You dont adjust the tension on a serpentine belt, Dodge uses a spring loaded tensioner located just below the alternator, If your belt is loose it is either worn, the wrong size belt or your tensioner has frozen and not moving. If it is a brand new belt I would suggest making sure the correct one was given to you from the auto parts store. If the belt has been on the vehicle for an extended period of time I would suggest replacing it.
you dont, it has a spring loaded tensioner

Not sure ,but it costs $115 to change mine on my 1998 Dodge Durango.
Done automatically by belt tensioner
Serpentine belts have a pulley that is spring loaded. Tension is set automatically when the belt is installed.
You don't. If it has stretched too much for the tensioner pulley to handle, you need a new belt. Or, if the tensioner pulley is not applying correct tension, the tensioner pulley must be replaced.
Dodge Durango was created in 1998.
You don't. The serpentine belt tension is automatically maintained by the tensioner pulley, which is an idler pulley located on the passenger side of the system and looks like it doesn't drive anything. If the belt tension is incorrect, the tensioner pulley must be replaced. If the question meant 'how to release tension from the belt' (for removal, etc.), this is done by applying the correct size socket wrench to the tensioner pulley's center nut and rocking the pulley away from the belt.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
