Belt Tensioner and Idler Pulleys Torque Spec

Hey Y'all,

New to the EcoDiesel community and I own a 2016 with about 124k on it.

Gotta do some maintenance to it and I realized that I gotta get the belt changed before it wears down and we have problems. Cannot seem to find anyone who has changed out the serpentine belt, belt tensioner, and idler pulleys. I need the torque spec for the idler pulleys and belt tensioner...but not even YouTube could solve this. I guess people just change the belt and call it good? Not sure if I should even change the pulleys & tensioner...maybe only do that if they fail? I thought it would be better to replace all since you're in there anyway and for tension purposes
