John Deere...I've seen freeze 12 a number of times. It mixes with R12 perfectly and does a great job. You'll never know you have anything but R12 in your car.

we had the old stuff dumped in the bonneville and replaced with freeze 12. it did the job, but wasnt as cold as it had been in the past.

May not have been working optimally. I've had it in my cars and it rocks.

Well this stuff turned out to be a real hassle. First, my car has some dumbass high side fitting that i had to go find an adapter for, then the adapter wouldn't depress the modified schrader valve on the car'* fitting, so i had to make more modifications.

Next, I emailed the Freeze 12 company to ask which type of can tapper it takes for a Freeze 12 can, to which they replied "the kind that squeezes around the can, not the type that screws on the can." This is good, i think to myself because i have such a tapper, so i ordered 6 cans on ebay. When they got here, lo and behold they require the Screw-on can tapper. Now i can't just buy the freeze 12 tapper and fittings because they won't attach to my guages and vacuum pump, so i'm screwed. I went out and found some fine threaded nuts that would fit on the can and on my tapper and welded them together and was able to make my tapper fit on the can perfectly, with no leaks.

Next it was time to evacuate the system so i put the vacuum pump on for 15 minutes and everything'* well and good, so i attach the can, and the stupid R-12 tapper that i just modified is leaking on the other end of the hose. So i cut the end of the hose off and found a hose barb and some spare fittings and made a new hose end, and then everything worked fine and i had no trouble charging system.

You're supposed to use 10% less Freeze 12 than R-12, so i added three 12oz cans. It seems to work great. The air coming out the vents is 43* F at 75* ambient. I went and checked our chrysler van and it is 51* with R134a, so i'm quite happy.

The real test of this stuff will be if it ever ruins my compressor. If it does, i'll let you know.
