SOURCE: serpentine belt

it is on a sticker adhered to your radiator shroud.
if it is removed, damaged, or unclear...

one tip - if you look by the crankshaft pulley to the right you will see a tubular looking shaft about 1" diameter , you will notice you can't get the belt out from under this piece , it has a nut on it , once you take the nut off , you will notice it has a star shaped point on the tip of the stud , it requires a reverse torx socket or wrench to remove the stud , when you get the stud out the tube piece it can be removed , then the belt comes off , replace the belt , now comes the tricky part , fitting that tube spacer back into its spot , it can be difficult , once its in place put the stud back in , and put the nut on and tighten it.

SOURCE: how to install serpantine belt tensioner on 2000 pontiac grand am

Basically, Remove the belt. Then remove the bolt that the tensioner pivots on and remove it. It's fairly easy.You may need to remove the belt pulley to make it easier.
The problem comes as your trying to get to it. If you can't see it well or something is in the way. Like the plastic overflow tank or something like that. Then you will need to remove what is keeping you from getting to the tensioner. I did one on a four cylinder last week. The belt pulley on that one had a left hand thread. The tensioner itself should be right hand thread.
Good luck.

Where is the tensioner pulley located on a 1994 pontiac bonneville? and how do I adjust it to get the alternator back on? Thanx

the tensioner is located directly below where the alternator bolts on. it is an automatic adjusting tensioner so you can't adjust it . you can only move the pulley back and forth to allow slack in the drive belt.

(1999 pontiac grand prix 3.1 v6) when I turn my engine on, should my belt tensioner move at all? It moves a bit

its suppose to move up to 1/2", it is spring loaded!! Now if its squealing or chirping at startup or when the engine is revved, the tensioner is probably worn and needs replacing along with the belt!!

How to change the serpentine belt. a diagraham

Welcome to Fixya

Here's the procedure on how to replace the serpentine belt. I am sorry if cannot provide you the diagram.

1. Open the hood and locate the serpentine belt routing diagram. The diagram is on a sticker originally adhered to the fan shroud or the underside of the hood for easy referral when replacing the belt. If the sticker is no longer on the Pontiac, you'll need to get one either from your local Pontiac dealer, in the Pontiac's specific service manual or online. Or you can draw a diagram of your Pontiac's pulleys and belt, showing how the belt routes around the pulleys.
  • 2 Insert the tip of the belt tensioner tool into the corresponding notch on the serpentine belt tensioner. You can locate the tensioner by looking for a pulley located at the end of an arm. This arm and pulley assembly is the tensioner.
  • 3 Pry the tensioner arm away from the belt face with the tensioner tool. On some Pontiacs you can substitute a large socket wrench, but the risk of damage to the tensioner increases greatly with the socket wrench. The price of a tensioner tool is far less than that of a new tensioner, so avoid the socket wrench and buy the proper tool at your local auto parts store.
  • 4 Push the belt off the tensioner pulley with your free hand and slowly move the tensioner back to its relaxed position. Pull the tool out of the tensioner and set it aside for now.
  • 5 Pull the belt off all the pulleys and lift it up out of the engine well. Depending on the year, make and model of Pontiac you are working on, you made need to access the lower pulleys from below the engine well or through the wheel well to get the belt out.
  • 6 Stretch both belts out to full length to make sure the new belt and old belt are nearly identical in length. The new belt should measure less than an inch shorter than the old one. This is due to some stretching the old belt received during its lifespan.
  • 7 Route the new belt around the pulleys, beginning with the crank pulley and working your way up until the tensioner pulley is the only one left. Make sure to consult the routing diagram frequently during this step. If you route it improperly, you will have to either take it off and start over, replace whatever component this damages from the improper routing, or seek first aid for the injuries you suffer.
  • 8 Plug the tensioner tool back into the tensioner body and lever the tensioner pulley away from the belt path once more. Pull the belt over the tensioner pulley and hold it there with your other hand as you slowly release pressure on the tensioner. Take the tool out when done.

    I am replacing the Water pump and cant get the tension off the drive belt on my 2003 Pontiac Bonneville 3.8 L

    You have a spring loaded belt tensioner on the serpentine belt. If it loads on top of belt you need to unload it by raising it upwards or if it loads under belt you need to lower it. It either has a square hole in it that will fit a 3/8 or 1/2 ratchet or breaker bar or it will have a hex head that you can use a socket or box wrench.

    How do I change a serpetine belt on a 1999 Pontiac Bonneville ?

    be sure to view the belt diagrahm...locate the tensioner pulley and insert the drive end of your 3/8 drive ratchet into the square slot in the tensioner...move your ratchet clockwise, you should see the belt loosen...then lift off, when replacing with the new belt...install over will need to twist the tensioner pulley with the ratchet to install over the final pulley...release and belt should remain tight...again check the belt diagrahm for belt accuracy before test running...:)

    How do you replace the serpentine belt tensioner on 1990 sunbird 2.0 ohc

    Click on the following free direct Link. It has several of the Serpentine Belt Diagrams and Tensioners that are possible with your 2.0L 4-Cylinder engine and engine options (AC/No AC, etc.).

    A. Remove the Serpentine Belt.
    "HOW TO":
    Standard Rules to Removal the Serpentine Belt with a Tensioner:
    1. Find the Tensioner(s). (See Diagrams on Link)
    2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
    3. Remove the loosened belt off one of the other more easily accessed Pulleys.
    4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

    B. Remove the Tensioner:
    Removing the Tensioner Pulley: See the Diagrams in the Link.
    After the Belt has been removed, with the Tensioner resting:

    (1.) IF the Tensioner Pulley itself HAS a Bolt Head showing, SOME of these bolts can be removed and the Tensioner Pulley replaced.
    (2.) IF the Tensioner Pulley itself DOES NOT HAVE a Bolt Head showing, then go to the Tensioner Base located at the end of the Tensioner Arm. This should have a Bolt Head Showing. Remove this Bolt and the whole Tensioner Assembly will come off.
    (3.) Some Tensioner Assembly's need you to locate and remove mounting bolts.

    If Applicable: When replacing the Tensioner Assembly - MAKE SURE you place the protruding "nipple" on the underside base of the Tensioner into the appropriate cavity on the engine face.

    Standard Rules for Installing the Serpentine Belt with Tensioners:
    a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
    b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
    c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
    d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
    e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them

    Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.Com!

    Thanx for diagram, where do i start on changing serp. belt on 1996 bonneville?

    Crank the tensioner over so that you have some slack in the belt and pull the old one from one easily accessible pulley. Pull the belt off the pulley system and put the new one on following the diagram. Crank the tensioner again and use a screwdriver to pull the belt over the uppermost pulley. Release the tensioner and check belt tension.
