On my '96, it's located on the passenger side of the engine, back and down from
the alternator. It will be very shiny and doesn't look quite like the other pulleys. It's the only
one that contacts the back, or outside, of the belt.
tension pulley is an automatic tensioner that keeps the serpentine belt at the proper tension it is a single pulley that is smooth (no grooves) usually turning clockwise with constant pressure loosens pulley for belt removal use caution pulley is spring loaded
Its similar to the 97 pulley however some advances were made primarily in the metallurgy processes during manufacture, it still retains the tension capability however at an increased pulley factor.

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.
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.
no headlights different
A guide pulley helps to change the direction of a moving belt or cable, while a tension pulley is used to maintain the proper tension in the belt or cable.
The tension equation for a pulley system can be calculated using the formula T 2F, where T is the total tension in the system and F is the force applied to the pulley.
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.

It turned out to be quite simple. The tension pulley is spring loaded. Just put a wrench on the nut of the pulley shaft and you can move the pulley to relieve the tension (do not to loosen the nut) and slip the old belt off. Same procedure to install the new belt. Tension pulley is behind the radiator and a little left of center. Just remove the air intake duct above the radiator. Mine is a '97, but should be similar.
