to answer your question
you must remove the radiator and fan shroud, then disconect both high side 3/8 lines that go to the condenser , after removing all the refrigerant from the system.......
there are 2 things you can do to get rid of the refrigerant
you can go to any mecanic shop wich normally auto repairs (not an a/c special shop) and for a fue dollars they will remove the refrigerant, or you can go to aa/c specialty pluce and pay up the ass for them to remove it, now problem with a/c specialty place , by law they must remove everything , leaving your system in a vacuum, so when you open (remove) a line it will equal the atmospheric presure and this will defenatly etroduce humidity in there cloging the filter or your expancion valve
THE LAW STATES THAT ANYTHING OVER 10 ONCES MUST BE RECOVERED...... a car system carries 835grams of liquid R134
do the math
