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.

    B m w 323 i 2000-01 noise from front of engine at tne top could this be the warter pump


    Possibly, but water pumps on these cars generally leak for a long time before they get bad enough to make noise.
    The more likely culprit is the pulley bearing on one of the tensioners or the idler on the serpentine belt. On the e46, BMW decided not to sell some of the pulleys as separate parts, They sell only the complete tensioner assembly.
    If you do your own work, I suggest the following:
    1) You will want to put on fresh serpentine belts while you are working on it, so go ahead and get some before you start. On-line will be a bit cheaper than the parts store and way cheaper than the dealer. Original belts were manufactured by Continental. You say the noise sounds like it is coming from the top and the idler pulley is the highest one, so I would buy the idler pulley at the same time, it might save you time and a trip later.
    2) Put the front of the car up on ramps and remove the splash shield from beneath the engine. You probably want to remove the air filter box as well to give you another pathway where you can get your hands in there to work.
    3) Make careful note of the belt routes. Perhaps take a picture.. It is physically possible to put the top one one wrong such that it spins the alternator backwards.
    4) With Channel Lock pliers, pull back the tensioners so you can slip the serpentine belts off the pulleys.
    5) Now you can spin all of the pulleys, including the water pump, to see which one(s) are noisy. If you are lucky, you will already have the only new pulley you need (but life is not like that).
    If the pulley you need is not sold separately, you MIGHT be able to save $50 or so if you can find a parts person who is willing to compare your pulley to other pulleys in the parts bins to find a match. Fresh baked cookies are useful bribes for parts people. The pulley need not be an exact match so long as it fully supports the belt and does not touch any other part.

    I want to change the timing belt of my car. Can you give me detailed instructions on how to do it.


    I have pasted the instructions from autozone.com below, but I never recommend this chore for a novice. If the valve timing is not right, it can ruin your engine. If you have not done this before, I recommend you at least have a mechanic look at the belt before you close up the timing cover.


    Removal & Installation

    1.7L Engine
    1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
    2. Note the radio security code and the radio presets. Disconnect the negative battery cable.
    3. Rotate the crankshaft to set the engine at Top Dead Center (TDC) on the compression stroke for the No. 1 piston. The white mark on the crankshaft pulley should align with the pointers on the timing cover. Once the engine is in this position, it must not be disturbed.
    4. Raise and support the vehicle safely. Remove the front tires. Remove the splash shield. Lower the vehicle.
    5. Remove the power steering pump and position it to the side without disconnecting the hoses. Remove the alternator.
    6. Remove the ignition coil cover. Remove the four ignition coils. Remove the throttle cable clamps and harness holder mounting bolts. Remove the cylinder head cover. Remove the crankshaft pulley.
    7. Properly support the engine using a block of wood under the oil pan. Remove the upper bracket.
    8. Remove the grommet from the upper cover. Disconnect the camshaft position (CMP) top dead center (TDC) sensor connector.
    9. Remove the side engine mount bracket.
    10. Remove the crankshaft position (CKP) sensor from the oil pump, without disconnecting the connector.
    11. Apply slight force to the timing belt at the midpoint between the camshaft pulley and the water pump pulley and check that the auto tensioner moves smoothly, if not replace it.
    12. Move the auto tensioner to remove tension from the timing belt. Remove the timing belt.

    1. Set the crankshaft to TDC. Align the TDC mark on the timing belt drive pulley with the pointer on the oil pump.
    2. Set the camshaft to TDC. The UP mark on the camshaft pulley should be at the top. Align the TDC marks on the camshaft pulley with the top edge of the cylinder head.
    3. Install the timing belt in a counterclockwise sequence, starting with the drive pulley.
    4. As required, replace the auto tensioner assembly.
    5. Continue the installation in the reverse order of the removal procedure.
    6. Reprogram the ECM/PCM engine idle characteristics. Be sure all electrical items are OFF.
    7. Start the engine. Hold the idle speed at 3000 RPM-s in park or neutral until the radiator fan comes on or the temperature reached 194 degrees.
    8. Let the engine idle for about five minutes with the throttle fully closed.
    9. If the radiator fan comes on during the five minutes, do not count this toward the five minute programming time.
    10. Set the clock.

    How to change a timming belt on honda civic


    Timing Belt and Tensioner REMOVAL & INSTALLATION 1984–87 Engines
    1. Turn the crankshaft pulley until it is at Top Dead Center.
    2. Remove the pulley belt, water pump pulley, crankshaft pulley, and timing gear cover. Mark the direction of timing belt rotation.
    3. Loosen, but do not remove, the tensioner adjusting bolt and pivot bolt.
    4. Slide the timing belt off of the camshaft timing gear and the crankshaft pulley gear and remove it from the engine.
    5. To remove the camshaft timing gear pulley, first remove the center bolt and then remove the pulley with a pulley remover or a brass hammer. This can be accomplished by simply removing the timing belt upper cover, loosening the tensioner bolts, and sliding the timing belt off of the gear to expose the gear for removal. NOTE: If you remove the timing gear with the timing belt cover in place, be sure not to let the woodruff key fall inside the timing cover when removing the gear from the camshaft. Inspect the timing belt. Replace if over 90,000 miles old, if oil soaked (find source of oil leak also), or if worn on leading edges of belt teeth.

      Fig. 3: Timing belt tension adjustment — 1984–87 engines 86833163.gif
      To install:
    6. Be sure to install the crankshaft pulley and the camshaft timing gear pulley in the top dead center position. Align the marks on the camshaft timing gear so they are parallel with the top of the cylinder head and the woodruff key is facing up. NOTE: When installing the timing belt, do not allow oil to come in contact with the belt. Oil will cause the rubber to swell. Be careful not to twist the belt unnecessarily or bend in a 90°angle, since it is made with fiberglass; nor should you use tools having sharp edges when installing or removing the belt. Be sure to install the belt with the arrow facing in the same direction it was facing during removal.
    7. After installing the belt, adjust the belt tension by first rotating the crankshaft counterclockwise 1/4 turn. Then, re-tighten the adjusting bolt and finally the tensioner pivot bolt.
    8. Replace the other components removed for belt access.
    9. Start the car, check timing and adjust if necessary WARNING
      Do not remove the adjusting or pivot bolts, only loosen them. When adjusting, do not use any force other than the adjuster spring. If the belt is too tight, it will result in a shortened belt life.

    98 plymouth voyager power steering belt


    See diagram
    http://www.fixya.com/uploads/images/C2ED0FB.jpg

    The triangular-mounted AC belt must come off first.
    At the top pulley is a small bracket and hex screw. This is a jackscrew, which when loosened, will lower the top pulley and the belt will become slack. If jackscrew become detached from pulley, just raise pulley by hand to reconnect, and tighten screw to re-thread.
    The larger serpentine belt is loosened by performing a Righty-Tighty to the tensionner pulley. The belt will easily slip off all pulleys. Be sure to follow diagram to install new belts. Remove plastic shield under engine for access to lowest pulleys. I recommend tying up belt above top pulley, threading around everything except tensioner, then untying & position belt over tensionner.
