134a question
Does the refigerant come with oil already in it?? Since my conversion I have blown a clutch and when we put a new clutch on the A6 the compressor started Locking up.... should I add oil and refirgerant or go ahead and replace the 30x yr old compressor?

Re: 134a question
you always need oil in the system
some 134 you can buy with the oil added to it, you will need to find a chart to know how much to add  may the forch be with you

Re: 134a question
I thought it had 1 ounce in it but I might be wrong. I have about 50 cans on hand, I can check tomorrow.

Re: 134a question
Thanks Jim,
So if I replace the Drier, and compressor, then I need to add 8fl oz of oil to the system along with the Coolant? Also about how much 134, From what I have seen on my searches this varies.

Re: 134a question
BTW, for the record, I had someone do my 134 conversion, thinking that I did not want to release the freon. They were the ones that I think left the oil out, awfully conspicuous that the compressor would startlocking up after the conversion.
O well, there is 300.00 (after everything is fixed) I will never get back. Funny part is I was over there a few months ago and saw him doing another conversion, he just blead it off with no vaccume just Like I would have..... Any job worth doing... Anyone in the Mebane NC area that is looking to get something like this done PM Me so I can warn you.

Re: 134a question
The amount of R-12 recommended for the system is 3 lbs 4 fl oz for trucks, (Burbs with the rear AC is more). 80 percent of the R-12 capacity seems to be a good starting point (approx. 2 lbs 10 fl oz) but we have had to add a little sometimes.
I would be curious about what others have experienced. Jim |

Re: 134a question
10 - 11 oz of oil is about right. Put half in new rebuilt compressor suction side and half in dryer. Freon put about 2 16 oz cans in with system running. Place thermometer in passenger side vent, turn ac to full blast, close all doors. Start adding a little more freon at a time checking the thermometer with rpms at about 1500. Continue repeating these steps recording the temperature each time. Keep adding a little freon at a time until thermometer starts reading a higher temperature than the previous reading. Then release a little freon until you start getting the lower temperature. This is the amount you want. Too much freon or oil will cause your system to blow less cold.
