Kia Sedona 2002 3.5 lt serpentine belt how to take tension o

There is a speciality tool actually to take the tension of this belt. You can also do it the "old fashioned way" and alow only 1/2 inch of play with moderate pressue at the longest part of the belt(between the compressor and the crank pulley if I remember correctly)
If you experiencing some kind of problem like noise or altinator not charging bring it back to the dealer their are a few "bulletins" or "improvements I've heard about for these problems.
