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.

    Replacing fan belt?what tools are required?


    Instructions

    Things You'll Need
    3/8-inch drive breaker bar
    Metric sockets
    Serpentine belt

    1 Open the hood and inspect the flat surface on top of the plastic fan shroud for the belt routing diagram. Follow the diagram instructions to route the new belt.

    2 Locate the serpentine belt self-adjusting tensioner on the front of the engine block. The tensioner has a pulley on the bottom of the tensioner arm, which the belt travels under. The tensioner can only be rotated from the bolt that secures the pulley to the tensioner arm.

    3 Rotate the tensioner in a clockwise motion with a metric socket and the breaker bar to loosen the tension from the belt. Then, pull the belt off the top of the tensioner pulley. Release the tensioner pulley and pull the breaker bar off the pulley bolt.

    4 Pull the belt out of the accessory pulleys. Then, slide the belt around each fan blade and out of the engine bay. Rotate each fan blade to the top side of the engine to get the belt around each fan blade.

    5 Match both the new belt and the old belt together to make sure that the new belt is the correct size. Then, route the new belt around each fan blade and around the crankshaft pulley. The crankshaft pulley is the big pulley at the very bottom of the engine.

    6 Follow the routing directions from the belt routing diagram to install the new belt around the other accessory pulleys. Once the belt has been routed around all of the pulleys, look over the belt and make sure that it is secure inside all of the pulleys.

    7 Crank the 1998 Dodge Caravan and let the motor run for about 15 seconds. This will finish seating the ridges of the new belt into the grooves of each accessory pulley.

    8 Shut the motor off and close the hood.

        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.

    I need to replace the serpentine belt on my car. How do I do that?


    These instructions will help you . and also the picture below will help you more.
    1
    Locate the belt-routing diagram, printed on the fan shroud or possibly applied to the underside of the hood. This diagram shows you how to properly route the new belt, as well as identifying the location of the various pulleys, including the serpentine belt tensioner.
    2
    Move the belt tensioner off the Sable's belt using the serpentine belt tool. The tool connects to the side of the tensioner's arm and essentially acts as a handle for use in moving the tensioner. You can purchase a serpentine belt tool at most auto-part retailers.
    3
    Slip the belt away from the tensioner with your free hand and release the pressure on the tensioner with the tool. Pull the belt off the rest of the pulleys by hand and then remove it from the engine well.
    4
    Grab the old belt and new belt with one hand and put your foot through the other end of the belts. Stretch them both to their full length and check to ensure their both the same size. The old belt may have up to one-inch of extra length due to normal stretching that occurs during the belt's service life.
    5
    Wind the new belt, rib side to the pulley, around the crankshaft pulley. Consult the routing diagram and route the belt to the next pulley on the diagram. Continue to route and then check the diagram until you have the belt wound around every pulley except the belt tensioner pulley.
    6
    Double check to make sure the belt routes exactly as shown on the diagram and then move the tensioner aside once more so you can route the belt over the tensioner pulley as shown in the diagram. Move the tensioner back into place slowly and remove the tool.

    Good luck

    Change serpentine belt on 06 sienna


    1. 1 Check to ensure the Sienna's engine is cold, then make sure the Sienna is in park, the ignition is in the off position and the key is removed from the ignition to prevent any possibility of the engine engaging during the serpentine belt replacement.
    2. 2 Open the hood and locate the serpentine belt routing diagram sticker on the side of the engine casing. Study it for a moment before removing the existing belt. It is essential the new belt be installed exactly as the diagram indicates.
    3. 3 Find the tensioner pulley, the main pulley that controls the serpentine belt, and fit a 1/2-inch socket wrench over the self-tensioner on the outside of the pulley.
    4. 4 Pull the wrench to the left to move the pulley forward, which loosens the belt, then remove the belt.
    5. 5 Compare the old serpentine belt with the new, replacement belt for length, width and number of grooves on the belt's underside. Be certain the replacement belt is the right part.
    6. 6 Fit the new belt on to each pulley according to the serpentine belt routing diagram on the manufacturer's sticker, or according to the drawing made prior to removing the old belt. Fit the new belt on to the tensioner pulley last, again applying pressure on the pulley's self-tensioner with the half-inch socket wrench to loosen the pulley.
    7. 7 Release the pressure on the self tensioner and allow the tensioner pulley to ease back into place, thereby tightening the new serpentine belt with the appropriate tension.
    8. 8 Remove the wrench and close the hood.
    Thank you and good luck,

    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.

    How to replace my serpentine belt myself


    Well first I suggest that you get a piece of paper an pencil. Draw on the paper the exact position of all your pulley's and then in a different color draw the belt while its on the pulleys mapping out the exact route around each one. Believe me, if you don't and you also don't have the service manual, you will be at it for a while unless you have a very good memory. after that, find the tensioner pully. there should be a 1/2 inch drive opening on the tensioner where you can put a wratchet or a breaker bar. Use a little muscle to move the tensioner away from the belt and when there is enough slack remove the belt with your other hand. Some tensioners have a nut you can tighten to keep it in the "no tension on belt" position. Installation is reverse of removal. I hope this helps. merry christmas
