This is really a pretty easy repair. The idler pulley maintains spring tension to keep the belt tight. You will probably find a square hole in the hub assembly of the idler pulley. You can fit your 3/8" rachet directly into the hole, then with only a little force, be able to rotate the pulley in the direction that pulls it away from the serpentine belt. Remove the belt while holding rotational force to the idler pully. Once the belt is off, you can slowly release tension, until your ready to reverse the operation for fitting up the new belt.
