Picked up the 2008 Pulley for my 2007. Looking at the install process and I am wondering how most members are tackling this mod. From up top or below? If from up top, what components are you guys removing to accomplish this and what type of puller and installer are most using. I know the location of the SC tensioner but where is the auxiliary belt tensioner located? A step by step approach would be most appreciated. I have the torque steps and settings from the Shop Manual.
