Im about to reinstall the AC system, and im not quite sure what I need to do to make sure it will work properly. I figured I would spray the tubes out with carb cleaner to get any dust out and change the orings so it seals up alright, then just charge it up i suppose.

Im just worried about what a little bit of dust might do, or any potential problems i may not be aware of.

 

You gotta get all the trash and moisture out of the system before charging it. While back I did a 99 Suburban's A/C. I flushed all the lines using REGULAR mineral spirits (not the low odor crap) and dry air to propel it through the lines. Did each line by itself when possible, then the rest of the lines that go to the evaporators (had dual evaporators). A lot of nastyness came out. Then used the proper chemical flush and did it again using dry air to propel the stuff. Then lots of dry air to make sure it's all evaporated and gone. New o-rings, orfices, oil, then vacumed for an hour, then charged.

That's what I always do cause I want the stuff perfect. Oh, and change the reciever/accumulator/dryer thingy.

 

ok i can do that
