I'll check tommorow...
I'll let ya know what i find out..

I converted my DD TC over to 134a about 3 years ago when I did my first heater core replacement. I have a friend with all the equipment and license to do a/c work. We changed the drier out to a 134a compatable unit and replaced all disturbed o-rings with the proper 134a green o-rings. He flushed the system, changed to the correct oil and charged the system with correct amount of 134a (80 % of r-12 i think) It has cooled good ever since. The compressor started knocking last summer, but I assume that was because of 218,000 miles on it. We put the compressor off my 120,000 mile TC on it and it's back in business.

i hate this topic all together,,so many times people want to "just dump in" what ever they can and mix up things that most of the time wont even mix. Better yet,,fewer take in consideration the lubricants involved as well as the capacity differences of r12/r134/fr12 and how much of that PEG or PAG oil is needed.

While i was in Iraq, kind of got forced into screwing with this stuff and never claimed to know AC at all but ill tell you that i found out this is infact pure rocket science. Its like the whole operation of putting on a new compressor is like surgury.

Since most of the military compressors had a sight glass on the side to view the oil level, i did come up with an average applicable to the general mechanic. About 1/5th the height of the compressor will be holding oil but,,,, several cc's less if its hoses are existing because they will have a measureable amount of oil in or on the interior of them already.

we would literally have to pour pag oil into the compressor from a graduated half gallon container marked off in CC's until the compressor was full, this would give us the internal volume of the pump. We would then note how much it took in cc's then pour it back into the container. The compresser internal walls would steal a few cc's since you cant stand there and drip try the thing all day so we figured that math in as well.

Typically we took the internal volume of the compressor and divided the compressor volume by 5 on a compressor replacement only and by 4.5 on a whole new system to get the proper oil amount. Of course there are complications like 50 foot ac lines as well that you have to sharpen your number 2 pencil on and do the cc calculations on hose diameter and lenght , expansion presures and other .

again,, i hate this topic.,,,,,:yuck:

If you are serious about putting A/c in your ride the best way would to buy all new stuff and go from there. But if you are like me and don't have the cash atleast buy a new O-ring set and replace all the orings don't forget the schrader valve stems and the recevier dryer. Then take it some place and have them vac it down to check for leaks. Next it isn't all that hard to put in the refrigerent. If you don't feel comfortable have the shop do that too. I will add that if you are putting R134a in there that you put in the auto adjusting oriface tube. Also that should get replaced no matter what you do as they tend to get pluged up easily.
