Place a 3/8 drive racthet in the square itting on the tensioner assembly - push to the left (towards passenger compartment). The serpentine belt is now loose and can be removed. To remove the tensioner - loosen the retaining bolt located in the center of the tensioner mount assembly - use a 15 mm socket turn CCW - until it comes out .. When re-installing take notice of the PIN and the SLOT on the mount against the Engine - the pin fits into the slot.. I found that my rachet head would not fit into the narrow space. I used the 3/8" breaker bar that came with socket set that I rarely use. I also used a piece of 3/4" copper pipe (or whatever fits over the handle) to leverage the tensioner easier and allow my free hand to work the belt off the alternator.

To get the belt off, you have to put a breaker bar into the square hole in the tensioner, and either pull up or down. The tensioner spring is what tighten's the belt. It is just three bolts then to get the tensioner off.

The easiest way to loosen the tensioner is to use an automatic belt tensioner. This can be used on a serpentine belt which is connected to every pulley on the engine.belt.

use tensioner to loosen belt. Using a socket, remove the old tensioner..put the new one on and if you were careful, you should be able to slip belt right back in place.

On the tensioner arm there is a bolt holding it there. To the right of the bolt will be a square cut into the arm of the tensioner, use a 3/8 inch socket wrench (no attachment, just the wrench itself) and turn to the right this will loosen the belt to remove it.

use a breaker bar to release pressure on automatic belt tensioner

there should be a square hole in the tensioner arm that you use a breaker bar and an extension in the hole and just turn the tensioner whatever direction that will loosen the belt.

You need to loosen the belt tensioner. There is a large bolt that needs to be loosened in the center of the tensioner pulley. Then the small vertical bolt is turned in the direction to loosen the belt. After the tensioner is loose replace the belt and retension it.

i have the four cylinder. the ac belt has a tensioner. in the center of the tensioner is a bolt/nut. loosen it slightly. under the tensioner looking toward the ground is a bolt head. turning it adjust the pulley. loosen this to put slack in the belt and remove the belt. put a new one on it and remove the slack with the one bolt then tighten the one in the center of the tensioner. be careful not to over tighten

There should be a small square hole near the tensioner pully. A 3/8 socket driver will fit in the hole and then you can losen the tensioner.

Loosen the tensioner pulley. When the tensioner pulley is loose the belt will come off. Put the new belt on and tighten the tensioner pulley.

Loosen the tensioner pulley. The tensioner pulley will slide to the right. This will loosen the alternator belt. So it can be removed.

Place a breaker bar on the lug/hole on the tensioner; then pry against the tensioner.

if by "loosen" you mean loosening the belt then just put a wrench on the nut in the center of the pulley and turn it to the left. its basically spring loaded.
