You need to change the expansion valve and receiver/drier and all of the o-rings before converting to r134a. If the system is completely empty you will need to add about 4 ounces of Ester oil and about 28oz of refrigerant (r134a).

Re: ef ac questions
Another word of advice. You should replace the reciever/drier also. It has a desicant that absorbs moisture in the system. Once moisture is absorbed it is not released. It only takes 45 minutes of exposure to the atmosphere to saturate this desicant rendering it useless. Moisture in the system can cause freeze ups of the expansion valve and blockages.
