I replied to the other thread. I should have done a step by step directions but honestly it's not hard. It's just time consuming. Seemed like for me it was one thing after another for the AC compressor. Then the condenser..etc. What I would recommend is removing the front bumper, makes getting in there easier as far as not dinging crap. I have a mid lift in the garage which made things MUCH easier. The compressor itself is only held in there with 3 torx bolts, the hardest part is fishing out the compressor and getting it out, then putting the new one in. It took me several days to do it mainly because of outside things like work or other projects but you could probably take care of it in a day. Make sure you get an O ring kit and change all o rings in the system that you disconnect. It's much easier NOW to change them than to pull a vacuum and find out you have a leak and have to rip the system apart again.
I got my compressor from Rock auto, and also the oring kit. When you open the system up you will need a new dryer. I got mine from autohauz, oem for 40 bucks... then when the condenser nut stripped internally and I got a new oem condenser from Amazon I found out that the new condenser doesn't take the older style dryer cartridge... go figure... $40 wasted for the dyer and 20 wasted for the special tool...
Just be EXTREMELY careful when removing the condenser top nut unless yous is by the under side of the radiator. If you need the tool I will sell it ya cheap since it's of no use for me now. Make sure you fill the new compressor with PAG46 oil. It will have oil in the unit already. DRAIN it out. I think I pulled 120ml of oil from it and then refilled it with 140ml. Because I had a new condenser and dryer so I accounted for I believe 20ml more. If you have the tools this job can be done. I had a lot of people say take it to the dealer because you can't do it...etc. It's not that different from any other car honestly. Just take your time and ask questions. If this is your first time doing it then you will definitely learn some things. I replaced my ac compressor, dryer, valve and misc on my truck two years ago and it's been fine since. As long as you don't have black sludge or metal in the system it should go smoothly.
