You may want to get a serpentine belt tool from Sears Hardware, or Auto Zone. It's a long flat piece of steel with a square drive and attachments for other tensioners.

Need to know how to take the tension off alternator belt to change alternator


There is normally a spring loaded tension pulley that you can release tension on by using a ratchet or breaker bar placed in the square hole on the arm holding the pulley.

How do you change the serpentine belt chevy malibu 200


Well you don't have to remove the tensioner. If you look at it, you'll see a 3/8 square hole in the arm of the tensioner. Put a ratchet wrench, or breaker bar in the hole, and you can move the tensioner, it is only spring loaded. The diagram for how the belt laces in should be on the radiator core support. Lace it for the majority around, move the tensioner, and once you have the belt in line, release the tension on the tensioner arm.

How to take tension off belt to remove alternator


Look right around where your alternator is and you will see a idler pulley that has a square hole in the front of it. You can stick your 3/8 Ratchet in that hole and turn it down to release the belt tension. If there is not a square hole then there should be a bolt on the front you can put a socket on and use your breaker bar to turn the spring loaded tensioner down to remove the belt. To put it back on is reverse of what I told you.

2000 Lincoln How do you adjust the tension on the motor serpintine belt ?


You don't...I mean you can't adjust the serpentine belt because there is automatic self tensioner which loaded by a very high compression spring. Now, there should be a square hole on the tensioner which is a 1/2 inch. You simply put a half inch breaker bar in the square hole to gain leverage in order to change your belt. Hopefully this helps

Cant release tension on drive belt on a 96 chevy s10


The tensioner is spring loaded there is a tool that is made for them that you can get at auto zone or almost any auto parts store. The tensioner will have a square hole in it or you use the bolt that hold the idler pulley on it and just get your tool on it and just put some pressure on it it will move . you don't have to loosen any bolts for it .

  1. REMOVAL
    AIR CONDITIONING BELT

    NOTE: The A/C drive belt self tensioner is NOT a dynamic tensioner. After adjustment the tensioner bracket bolts are tightened. The torsion spring is no longer responsible for tensioning the A/C belt. The torsion spring is only used for initial belt tensioning.
    1. Remove generator/power steering belt to gain access to A/C belt. Refer to GENERATOR/POWER STEERING BELT for procedure.

    1. Loosen BUT DO NOT REMOVE tensioner locking bolt and pivot bolt (Fig. 2).
    2. Insert 1/2" drive breaker bar into square opening on belt tensioner. Rotate tensioner counterclockwise until belt can be removed from pulleys (Fig. 2).
    3. Slowly rotate tensioner clockwise to relieve spring load.
    CLEANING
    Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt.

    INSPECTION
    Belt replacement under any or all of the following conditions is required:
    • Excessive wear
    • Frayed cords
    • Severe glazing
  • Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 3).

    NOTE:
    Do not use any type of belt dressing or restorer on Poly-V Belts. INSTALLATION

    AIR CONDITIONING BELT - NEW

    WARNING: DO NOT REMOVE A/C BELT TENSIONER LOCKING BOLT WITHOUT FIRST HOLDING THE TENSIONER WITH A 1/2" DRIVE BREAKER BAR, AS PERSONAL INJURY COULD RESULT.
NOTE: Verify that torsion spring position is in the new belt position before installing a NEW belt (Fig. 4). If torsion spring is not in the new belt position, follow steps 1-7 to change the tensioner spring from the USED belt position to the NEW belt position.
  1. Insert a 1/2" drive breaker bar into the square opening on the tensioner. Hold counterclockwise pressure on tensioner while removing the locking bolt (Fig. 2).
  2. Carefully release spring load of the torsion spring on the tensioner.
  3. Remove pivot bolt, tensioner, and spring from front timing cover.
  4. Insert spring arm into the NEW belt position on the tensioner (Fig. 4).
  5. Install torsion spring, tensioner, and pivot bolt.
  6. Install pivot bolt. Tighten only finger tight, at this time.
  7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
    1. Install the NEW belt by rotating the tensioner counterclockwise until the NEW belt can be installed on pulleys. See (Fig. 5) for belt routing.
    2. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
    3. Tighten tensioner locking bolt and pivot bolt to 28 Nm (250 in. lbs.) (Fig. 2).
    4. Install generator/power steering belt.
    AIR CONDITIONING BELT - USED

    NOTE: A "used belt" is considered having more than 500 miles of service use. NOTE: Perform steps 1-7 to change the tensioner spring from the NEW belt position, to the USED belt position.
    1. Insert a 1/2" drive breaker bar into the square opening on tensioner. Hold counterclockwise pressure on tensioner, while removing tensioner locking bolt (Fig. 2).
    2. Carefully release the tension of spring on tensioner.
    3. Remove pivot bolt, tensioner, and spring from front cover.
    4. Insert spring into the USED belt position on tensioner bracket (Fig. 4).
    5. Install spring, tensioner bracket, and pivot bolt.
    6. Install pivot bolt. Tighten only finger tight, at this time.
    7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
    8. Install the USED belt by rotating tensioner counterclockwise until belt can be installed on pulleys. See (Fig. 5) for belt routing.
    9. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
