You remove the serpentine belt with a 3/8 ratchet inserted into the automatic belt tensioner and then you have to remove the crank bolt, pull the (crankshaft pulley / vibration dampener) with a special tool > T58P-6316-D < Then re-install crank pulley and serpentine belt and I provided the belt routing (see image) below depending on the engine type there are two different routings.


Basically raise and support the passenger side with jack stand, crank steering wheel full right, remove any plastic covers and you are set. It's not super easy and it does require a special tool, but you should be able to it if you are somewhat mechanically inclined.
