Changed mine tonight in less than 30 mins. For whatever reason the tool sizes are a bit different on our cars (Might be a 2014 thing). You need a T55 torx bit and a E14 instead of the T50 and E10/12 the F30 guys are referencing in the instructions. I also used a 5/32" R lock pin for a trailer hitch to lock it out of tension. Didn't do the idler pulley yet, since it's on order and mine felt fine on inspection. Used these instructions from Badbread
http://*************/tensionerdiy/ with the different sizes for our cars. He pulled the lock pin out of the new tensioner with force, but if you crank the new tensioner the same way you lock the old one the pin comes right out.
