The only thing I did was loosen the plastic clip at the top of the bracket of the AC line , nearest the fuse panel , and push the line to the front of the engine . There should be enough play in the line to squeeze the puller past in order to line it up with the pulley . Be careful when you start to crank the puller to pull it off . Mine got slightly cocked
and actually bent the original pulley and shaft of the puller . I was able to reposition the puller 90 degrees and eventually pulled it off . I hope this helps . Good luck !!!
