Kia Sedona, serpentine belt tensioner

First you have to raise the vehicle and remove the wheel from the right front side, next remove the plastic splash shield and from there you will see the tensioner pulley and adjuster bolt (14mm nut). YToun loosen the nut first and then you turn the adjuster bolt counter clockwise untill the desired distance is reached to remove the belt. I believe you can handle it from there?
Goodluck!
