I had posted a few days back that my air conditioner stopped working -- in spite of the fact that it had a good charge of Duracool.
Checking the high side of the compressor I found that I was only getting approx. 100 psi which was low.
I purchased an air conditioner from Jim Kanomata. It was a new one that he is carrying. It is aluminum and weighs 17 pounds. That is compared to the original which weighed 34 pounds.
It didn't come with any instructions except a slip of paper in the box that said it was filled with 7.43 ounces of PAG 46.
Since PAG 46 is death to an air conditioner system filled with mineral oil (the Internet says it will react and form a peanut butter like paste inside the air conditioner system), I drained the compressor, flushed it out with mineral spirits, drained that and put in 7.4 oz. of mineral oil. BIG MISTAKE!
When I charged with Duracool I got no cooling. After thinking it over, I decided that the 7.43 oz. was likely what the whole system needed but since I was leaving my dryer, condensor and evaporator in place they already had oil in them. So, I released the Duracool through the high side fitting in order to deliberatly purge off some oil. I heal a rag around the fitting and let the oil drip into a jar. After I figured that I had about 3 or 4 ounces I was also our of charge in the system.
I evacuated the system and refilled with three cans of Duracool and I now have cooling! I will fine turn the charge later when it is not 90 degrees out as it is today.
The high side is now 170 psi and the low side is about 30 psi at 1500 rpm. That is going to be close to the right charge.
I will soon be writing up an installation procedure for Jim to include in the boxes he ships out with the new compressor.
I was really thinking of installing a Sanden but didn't know where I could get the one with the GMC rear fitting in a short amount of time. We are leaving for a GMC Mountainaires rally before this next weekend.

Look forward to seeing the write up Emory. The way the original compressor mounts is....ah...difficult and complex to say the least. I'd almost change it out if I had to remove and reinstall again.

Not exactly related Emery, but I have used Duracool since before moving to
AZ. One of my motorhead friends here is a GM certified AC technician and
there is no way I could convince him about the benefits of Duracool
(HC12a). Recently, his Cadillac AC died and it is an older R12 system. R12
here is over $50 a can so economics has forced him to swallow his previous
feelings about refridgerents and he stopped by to check out the Duracool.
I keep a couple of cases in the shop. After reading the spec sheet, he
left with three cans. I got an email from him and his Caddy is blowing 18
deg on the road on a 90+ deg day and he is one happy camper. His greatest
achievement with R12 was 24 deg. He swears by the stuff now. It has been
fun.

Mickey.
I like to fill to 20 psi at 1500 rpm when the ambient temperature is around 80 deg F. ;however when it's very hot out it tends to be a higher pressure and if you have been running the engine for a while the condenser gets quite hot.
That is why I said I would fine tune it later as it was a very hot day when I was working on it

Yes, I will be there. Chuck Boyd is usually there with his gauges and vacuum pump as well
I had ordered two cases of Duracool but have used 6 cans to do my system. I will bring the other 18 with me.

Howard,
If you're A/C evaporator has frost on it the temperature of the refrigerant in the system is too cold. If the evaporator freezes
over sold you could return liquid refrigerant to the compressor and it doesn't like that as it is designed to compress a gas NOT a
liquid.
Ref: http://auto.howstuffworks.com/automotive-air-conditioning.htm
Copied from page #3:
The evaporator also takes humidity out of the air in the car, which helps you feel cool. Water in the air condenses on the
evaporator coil, along with dirt and pollen and anything else floating around in the cabin. When you stop the car and see water
dripping underneath, it's probably the water from the AC evaporator and nothing to worry about.
Regards,
Rob M.

That's normal.
Have you ever stopped your a/c car, truck or GMC on a hot day only to see water dripping out from under your ride.
That's the frost melting off the a/c

Well then my 85 El Camino and Susie's Durango the A/C most be broken.
On high humidity days I see water on the ground and sweat on the dryers when I open the hood.
Thanks

All evaporators will condense water especially on a humid air. That is why manufacturers build in a pan under them with a hose running from the pan so that the water will drip on the ground.
Rob is correct that if the evaporator freezes up it is too cold and with Duracool that means too low a charge.
The dryer (accumulator) should not sweat though as it is fed by the hot vapor from the compressor. Then it flows to the condensor which cools the hot vapor some so that it turns into a hot liquid. That passes through the expansion valve and flashed off to a cold vapor which picks up heat from the evaporator and then returns to the compressor.
If you dryer is sweating that usually means that you are low on refrigerant which allows the vapor to expand and cool when it enters the dryer instead of when it leaves the expansion valve. If you put in more refrigerant it should act as normal (unless, of course, your compressor is going bad).

I have never messed with the Durango.
Dead stock
Dodge must have messed up
The El Camino I replaced the compleat system after the compress was eaten up by R134
I will never use R134 again
That stuff is nasty.
Thanks

Emery let us know how this new compressor performs compared to a good A6 once you get some miles on it. Is it the same tonnage? I understand the weight saving and package size improvement, but an A6 is a proven and powerful unit. Did yours have a lot of hours on it when it got weak? I'm guessing bad ring sealing it a bad valve giving the low output. Is HC12 benign to mineral oil stability long term?
