I bought a new belt and it had a series of diagrams for different engines on the cardboard packaging (ie GM 3.8L). I needed it for my '01 Impala.

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.

    Does the Serpentine belt on a 2006 Chevy Impala need to replaced at say 5 years or any specfic number of miles?


    Serpentine belts can last a long time, they are tough. Much more important is condition. The V ribs on the working 'face' side should be free of excessive cracks. Likewise, the smooth 'back' of the belt gets polished by wear over time but it too should be free of cracks and excessive fraying.

    Serpentine belt has some cracks


    any cracked belt should be replaced. the timing belt drives the cam shaft while the serpentine drives the power steering pump, alternator, water pump, air conditioner compressor, etc. if it breaks in the middle of nowhere, car will get hot real fast and become very hard to steer as you try and find somewhere to pull over. it will also be in the night and adverse weather. so replace it now when it is convenient.

    Removing a serpentine belt to change an alternator


    Easiest way is to release the tension and remove the belt from the alternator and secure it with a bungee cord to someplace that will hold it around the other pulleys. The decal showing the routing should be on the underside of the hood in case it comes off.

    When is the suggested replacement for timing belt on 2001 Chev Impala? Is the timing belt also the serpentine belt?


    the recommended replacement is usually 60 k however i think that belt can go to 100.000 miles, i would not recommend that, because todays driving conditions, the serp belt is a separate belt used to drive the accesories, i.e alt, power steering, a/c and should also be replaced ,however that type of belt can last up to 60.k

    Need to replace the altenator on a 2001 saturn sl1 1.9 liter twin cam


    1)Remove serpentine belt from above with 14 mm wrench on spring
    loaded idler pulley.
    2)Disconnected battery
    3)jack up car and remove passenger front wheel
    4)it helps to also remove the wheel well splash panel also for better
    access.
    5)crawl under car and remove battery and other connectors from the
    alternator. then remove lower attachment bolts (I think there are 2
    below to deal with-one is for a support bar, and one is an alternator
    attachment bolt)
    6)go back up to top of car and remove upper attachment bolt (this one
    is a little hard to get to)
    7)pull alternator out and have a alternator shop repair bad rectifier
    board and any other items that need attention.
    8)reinstall repaired alternator
    9)leave splash cover off to provide additional cooling to the
    alternator area. put wheel back on and lower car.
    10) install new serpentine belt from above and reconnect battery.

    If you have the time you could get the newer improved alternator from
    6th planet. It has shields to improve the heat disipation.

    Thank you Sir, Have a nice day.

    How can i replace the serpentine belt on 2001


    it shouldnt be a bolt it should be a tensioner. i dont think you should be taking bolts off. find the tensioner it will wither be like a 15 mm bolt that is used to move the tesioner or a 3/4th inch breaker bar slot/ratchet slot. you may also want to see at autozone or napa ect if there is some special tool you need for that tensioner.

    Serpentine belt


    This procedure is for anybody who has has trouble getting a serpentine belt on. It's easy and doesn't require a prybar.

    • Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
    • Get the belt around all the pulleys except the A/C compressor or Alternator.
    • The tensioner pulley is near the Alternator toward the center of the engine. It's on a spring loaded arm. Get your socket on the center nut of this pulley.
    • Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt on the final pulley.
    • Slowly release the tension.
    • You're done
