2003 VW Jetta Serpentine Belt

Are the serpentine belts directional? I installed a new belt and followed the path correctly but now during exceleration I have a sound being made like a fan is blowing. I have no performance problems at all.

    I have the same issue. I recently did a timing belt job and now have a strange swishing sound when I accelerate. Any ideas? It sounds like a fan blowing and my car sputters a bit when I push on the gas.

Is it a squeal noise or what? explain more in detail. and yes the belt is directional in that it's path is designed to run in one direction only, no matter which side you put on the belt itself, the belt can be installed in one way or flip it over to the opposite side...doesn't matter, only matters if you installed it correctly on the routing of the belt. And the grooved edge is to be facing down inside the main pulley's that have grooves. If you have the smooth side down into the pulley grooves, remove teh belt and turn it inside out so that the smooth side does not ride inside the grooves of the pulleys.Sometimes, the tensioner pulley will squeal or the idler pulley will squeal when they are going out. If you are actually hearing the fan come on and off, that's normal, the fan is set up to turn on and off according to engine temperature and some cars they continue to run for a bit after ignition is turned off as well to cool the engine down. check to see if the belt is set all the way on all the pulley's it rides on and not partly off on the edge, realign as needed.

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.

    Serpentine belt routing


    Hi,

    The detailed solution provided below will be of great help to you,just follow the steps carefully;

    1.Raise the hood of your Subaru and support it with the prop rod. Locate the negative battery cable at the negative battery terminal. Remove the retaining bolt from the battery cable end with a wrench and separate the cable from the terminal.
    2.
    Find the serpentine belt tensioner on the front of the engine and place a socket on the apex bolt in the center of the idler pulley. Attach a breaker bar to the socket and rotate the tensioner clockwise until the belt is loose, then remove it from the pulleys. Rotate the tensioner back to the home position and let it sit there for now.

    3.
    Install the new serpentine belt over all the pulleys except the tensioner pulley. It is important that the belt follow the correct path over the pulleys. If you are unsure of the path, look for the sticker under the hood with the belt-path diagram on it.

    4.
    Rotate the tensioner clockwise far enough to install the belt around the pulley on the tensioner, then slowly rotate the tensioner back to the home position. The tensioner will tighten the belt correctly and no adjustment is required.

    5.
    Install the negative battery cable back on the negative battery terminal and install the retaining bolt. Tighten the bolt with a wrench, then close the hood.

    Problem solved,

    Good luck!!

    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.

    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.

    Is it easy to install serpentine belt on 2003 grand prix?


    Yes - fairly easy..

    First - study and WRITE DOWN the belt path... Draw it.. What ever it takes.. Once its off - it can be confusing to remember..

    Then - on the tension pulley there is a bolt in the center.. Put a closed end wrench on it it and push real hard in the direction that would relive tension on belt (usulaly downward).. It will slide right off..

    Get the new one in place of correct path and push the tension pulley again to get belt on all the way and release tension pulley and it will be tight..

    Note; The tension pulley is spring loaded and keeps the belt tight..

    Have a great day !

    '93 Mercury Sable Serpentine Belt installation without using AC


    You need to have an automotive technitian install a new belt because there is a certain path the belt must follow before it will go on, plus the belt must go around the A/c as it is part of the path. You just don't have to use the A/C.

    Tell the tech that the belt broke so that he can look for a reason as to why the belt broke.
