Automotive Air Conditioning Information Forum

I'm in the process of rebuilding the A/C in my Jeep and, thus far been unable to determine how much oil the system should hold. I'm using a York 209 and replacing the evaporator, drier, condenser and hoses. The York is used, but completely drained of oil. From what I have been able to gather, the drier should hold 2 oz, the evaporator and condenser 1 oz each, for a total of 4 oz. All of the information I have found on the subject says that the compressor should be filled with 14oz. So, if I put 10 oz in the compressor will the 4 oz. in the components add up to the 14? I don't want to overfill the system because of all the problems it could cause. How much oil does a "normal" system hold. It will be filled with R134A.

I Thank You in advance for any help you may offer.

If memory serves me correctly, there is a measuring tool for York compressors. It uses one measurement for vertical mounting and a different measurement for horizontal mounting. We used to be able to isolate the compressor by service valves and open the compressor oil plug and measure the amount of oil. Try your friend at Goggle
