Good poll, it is amazing how many different answers you get to the same question. When I took mine off my 2004 L it took a 1-7/16" open end wrench and standing in front of the truck facing the fan you whack the wrench with a 2# sledge knocking it CCW and it should spin right off. Maybe different years have different size nuts, but I doubt it. By the way, it is an expensive wrench, so if you need to borrow one PM me. Good luck!
