Putting R134 in my 88 XJ
Has anyone converted their older (1988 R12 system) to R134. I am
contemplating converting mine since its new compressor time for me. I have a
bad hose and a bad front compressor seal leak. I would be getting a new
compressor and replacing all the other parts too. (receiver/dryer etc.). Has
anyone done this to an older Jeep? Did it work? I need mine to be cold while
going 5mph in rough terrain and 100 degree temps. I am guessing a shop will
charge me about 800 US dollars for this job. Does that sound right?

Re: Putting R134 in my 88 XJ
Kevin, R134 just isn't as effective as R12 is in the really hot temps. My
wife's 2002 a/c in her JGC uses R134 and it doesn't put out air as cold as
my '97 TJ does that uses R12. In fact, it was barely able to keep up with
the Las Vegas temps we encountered a few weeks ago. Is there anyway they
can repair yours AND use R12? I know the laws are strict but I think R12 is
still available for repairs if you're a certified a/c mechanic.

Re: Putting R134 in my 88 XJ
I'm with Jerry on this one. If you want cooling at 5 mph and 100 degree
temperatures, you want R12. You should still be able to get the system
charged with R12, but it will cost more than R134a. It will be worth it
though.
Ever been to Mexico? I hear they will sell you all the R12 you want...

Re: Putting R134 in my 88 XJ
Kevin's Jeep is an '88. It was originally designed for R12 and shipped with
R12 in it. "What the system calls for" is R12. If he converts it to R134a,
I don't think he will be happy.
(I think new vehicles started shipping with R134a in 1993 or 1994, but don't
quote that.)

Re: Putting R134 in my 88 XJ
From what the AC shops have been telling me, If I need to get a new
compressor then I might as well replace all the other parts too and convert
to 134. But R12 is 50 bucks a pound or so and The system only holds 2 or 2.5
lbs. So it sounds to me like fixing my R12 system would only theoretically
cost about 100 bucks more that converting all the parts over to R134. I need
all the cooling I can get here in SD. Maybe I will stay with R12. by the
way, I decided to charge the thing with 75 bucks worth of R12 just to get it
going again. The leaks are still there. I hope to get another year out of
these parts before replacing them. I just dont have time now. My last charge
lasted 3 or 4 years with the same compressor seal leak. The low side hose
looks like it is going bad though. It has a few very tiny micro pinholes
that seep oil.

compressor then I might as well replace all the other parts too and convert
to 134. But R12 is 50 bucks a pound or so and The system only holds 2 or 2.5
lbs. So it sounds to me like fixing my R12 system would only theoretically
cost about 100 bucks more that converting all the parts over to R134. I need
all the cooling I can get here in SD. Maybe I will stay with R12. by the
way, I decided to charge the thing with 75 bucks worth of R12 just to get it
going again. The leaks are still there. I hope to get another year out of
these parts before replacing them. I just dont have time now. My last charge
lasted 3 or 4 years with the same compressor seal leak. The low side hose
looks like it is going bad though. It has a few very tiny micro pinholes
that seep oil.

Re: Putting R134 in my 88 XJ
My Suburban had already been converted to R134a, so this year when it came
time to fix all the leaks I used R134a again. I have no refrigerant or air
leaks, a like new blower, and a new compressor and metering orifice valve.
I am disappointed with the result. If you want to be disappointed too, then
you could convert to R134a! I may just convert the Suburban back to R12
some day.

I am disappointed with the result. If you want to be disappointed too, then

My '95 XJ has the R134 stuff... Cools well enough even on a hot day here in
Houston... Looking back, I probably shouldn't have bought the black one
though... Black cars are not all that smart down here... Grace's Mercedes
was converted to the R134 stuff and it seems to cool as quick as when it was
running on R12...

I've noticed that also... The relay for my electric fan has been sticking
and I need to periodically jiggle it after stopping the vehicle so that it
won't keep running after I'm through driving it... It will run to the point
where the battery is just barely able to turn over the engine the next time
I'm ready to start it... When I have to open the hood, it is hot enough that
I need leather gloves... Part of that is the engine temperature, part of
that is that the vehicle is painted black and this is Houston during the
summer...
