Usualy the tensioner is sold as an assembly-meaning you wouldn't just be replacing the pulley as the springs tend to weaken as often as the bearings going out. If you hear a noise and belt is not rotton/loose and are sure it is the pulley, after you have replacement, note belt routing. Use a socket that fits pulley bolt and move right against spring tension. If left req'd use pry bar. use uppermost tensioner to make it easier. Have helper (or use other hand) to get belt off. Remove old tensioner from block and add new. Replace belt.
To loosen a tension pulley on a 1991 Chrysler New Yorker, turn the nut in the center of the pulley. This will allow the pulley to slide in the cut-out groove so that the belt will loosen.
It is on the front of the crank, under the pulley and timng chain.
The tension on a serpentine belt is automatically set by the Idler Tension Pulley. If you find it is not correctly setting the tension, the the spring may be broken.
With a self adjusting tensioner pulley, there is no adjustment for tension.
you have to push down on the tension pulley, then you would get slack in the belt
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.

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
It is right hand thread. Turn counter clockwise to loosen.
i dont know go to the shop

Adjustment is on the idler pulley with the tensioner bolt sitting right below the alternator. I also had to loosen the center bolt on the idler pulley before it would move.
