The bolt on the idler pull loosens the normal direction, lefty loosey on the ford ranger 3.0 engine. If you look lower, you'll notice the tension pulley. You can tell it's the tension pulley by the pivoter arm that it's bolted to. Take the proper size wrench or socket, and turn clockwise as if you were to tighten it. It takes a little bit of force, but the whole arm assembly should turn down taking tension off the belt. You can then slide the serpentine off of the idler pulley and remove the pulley.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
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)
The tension of a rope in a single fixed pulley = WThe tension of a rope in a single movable pulley = W/2The tension of a rope in a multiple pulley system = W/ number of pulleys if they are in series.
The tension pulley should have a bolt that holds it on, allowing you to replace the unit.
put it on the tension srewand push back towards muffler
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 will be one of the smooth ones with no ribs.
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
you dont adjust a tension pulley you adjust the position of the compressor to tighten the belt
u need to relaese tension on the tension pulley. this is usually done with a long socket wrench handle. when u release tension and remove belt you then release tension on pulley until you have routed new belt . you then move tension pulley again until you can put belt on it, then release pulley and it will automatically provide correct tension
