Thanks, Craig. That like will prove quite useful when I explain to friends
struggling with AC woes how it works.
Today, post gym, pre 100 degrees, I’m going to try to find my leak or leaks
with the sniffer I just got from the large wimmen, or as my 87 year old pop
called it, Amazizzle. He

True, I was speaking more to O rings used on hose fittings. The top and back
plates of compressors where the fittings are located can have weird
seals/O-rings. Those typically come with the part, too.

For the most part, yes. There can be weirdly-shaped ones, but they’re not
common. You can buy specific O-rings or an assortment that’s not expensive.

O-ring question. Are AC o-rings universal by color or do I need to get
specific ones for the truck?

It's not _bad_ advice, but it is more trouble and cost. If you're just
replacing a few
O-rings on a manifold, the system will be 'open' for less than a minute,
followed by
an immediate vacuum. No
Yes that is correct

This is why I have a AC machine, I recover the refrigerant rather than vent it.
As expensive as 134 is I don’t want to lose anymore than I have to. If I charge
up a system and find leaks, I can simply recover the charge, fix the leaks,
pull a vacuum, then charge it again.

Not sure what “Snoop” is, but I’ve never tried the soapy water thing with
refrigerant.
You can buy cheap leak detectors on the Island of Large Wimmen.

(Not so on an old York. Definitely so on many others I've worked on.)
The heat and vibration there seems to be hard on the O-rings. The
manifolds I'm familiar with

Yes. If you're going to save the big bucks doing your own basic AC work, you
need a gauge set
and a vacuum pump. And a dial thermometer, for the vents. It's fairly easy
work,
I agree with Jim. Go the O-ring route first. And yes, I agree that the
“manifold” is likely the low pressure line to between the compressor and
expansion valve.

Basdon your description it sounds like a line needs to be replaced along with
the compressor.
First, you’ll be releasing refrigerant into the air, not a good thing really.
If it’s discharged enough that it’s not making cold at this point, I wouldn’t
worry about it.
You’ll need a manifold

Terminology? In my (limited) experience, the manifold IS the thing that bolts
to the compressor.
Usually there are O-rings there, and that is one of the most common leak points.
It can be
A little over a year ago, after I rebuilt the HVAC box on my 2005 Dodge 2500 Cummins 5.9, I took it to a somewhat reputable shop near me to have them recharge the AC system. They recharged it and then found two small leaks: one leak is on “the AC manifold line”, and the other is on the “rear
