How do i release the tension belt ... cant seem to find bolt being referred to in other docs

remove battery neg lug first. do not yank off alternator wires! until
this step is done first, or boom fire or eat acid.

which engine, we cant guess them here.
my guess H27 v6, wrong the 3.6L


all belts covered on car. (accessory)

here is a real 2007 page
seem you get lost at step 7
right>?


the alternator is NOT adjustable
so why ask this?
the $4 FSM covers this.
under drive belt replacement.

if the post was to remove alternator? is it
do above
then unbolt alt.
end guessing what you are doing....

1. Removing the Serpentine Belt
   • 1 Park your Subaru on a level surface and open the hood.
     
   • 2 Disconnect the ground (black) battery cable using a wrench. This will prevent the cooling fan from activating.
     
   • 3 Locate the serpentine belt routing diagram in your engine compartment and compare it to the actual routing of the installed belt. Make sure the routing on the label matches the actual routing. If they do not match or there is no label, note the actual routing on a piece of paper for later reference.
     
   • 4 Locate the belt tensioner pulley on your Subaru model. If the tensioner is equipped with a squared hole, use a large breaker bar with a 1/2-inch (13 mm) drive. Otherwise, use a ratchet and socket of the proper size on the tensioner pulley center bolt.
     
   • 5 Rotate the tensioner pulley away from the belt to release the belt tension.
     
   • 6 Pull the belt off of one of the pulleys and slowly release the tensioner pulley back into position. Do not let the tensioner pulley snap back or you may damage an internal component.
     
   • 7 Finish removing the serpentine belt from the rest of the pulleys and the engine compartment.
     
   Installing the New Serpentine Belt
   • 1 Match the old belt to the new one and make sure they are of the same length and configuration. It is normal for the new belt to be slightly shorter since the old one has been stretched through use.
     
   • 2 Route the new serpentine belt through all of the pulleys except the tensioner pulley. Use the diagram on the engine compartment or your notes, as a reference, to properly route the belt.
     
   • 3 Insert the large breaker bar into the square hole or the ratchet and socket into the tensioner pulley center bolt.
     
   • 4 Rotate the tensioner pulley in the same direction you did to release the belt tension.
     
   • 5 Slide the serpentine belt onto the tensioner pulley.
     
   • 6 Release the tensioner pulley back into position.
     
   • 7 Look at all the pulleys and make sure the serpentine belt is properly seated on each one. Otherwise, release the belt tension and adjust the belt.
     
   • 8 Connect the ground (black) battery cable using the wrench.
     

You surely can tell the tensoner pulley from the others

There should be a hole to install a ratchet to release
the tension

Removal & Installation

1. Remove the accessory drive belt cover, if equipped.
   
2. Loosen the lock bolt (bottom) of the front belt tensioner.
   
3. Loosen the slider bolt (top) of the front belt tensioner.
   
4. Remove the front side belt.
   
5. Loosen the lock bolt (bottom) of the rear belt tensioner.
   
6. Loosen the slider bolt (top) of the rear belt tensioner.
   
7. Remove the rear side belt.
   

To install:

NOTE Wipe off any oil or water on the belt and pulley.

1. Install the rear side belt, then tighten the slider bolt until the belt reaches the specified tension. Please refer to the following topic: “Accessory Drive Belts”, “Adjustment.”
   
2. Tighten the lock nut of the rear belt tensioner to 18 ft. lbs. (25 Nm).
   
3. Install the front side belt, then tighten the slider bolt until the belt reaches the specified tension. Please refer to the following topic: “Accessory Drive Belts”, “Adjustment.”
   
4. Tighten the lock nut of the front belt tensioner to 17 ft. lbs. (23 Nm).
   
5. Install the accessory drive belt covers.
   

hELLO THERE:
NO YOU DO NOT WANT TO LOOSEN THIS BOLT LOOK FOR THE SMALL SQUARE HOLE THAT A SOCKET EXTENSION FITS INTO THIS IS THE HOLE THAT YOU ARE WANTING TO USE AND THEN PUSH IT OVER TO THE DRIVERS SIDE TO MAKE THE TENSIONER LOOSEN THE TENSION ON THE BELT SO YOU CAN REMOVE IT OK

the one on the engine ?? two bolts either side ,cant remember but yes you may have to remove the fan belt tensioner thinking about it ,quick tip ?? to undo the bottom crank pulley bolt ,use a knuckle bar on socket and jam the knuckle bar into suspension then crank with starter motor ,undoes them everytime it does.Then before you slacken anything to do with the timing ,bring it around to TDC no 1 and paint all the pulleys to the block with white paint ,except the water pump and idlers .

There should be two bolts one at the pivot point other at the tension point might be rusted in positing. Take a piece of wood and try to crack it loose or a rubber hammer to get it that extra force.

As for the other belts there should be a third pully just for tension for the ac and for the power steering just loosing the pivot bolt and the tension bolt and it all should come loose

The serpentine belt tensioner / pulley is on the front of the engine, and part of the belt 'routing'.

Its job is to put tension on the belt as it drives the other devices like the power steering pump, water pump, air conditioning compressor.

It is an aluminum casting that mounts with a single bolt to the engine. The pulley is attached to the arm.

There are a few ways to move / pry the arm inwards, thus releasing the tension on the belt for removing/installing: grab on the pulley bolt (15mm?) with a wrench, or some later models have an opening for a 3/8th socket wrench to attach to directly without a socket.

The tensioner is spring loaded there is a tool that is made for them that you can get at auto zone or almost any auto parts store. The tensioner will have a square hole in it or you use the bolt that hold the idler pulley on it and just get your tool on it and just put some pressure on it it will move . you don't have to loosen any bolts for it .

1. REMOVAL
   AIR CONDITIONING BELT
   
   NOTE: The A/C drive belt self tensioner is NOT a dynamic tensioner. After adjustment the tensioner bracket bolts are tightened. The torsion spring is no longer responsible for tensioning the A/C belt. The torsion spring is only used for initial belt tensioning.
   1. Remove generator/power steering belt to gain access to A/C belt. Refer to GENERATOR/POWER STEERING BELT for procedure.
   
   
   1. Loosen BUT DO NOT REMOVE tensioner locking bolt and pivot bolt (Fig. 2).
   2. Insert 1/2" drive breaker bar into square opening on belt tensioner. Rotate tensioner counterclockwise until belt can be removed from pulleys (Fig. 2).
   3. Slowly rotate tensioner clockwise to relieve spring load.
   CLEANING
   Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt.
   
   INSPECTION
   Belt replacement under any or all of the following conditions is required:
   
   • Excessive wear
   • Frayed cords
   • Severe glazing

• Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 3).
  
  NOTE: Do not use any type of belt dressing or restorer on Poly-V Belts. INSTALLATION
