SOURCE: how to replace serpentine belt for 96 bonnville

This is a fairly straightforward mechanical procedure. If you will allow me to provide a little perspective first, just so we start on the same page.

Since you ask only for the procedure for replacement, I do not want to jump over the diagnostic element of this process. If you are holding a broken belt in your hand you can skip directly past this paragraph. The serpentine belt, referred to as the engine drivebelt does what fan belts did in the "old days". This belt is by the crankshaft and in turn spins the alternator, the water pump and the pump for the power steering and the air conditioner compressor. This belt is a wear item and should be examined once per year. The belt is smooth on one side and has ribs running long ways on the other side. Using a flashlight check for shiny areas, cracks of any kind or fluid on the belt. Any of these, change the belt.

Now we need to get our navigational landmarks in sync. The engine in most front-wheel drive vehicles is mounted transversely (sideways). So front and back of the engine become left (front of engine) and right (rear of engine). The drivebelt is on the front of the engine, so to your left as you raise the hood and peer inside.

There should be a drivebelt routing decal on the upper radiator panel (between the engine and the front of the car). I recommend at this point that you also take a few pictures of the drivebelt with your cell phone or digital camera. Detail its path around all accessory components. I know that this is belt and suspenders but it will help greatly with replacement. Now look for the belt tensioner under the power steering pump. The power steering pump is at 12:00 o'clock on the front of the engine. Read the sticker on the square power steering reservoir at the top front of the engine to ensure you are in the right place. The tensioner is the round pulley that looks like it it isn't attached to anything and therefore has no purpose. Put the appropriate wrench on the nut on the front of the tensioner and turn counterclockwise (push toward the back of the car). A long handled ratchet works best here since you will need to get some leverage to turn the tensioner. This will loosen tension on the belt. While holding the belt tensioner remove the belt from all of the pulleys and pull it out. When you release the belt tensioner, it will swing down out of the way. Now again rotate the belt tensioner and route the new belt onto the engine. This should do it. If you are going to be doing this intermediate level of repair and maintenance I recommend you get a hard-copy repair manual for your vehicle or subscribe to one of the many excellent repair on-line service. Good luck!

SOURCE: serpentine belt

When you open the hood there is a diagram on a sticker that shows exactly how to do this. Should be on the front lip or the side of the engine compartment. You have to make sure you get it lined back up right and remember to check it once the engine has been started and make sure it running on all the pulleys correctly.

Here is a good diagram that should be able to help in case your sticker was damaged or removed. Good luck!

SOURCE: Serpentine belt too tight to install

I had the same problem when trying to replace the serpentine belt on my 2001 Trooper. The Maintenance book was very vague and I couldn't tell exactly how the tension was taken off the belt, but it did clearly identify the tensioner pulley. I first removed the pulley and looked for some kind of slot that would give me the adjustment I needed, but no slotted adjustment is present on the 01 Trooper. I had to do some research so I pulled of the tensioner assembly and found that there is a spring coil which keeps tension on the belt constant, and eliminates any belt alignment problems.

The Litens style tensioner uses a spring to apply pressure towards the serpentine belt. The way to relax the spring is to use your 14mm socket and ratchet and force the pulley down by driving the pulley nut in the clockwise direction. This forces the spring to compress and the pulley to drop giving the needed clearance to get your new belt in place.

(1999 pontiac grand prix 3100 v6) how do I remove and replace my serpentine belt successfully?


Instructions Things You'll Need
  • 3/8-inch drive breaker bar
  • Metric socket kit
  • New serpentine belt
    • 1

      Park the Pontiac in a safe work area and open the hood.

    • 2

      Inspect the top of the black plastic cover that surrounds the fan for the serpentine belt routing diagram. This diagram has the instructions for installing the new serpentine belt around the accessory pulleys.

    • 3

      Inspect the front of the engine and locate the automatic belt tensioner. The tensioner on the 1999 Pontiac model vehicles is located between the alternator and the crankshaft pulley. The tensioner has a pulley on one end with a bolt head in the center of the pulley. Use the bolt head to rotate the tensioner.

    • 4

      Turn the tensioner counterclockwise with the breaker bar and a metric socket. Pull the belt out from under the tensioner pulley with your other hand. Then, slowly let the tensioner retract until it stops.

    • 5

      Pull the belt out of the other remaining pulleys. Then, pull the belt out of the engine bay and lay it on the ground.

    • 6

      Route the new belt around the crankshaft pulley. Then, route the new belt around the other remaining pullleys by using the serpentine belt routing diagram for instructions.

    • 7

      Rotate the tensioner pulley counterclockwise with the breaker bar and socket. Then, slide the new belt under the tensioner pulley. Slowly let the tensioner retract until it stops. The tensioner pulls all of the slack out of the belt and brings the new belt to the proper tension. Remove the breaker bar and socket from the tensioner pulley.

    • 8

      Inspect the new belt to ensure that it is seated inside of all the accessory pulleys as directed by the diagram. Then, crank the engine and allow it to run for about 15 seconds. Turn the engine off. Inspect the belt again once more to ensure that
      the belt is still around each pulley. Close the hood.

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.).

http://www.2carpros.com/car_repair_information/year/1990/make/pontiac/model/sunbird/1990_pontiac_sunbird_drive_belt_routing_diagram.htm

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:

DEPENDING ON WHAT TYPE TENSIONER:
(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

How difficult is it to change the serpentine belt tension assembly on the 1995 pontiac grand am with the V6? Does the engine need to raised out of the vehicle?


the engine does not have to be raised
.you need a serpentine tool.it is a flat bar with hex cut outs for the pulley.or a shallow socket and ratchet.
the tensioner need to be slack to put on the new belt. draw a diagram of the belt routing of the old belt. the crankshaft is easier put on from the bottom.there is not alot of space and the belt has to be twisted sideways past a few pulleys.

How to replace a serpentine belt on a 2004


  1. Lift the car so you can work from underneath when needed.
  2. Disconnect the battery . Just to be safe.
  3. Take the serpentine belt off.
  4. Remove the alternator.
  5. Remove the A/C compressor. (You can do it without removing, but it's a royal PITA... LOL) Don't unhook the lines, just unbolt and move out of the way.
  6. Remove the worn tensioner from t he block. (You need to unbolt the pulley first to get to all the tensioner bolts)
