Mazdaspeed 3: Idler Pulley Replacement.

I originally wasn't going to post a video so forgive me for the out of order sequence.
I used the video ‪@everythingdiy‬ posted for a tensioner pulley and serpentine belt replacement which was golden. Like her I also had issues getting the belt back on so I figured out a different way. hopefully this is helpful to anyone that had the same issues as me.
This install is specifically on a 2013 Mazdaspeed 3.
