SOURCE: Changing Serpentine Belt on '01 Impala LS (3.8L)

Can u turn the nut in the opposite direction that u have been trying? U need a lot of leverage to get enough tension off to remove the belt. If u have enough room, add a pipe to the end of your wrench, u will need a lot of room to move the tensioner enough. U might have better luck buying the wrench made for that purpose at a parts store. I think I paid about 25 a couple years ago, I couldn't fit a regular socket and wrench on the tensioner, it was a very tight space.

SOURCE: 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

SOURCE: how to release tension on 1995 chevy 5.7L serpentine belt

Look at the diagram which should be on the radiator fan shroud.  This will show you the path the belt takes around the myriad pulleys on the engine.  There is a tensioner pulley whose only job is to maintain the tension of the serpentine belt.  It may be marked on the diagram.  If not, it is the pulley, usually near the top of the engine, that is not the air compressor, alternator, water pump, etc.  I have found that a box-end wrench or a socket wrench which fits the bolt on the pulley, is sufficient.  Just gently swing the pulley away from the belt slightly.  Just enough to release the tension so you can slide the belt off.  You don't have to worry about the bolt coming loose, as it should have far more torque holding it on than you'll put on it to release the belt tension.  Note, that once the belt is off, the tensioner will swing further than it was before, since the belt is not there to stop it.  So when you put the belt back on, you'll have to swing it back down/up to the same position it is in now, if not farther, since the new belt hasn't stretched.

After reinstalling the serpentine belt on a 2004 Chevy impala LS 3.8lt motor, is there a way to adjust the belt tension.


With a non sc
one belt. If you have sc that show two belts.
The picture is non sc. If the new belt is too loose, maybe the tensioner has a problem or you got the wrong belt? Check the accessory pulleys/bearings, see if any movement, the wrong way.

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.

    Timing belt came off on my 2002 chevy impala 3.8, what is causing this to happen?


    That engine does not have a timing belt.

    It does have a serpentine belt that drives the accessories like the alternator, power steering pump, water pump, and air conditioning. Some common things that will cause the belt to come off are the water pump bearing has gone bad, the a/c clutch has frozen, or the tensioner has gone bad.

    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.
