should be a single bolt in the center of the tensioner probly 15mm
Remove the old, damaged idler pulley and replace it with a new one.
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.
You need a 1/2" ratchet or a Johnson bar. The idler pulley has a square 1/2" hole that the square on the ratchet will fit in and allow you to turn the pulley and relieve the tension.
put a wrench on the pulley side of the tensioner (15mm?) and turn. The pulley arm will move & loosen up the belt.
It probably has a tension release pully, not a bolt. The pully has no function except tension. Your repair manual probably has instructions on changing the belt and a photo of the small pulley. Mary
place appropriate size wrench (probably 15mm) on the bolt through the middle of the tensioner pulley and put clockwise tension on it, this will ease the tension on the belt enough to remove it.
pull the tensioner to relieve the tension and slip the belt over the alternator pulley. The tensioner is a spring-loaded pulley below the alternator. The tensioner takes a special tool that fits into a square hole in the side of it. Or you can use an 18 mm socket on the tensioner's pulley bolt. Follow the decal near the right front corner of the engine compartment to route the new belt.
