[QUOTE="SVT CAMR, post: 14129026, member: 83181"] After 13 years I re-installed the AC piping and compressor back into my car. I blew all the lines out. I have installed all new "O" Rings and 8 oz. of Pag 46 oil w/ UV into the entire system. I believe my system can take up to 34 oz. of freon. I bought the harbor freight evac pump #96677 that hooks up to your air compressor will pull 24 pounds of vacuum confirmed on the gauge-manifolds I also bought from there #60806. It held all night at that pressure reading. This means the system has no leaks! I must have done something right when installing all the "O" Rings. I have also read it is a good thing after evacuating the system for 45 minutes to close the valves turn off the vacuum pump and let it sit over night and you will eliminate all the moisture in the system. OK I'm ready to fill it! First I have a question. I poured 8oz. of Pag 46 oil with dye into the compressor and the low side line before final hook up. I then evacuated the system. Was this ok to do? Did I hurt the oil when evacuating the system? I assume I'm good to go and will not need freon with the oil additive in it. Please confirm this for me. Ok so what freon to use? Should I just go with the cheapest price as long as it says 134a on the can? Or should I be looking at fancy synthetic advertising with sealer additive? Should I just dump 34 oz. of 134a freon into the system through the manifold set? OR should I buy 2 12oz cans and let the last (3rd) can have a preinstalled gauge on it to tweak the filling process so I do not over fill or under fill? I understand I need to close the high side (Red) valve at the manifold and only fill through the low side (Blue) valve when adding 134a freon to the system. My last question. Will it be ok to fill it in the ####ty cold damp weather were are having in the Chicagoland area right now? Anybody who could answer these questions and give me more insight It will be much appreciated. Thanks Dan [/QUOTE]
