I'd like to get mine working again for now.
My current system is empty as far as I can tell.
I've done a search here and read as much web info as I could. I've found out a bit and I thought I'd check with any of you who might have suggestions for me. Or you could just tell me I'm insane.
Keep in mind that I know next to nothing about all this really. I am just going on what I've read. I feel like a parrot, just squawking what I've heard
I do not plan to upgrade any components, my goal was to just charge the current setup and see what happens. with that in mind a 12r to ES-12a seemed like a good solution. Here is what the site says;
I was going to try the 'Industrial 12a'.
Here is the charge hose they sell with a R12 fitting. It should work with the standard connection to your compressor. No need to change the fittings which I thought was great, it will work with the standard R12 setup.
Here is the procedure as far as I can understand it....
1. Check for leaks or defective components. Check that the compressor has proper amount of lubricant.
2. If desired, pull a vacuum. No more than 10", ES-12a does not become caustic if some moisture is present.Charging under a high vacuum can result in an overcharge. Any overcharge may cause loss of cooling efficiency.
3.Connect gauge and hose with engine off
3.b. Installs as a liquid, they say to invert the can to do so and that it will NOT harm the compressor.
I know this is boring stuff. sorry. I just thought I'd check and see if I have the right idea or if I should go play with my UFO ....
2 cans plus charge hose and shipping $47.00 dollars, seemed to be a resonable cost for a try and see.

- no retro fitting needed
- Completely compatible with all the materials, hoses, O-rings, seals and oils (mineral or synthetic) in all systems
- 6 oz. of Enviro-Safe is equivalent to 18 oz. of R-12 or 16 oz. of R-134a. It is colder than either R-12 or 134a and has much larger molecules that are less likely to leak.

3.Connect gauge and hose with engine off
3a.Connect to low-pressure side of compressor. Not sure about which one this is, I would guess the suction hose side is the low?
3.b. Installs as a liquid, they say to invert the can to do so and that it will NOT harm the compressor.
3c.Establish Flow. After an intial minimum charge is achieved, start engine and set ac to high. Continue to ad to achieve proper pressure level to manufacturer's specifications. (14 psi, 1.4lbs to 1.7lbs, FOR THE SUPRA?)
3d. DO NOT OVERCHARGE, exceeding 60 psig on the low side may damage compressor
3.e Verify pressure and temperatures are correct . Shut of engine, disconnect hose and gauge, install service port caps
note: If a system has been overcharged or has a leak and must be recharged, completely evacuate the system using reclaiming equipment (not recycling equipment) and start the charging procedure over.
