Re: Freon amount

you probably should take it to a shop and have it evaced and recharged, that way you know exactly how much is in, I would have a dye introduced as well, in case you develop a leak...have you thought about converting to r134a? It will be cheaper in the long run.....

With either gas use, get the oil in the compressor first. I believe it was 4 oz for compressor. Oil for 134 is differant, called PAG type oil I believe.
With all the new parts , you could go to 134, Your POA valve may have to be modified or replaced to work with this. If you have the evactuator pump and gauges, you can do this at home with 134. It almost requires an act of God to obtain R12. R12 is very high in cost.
Word of caution, don't go using anything like butane or propane or the blend gases.

Re: Freon amount

zdld17 is correct about Freon (R12).

R12 has not been produced in this country in about 10 years. Possibly longer. I spoke to one of my old bosses in the auto service industry and he said he hasn't been able to buy it since the start of this decade. Some people may sell it on the black market but he told me he's not about to go to jail over R-12. If I recall correctly production of Freon was halted by the clean air act. This act took effect on December 31, 1995 or January 1st 1996.

Most auto manufacturers started going with R134-A in 1993.The rest followed in 1994.

P.S. You know what I just did a search for you guys. Here is a good site I found http://www.r-12.com/

1) 1969 Camaro RS 396 TH 400, 12 bolt 3:73 sold 1994

Re: Freon amount

If you are using R-12 evacuate the system first then fill it slowly until the sight glass is free of bubbles. When you no longer see any bubbles the system is full. All of these early systems have a sight glass on the high side. You will need 4 or 5 pounds of R-12. Only use this method if you are using R-12.

I drove it for the first time in 1972 when I was 15.

Better looking than a '56 Ford or Plymouth.
