I have a 2006 Charger r/t hemi v8. I am trying to replace the idler pulley and I am having trouble removing it. There isn't a bolt in the middle just a small dimple. Has anyone run into this and if so how do I remove it? I hope I'm just missing something really simple. Thanks in advance. I tried to post some clear pictures.

 

Is it an alan head screw, just holding a cover in place??

 

Finally figured it out. It's a plastic cap that I just removed with a flat head screwdriver. Underneath is a T14 Starbolt Socket.
