2002 Kia Sedona belt replacing

Engine Mechanical problem
2002 Kia Sedona 6 cyl Front Wheel Drive Automatic

Not finding to me an area this goes to. Hopefully you won't get to upset.

After purchasing a used sedona I decided to do some of the usual maintanince. By usual I mean things usually done when getting as used vehicle. Change motor oil, replace brakes, change coolant, etc. However regarding the issue of replacing the belts that is another matter, to me. There is no diagram showing belt route. No "big" problem. However, what little can be seen from above and below the motor. Either am looking at the tension pulley and don't realize it. Or this van doesn't have one. Therefore the belts have to be adjusted manually.
