A/C recharge
 

Anyone recharge their a/c on a TJ? How did it go? Any probs?

Re: A/C recharge
 

If it is pretty low - it has a leak......biggest problem is finding the
leak. look for oil around all of the joints or maybe even coming from a
pinhole on one of the lines. Used to be able to recharge using the gauges
(ambient temp + certain amt was one of many formulae going around) - but
now, I hear that it is best to pump it out - hold a vacuum for a couple of
hours (maybe even overnight to be sure that there are no leaks) then replace
freon by weight.
I do a/c so infrequently that I have to sit down with a book & relearn it
every time.

Weight replacement is recommended for R134a. I presume that older systems
with R12 are OK to recharge by gauges, but the weight method will still be
more accurate. There should be a sticker under the hood which states the
total refrigerant capacity. AC Source has an R12 Recover/Recycle system
that can be converted to R134a and (they say) is within the price range of
the DIY mechanic. http://www.acsource.com/product.asp?3=204 I am tempted
to buy it, because I have two air conditioned vehicles and it is a 150 mile
round trip to get an AC technician to look at one. I finally found a good
one in my area after about four years living here. Unfortunately, everyone
else in four counties knows about him already. A poor AC technician can
burn up your money in labor, parts, and refrigerant pretty fast...

Ditto on the leaks. A good place to start is to get an O-ring assortment
that is compatible with your system and replace all the O-rings at once.
This of course assumes that you have some way to remove the refrigerant from
the system and evacuate it before refilling.

I don't know how hot it gets in your area of Colorado, but here in
Vista, California the summers have been getting colder and colder. My
Bronco and it's R-12 gave up year before last and I haven't needed it,
the 2/70 A/C works just find.

Grand Junction is sorta unique, being an honorary part of Utah.
And housing subdivisions built on uranium tailings that don't
need streetlights, just let the backyard glow.

And really not as much fun place to gas up since Gay Johnson
closed their restaurant.
