You won't lose much at all, it won't need bleeding if you're quick. When I did mine it was airbox out, disconnect top hose from radiator & bend it up out of the way, I only lost a bit from the rad, maybe cable tie a nitrile glove or small bag over it? I also removed (or loosened, can't remember) the bracket holding the A/C lines in place. I had read it can be removed from underneath too, but I didn't do that as the bolts were breaking the plastic undertray. A very simple job to do.
