Excellent DIY overview, but as one who is always analyzing short cuts, I did it my way, and it took less than an hour. I removed none of the items other than fan, shroud and idler pulley, not the whole unit, just the one idler to get belt off. It is a tight fit, so put a protective sheet of card board, or in my case, an old plastic sign which worked great. Since it is a tight fit to remove, you have to protect radiator fins and outside of water connection to alternator, and obviously the connectors, that is it. Also, rather than go through hassle of battery disconnection, just disconnect at engine connection which kills power to engine bay. Took me just about an hour, putting belt back on was the biggest hassle and took a few tries by just replacing idler pulley and leaving it for last and once belt was positioned, put a little leverage on it to align bolt to engine.

Good luck,
