I went to change the belts on my wife's 2012 GMC Yukon Denali with the 6.2 motor. I figured it would have a tensioner like the main belt does, but it doesn't. The old belt has to be cut off and the new one stretched on. $65000 dollar damn vehicle and this is the kind of backwards crap I have to do to replace a belt. I would expect this from some antique vehicle. Apparently there is a special tool you have to buy (of course there is) and install to stretch the new belt on.
Poor mans method that works:
Or you can get a couple of 11" zip ties, 1/2 ratchet, 3" extension and a 15/16 socket. Use your EDC to cut the old belt off. Place the new belt over and behind the crank pulley. Start the belt on the A/C pulley and then place the belt on the top part of the crank pulley. Using 2 zip ties run through the crank pulley and zip tie as much of the belt as possible. Then with your 15/16 and ratchet placed on the crank pulley center bolt, rotate the crank until the belt falls into place.
