Look at the diagram which should be on the radiator fan shroud.  This will show you the path the belt takes around the myriad pulleys on the engine.  There is a tensioner pulley whose only job is to maintain the tension of the serpentine belt.  It may be marked on the diagram.  If not, it is the pulley, usually near the top of the engine, that is not the air compressor, alternator, water pump, etc.  I have found that a box-end wrench or a socket wrench which fits the bolt on the pulley, is sufficient.  Just gently swing the pulley away from the belt slightly.  Just enough to release the tension so you can slide the belt off.  You don't have to worry about the bolt coming loose, as it should have far more torque holding it on than you'll put on it to release the belt tension.  Note, that once the belt is off, the tensioner will swing further than it was before, since the belt is not there to stop it.  So when you put the belt back on, you'll have to swing it back down/up to the same position it is in now, if not farther, since the new belt hasn't stretched.

Put a socket with 1/2" drive johnson bar on bolt in center of tensioner and rotate. It's not easy but will go.

How do you replace the serpentine belt on a 1995 Buick century 4 cylinder?


This is the advertised procedure:

REMOVAL & INSTALLATION

Except Serpentine Belt
It may be necessary to loosen more than one pulley or remove another belt to access the drive belt, such as the power steering and air conditioning.
  1. Loosen the driven accessory's pivot and mounting bolts.
  2. Move the accessory toward or away from the engine until there is enough slack in the belt to slip it over the pulley of the driven accessory.
  3. Remove the belt from the engine.
  4. Install the new belt and move the accessory toward or away from the engine until the tension is correct. You can use a wooden hammer handle as a lever, but do not use anything metallic.
  5. Adjust the belt tension, then tighten the bolts.
Serpentine Belt
  1. Place a tool over the tensioner pulley axis bolt.
  2. Rotate the tool counterclockwise to relieve belt tension.
  3. Remove the drive belt.
  4. Carefully release the tensioner pulley and remove the tool.
To install:
  1. Route the belt over the pulleys, except tensioner.
  2. Place tool over tensioner, rotate counterclockwise and install belt.
  3. Remove the tool, then check alignment of tension and belt.

    How simple is it to change a alternator belt on subaru svx?


    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.

    Serpentine belt diagram for a 2003 Chevy unpalatable 4.3


    Pop the hood of the car and locate the serpentine belt routing diagram. The diagram on the 2003 Chevrolet Impala is on top of the fan shroud. The diagram will be a picture of all of the accessory pulleys and how the serpentine belt is routed among the pulleys. This diagram will give you the exact direction for routing the new belt onto the pulleys. If you cannot find a serpentine belt routing diagram, take a notepad and pen and draw out the exact routing diagram of the old belt across the pulleys.

  • 2 Locate the serpentine belt tensioner. It is located below the alternator on the left front side of the engine. The tensioner on the 3.4 liter, 3.5 liter and the 3.9 liter engines will require a 3/8 ratchet to release the belt tensioner. The 3.8 liter engine will require a ratchet and a 15 mm socket for the belt tensioner. Rotate the belt tensioner clockwise to loosen and remove the belt from the belt tensioner pulley.
  • 3 Slide the old belt from the belt tensioner pulley. Remove the belt from the remaining pulleys and pull the belt from the engine compartment.
  • 4 Route the new belt across the crankshaft pulley first. The crankshaft pulley is the big pulley on the bottom of the engine in the center. Then route the serpentine belt across the remaining pulleys as directed by the serpentine belt routing diagram. Leave the belt tensioner pulley for last.
  • 5 Rotate the belt tensioner clockwise again to relieve the tension and slide the new belt across the top of the belt tensioner pulley. Release the belt tensioner and the belt will tighten up as the tensioner applies pressure to the belt. Make sure the new belt is properly seated in all the pulleys.
  • 6 Crank the engine and inspect the belt again to make sure that it stays seated in the pulleys.

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


    Here's the procedure on how to release and replace the tension belt of your car.

    Step 1
  • Open the hood on the Volvo S-60 and find the serpentine-belt routing diagram. The diagram should be attached to the top of the fan shroud that covers the radiator. If not, draw out the exact routing method of the serpentine belt around each pulley with a pen and a piece of paper.
  • Step 2 Locate the serpentine-belt tensioner that is in the very center of the engine. The tensioner will have a square bolt head in the center of the tensioner pulley.
  • Step 3 Slide the open end of the 5/8-wrench onto the square bolt head in the center of the belt-tensioner pulley. Turn the tensioner pulley counterclockwise and slide the serpentine belt off of the tensioner pulley.
  • Step 4 Remove the serpentine belt from the other pulleys and pull the belt out of the engine compartment.
  • Step 5 Slide the new serpentine belt into the engine compartment and around the crankshaft pulley.
  • Step 6 Route the new serpentine belt around each pulley. Turn the belt-tensioner pulley counterclockwise again and slide the serpentine belt around the tensioner pulley. Release the tensioner and it will tighten the belt around the pulleys. Look over the belt to ensure that it is inside of each pulley.
  • Step 7 Crank the S-60 and look over the serpentine belt with the motor running. Let the engine run for about one minute and shut the engine off. Close the hood.
