I found a complete and excellent AC system in a CRX at the local junk yard and will come back tomorrow morning with all the tools to remove it. I will pull everything AC related. Before turning the wrench, I just need to know if there are things I need to be aware of when removing these lines: are any of the lines pressurized? any chemicals to look out for?

Thanks for any tips.

 

Do what I did, just get drunk and pull that out took me under an hour no mess.

 

lol what is it about working on your car drunk that brings out the best in us?

 

Bring two adjustable wrenches. The sizes on the flange-nuts are all wonky.
Bring some WD40 to clean and loosen things.
Wear some googles.

Wait a sec, I didnt know junkyards were allowed to sell systems that were not yet discharged.

Bring a big plastic storage tub... there will be oil leaking from the compressor.

 

and the quickest way to get the AC box from under the dash is to rip the dash out, pry bar and BFH
