Hello all - I had a few cans of R-12 laying around, so I decided to try to add AC back to my car which hasn't had it in about 25 years. I kept the original evaporator, but replaced all the lines and the condenser in front. I rebuilt the factory Nippondenso compressor and vacuumed down the system. It held for a week so I moved forward.
Here in Michigan last night it was about 67-72 degrees, so I attached my gauges, along with a Robinair side-tap (since the tops of the cans are not pretty) and tried to add a full can to the car without the engine running. It took about 1/2 the can and that was it, so I started it up and it eventually took the rest. Then I added a second can and it probably took an hour or so take the second can - with me twisting and turning the can. I'm worried about trying to add the third can. Right now the air is blowing very cold with the 22-24 ounces it has.
Is this normal? Am I missing something?
Thanks,
Howard
