For the 7.3 I use a 150lb torque wrench which gives plenty of torque to release the belt from the tensioner.
For what it's worth I have the idler pulley and it has a little more wear to the front part of where the belt contacts the pulley.
The belt that I replaced has some very minor fraying to the backside of it.
Looking like a tensioner to replace?

I replaced the belt tensioner and will say the new one has twice as much torque as the stock unit. The belt has no rebound now.
When it rains it pours,after I got the new tensioner put on & belt I got to start the engine and it cranked like it wasn't going to start. Come to find out the original alternator gave up the ghost and had to install a new one of those,it's been an adventure!

I replaced my alternator about 15,000 miles ago. I still have the stock tensioner and an old belt. May be time to change.

I spoke to a couple folks and stated that the alternator may create noise/vibration when they go belly up. Could be a 50/50 for the aternator and tensioner for the vibration is gone.
The new alternator is fantastic but the HPOP can't keep up now with the cranking speed
The tensioner is a cheap replacement at $65.
