a spring loaded
Hard to tell if this question is to:Release the tension on the belt for replacement, orRemove the pulley/tensioner for replacementSee "Related Questions" below for more about doing both
All you do is look for the tension pulley and tighten it, see below
Give the belt a couple of quick, short tugs to relieve the tension. The belt is most likely jammed. Then if it releases, pull it out slowly. If you pull the belt out too fast, it will often lock up. My mistake, I thought seat belt. The pulley that doesn't connect to anything like the crank or alternator is the tension pulley. It is spring loaded. Some have a place for a ratchet to go or you pry against the housing or the pulley itself as long as you don't pinch the belt. Relieve the tension and slip the belt off of another pulley and release the tension.
When looking form the passenger side of the car the tension pulley is on the right hand side. It is the one located in the middle of the "column" (second one down slightly indented to the left)
If your car has a serpentine belt it will have a tensioner pulley. A tensioner pulley is easy to spot. All of your bolt on accessories i.e. water pump, alternator, a/c compressor etc. will have a pulley to run each one. There will be 2 other types of pulleys, a idler pulley and a tensioner. The idler pulley will be a single stationary pulley with a bolt going through the middle and the tensioner pulley will be on a spring loaded piviot.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.

If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley. Pry the idler back and remove the belt.If you are referring to the Serpentine belt, you loosen no pulley. You simply remove tension from the belt. The tension is applied by the Idler Pulley.
