I am in the middle of trying to replace my tensioner pulley. The belt was making a noise, so I checked it out and found the head of the torx bolt has snapped flush with the assembly. I thought it would just slide out, but it only comes out about a quarter of an inch and hits something. Does the assembly slide straight in, or does it need to be angled to install it? Also, did you remove the fan shroud? Looks like mine has a transmission cooler that is attached to the bottom of the shroud with a torx screw. Real tight in there so going to take some doing to get it loose to remove the fan.
Here is a [rather large] image:
