The tensioner is a moving part and can wear out like any other mechanical part, however, there is one bolt in the front of the tensioner pulley (15mm) that holds the tensioner in pace. Make sure that it is tight, no play in the part.
There really is no "tightening" of the belt because that is the tensioner's job. If your belt is loose or squeaking you may want to replace the part. That is what I am doing. I have a 2004 Ram 2500 4x4 w/ 5.7L HEMI and am replacing the tensioner. There are 80K miles on the rig and I maintain it meticulously. Troubleshooting the consistent squeaking after the belt r&r I decided it is the tensioner and my mechanic conferred.
Oreilly's has the OEM part for $45 (Dodge HOUSE IS $75.00) and it will take 20 minutes to change the tensioner and reinstall the new belt.
Here are instructions for a 2004. There should be little, if any difference.
First you need a breaker bar and 19mm socket to fit the "tension bolt". Turn tension bolt clockwise to release tension in order to remove the serpentine belt.
You can remove the old serpentine belt on your 2004 Dodge Ram by loosening the tensioner pulley. Put the new serpentine belt on and tighten it with the tensioner pulley.

They are not adjustable and must be replaced if defective.
if belt needs tightening, u need a new belt serpentine belts use a tension pulley that automatically keeps belt tight until belt is worn out or stretched.
Idle is computer controlled and is not adjustable.
There is not an adjustment on a flywheel. Your problem will most likely be the starter.
they are not adjustable they are sealed units
