- Nov 9, 2013soapy water is the old school method. condenser and evaporator can be checked with this method, or pump air into the units with a gauge and watch the pressure. if you have a rear unit ,you have to check the lines under the car.

I once had a ship
refrigeration mechanic check the leaking system of one of my
cars, where despite hundreds spent in shops no-one had found
the two-weeks-to-empty leak previously. He filled up the
system with carbon dioxide gas and raised the pressure 50%
above normal before applying a dishwasher type soap solution
to all tubing surface and especially fittings. After 10
minutes he had located the leak, it almost looked to easy
but apparently was a common practice on the big systems he
usually worked on. Anyone else having experience with this

“sniffer”, I called a “gas leak detector”. I did and
at least two shops did it. The pain continued.

I don't know if your refrigeration shop used a tool we
used to call a "sniffer". It is able to detect
small concentrations of leaking refrigerant especially from
places you can't see.

Yes, the hydrocarbon refrigerant can be used with a dye.
Yes, I have tried
to find my leak using dye. Yes, the dye showed some leaks,
repaired (mostly minor). No, the use of dye did not locate
my elusive 2
week leak. And the AC repair shops did the best they could,
savvy they had, but in the end I was left with a 2 week
duration leak. No
refunds for best efforts.
I have also tried using a gas leak detector with no useful
Given the way the AC unit is installed in the trunk of my
'56 sedan, it is
possible that there is a leak that the dye might have shown
if it were
possible to see behind the evaporator coil. I can't do
This year, I bought a complete trunk AC unit that looks to
be in good
condition. My plan is to leak test this unit out of the car.
If it holds
pressure for a goodly time, I'll swap it with my current
unit. By I, I mean
I will have a shop do this. I can't manhandle that unit
by myself any more.
Too old and puny.
I have one more trick to try before going that route. I
refrigerant AC stop leak that you inject into the system.
It's worth a try.

Is dye compatible with hydrocarbons? Did you try putting dye
in your system
to find the leak ?
