Mike, the belt routing should be on a sticker under your hood, these use a spring belt tensioner and it is easiest to us a 3/8 or 1/2 breakover to pull the tensioner back then the belt is easily removed and replaced, please do not rate me at all if it is not a fixya, thats the only reason do this is for my score. Thanks, and merry Christmas.

go to www.gates.com on the lower right hand side under popular topics, click on timing belts, then on the left hand side click Parts Locator and Interchange, enter your cars info and the first page that comes up will show you a camera icon for a pic of how your belt is routed. The tensioner pulley is the one mounted on a silver arm, usually at the top. Hope this helps let me know.

Replace water pump belt on a 3.8 chevy impala


You will have to 'untension' the serpentine belt first. Then to reinstall, put the belt on then loosen or 'untension' the belt tensioner. Very simple process. The belt tensioner is the first thing and the last thing you touch when changing the belt. The tensioner will apply tension to the belt after install.

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.

    Need diagram for serpentine belt for chevy imo l s 2003


    Click on the following free direct Link. It has the Serpentine Belt Diagram and Tensioner location for your 2003 Chevy Impala.

    http://www.2carpros.com/car_repair_information/year/2003/make/chevrolet/model/impala/2003_chevrolet_impala_drive_belt_routing_diagram.htm

    GENERAL/Standard Rules to Removal the Serpentine Belt with a Tensioner:
    A. Find the Tensioner(s). (See Diagrams on Link)
    B. 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.
    C. Remove the loosened belt off one of the other more easily accessed Pulleys.
    D. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

    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.

    Alternator belt


    Hi there. If the belt is frayed I would replace it or it probably wont last long. Under your hood should be a belt routing diagram that shows exactly how the serpentine belt has to be routed. Start at the bottom and try to end at the top by the alternator when routing. You have to depress the belt tensioner by placing a wrench on it and rotating it back to get the last bit of play you will need in the belt to get it over the alternator pulley. Its hard to push because its spring loaded so its easier to have a buddy slip the belt on the last pulley well you hold the tensioner back. Just trying to remember here, but I think the belt tensioner is pushed counter clockwise to release and is a 13, or 15 mm wrench. Hope this helps.

    2006 Chevolet Impala Accesory Belt Replacement


    No special tools are required in order to replace your belt. Your vehicle is equipped with a serpentine belt system which means that it uses one big belt to drive all of the accessories. With that being said, all you have to do is place the closed end of a wrench (not sure exactly what size) over the bolt on the front of the tensioner pulley and use it as a lever to push the tensioner away from the belt. once the tension is relieved continue to hold the wrench in place and use your free hand to pull the belt away from the tensioner pulley. After the belt is clear of the pulley slowly let off on the wrench and remove the belt from the remaining pullies. Reverse the process to reinstall the new belt.
