The quickest and easiest way is to start with taking the hood off. Keep the grille and bumper on.,
Then, in the bottom, there are two screws that holds the radiator to the cross beam, and these have to be loosen up a bit as the AC radiator is kind of squeezed in between the radiator and the cross beam. Then loosen the screvs on the upper side, the hose on the compressor. After that, you should be able to pull upp the AC radiator. Be VERY CAREFUL when you loosen anything from the radiator, as it is in copper and soft. You need to have two tools. One to hold things as they are, and one to loosen the bolt you want. They might need to be heaten up a bit, but again, be careful so you donīt melt the soldering..
