  • non original part you're using?
  • I assume so - lot cheaper
  • might have to space it so it doesn't jam anymore - watch for right belt drive after so
if the original is still in there and jams - you're up for a new one first

Belt won't stay on, 1989 gmc 3/4 ton pickup


Not having the tensioner pulley lined up would do it.
All of the pulleys have to be in a straight line and the tensioner has to keep the belt tight, especially with extra load from one of the accessories.

How to move tensioner on 1991 chevy corsica


The tensioner is the smooth pulley(back side of the belt,no grooves)
Think it's a 15mm bolt, just "tighten the bolt" and the spring loaded tensioner will move The pulley is steel on the 4 cyl, plastic on the V-6 The tensioner bolt is left hand thread so it won't unscrew when you realese the tension.

How do i release the tension belt ... cant seem to find bolt being referred to in other docs


Here's the procedure on how to release and replace the tension belt of your car.

Step 1
  • Open the hood on the Volvo S-60 and find the serpentine-belt routing diagram. The diagram should be attached to the top of the fan shroud that covers the radiator. If not, draw out the exact routing method of the serpentine belt around each pulley with a pen and a piece of paper.
  • Step 2 Locate the serpentine-belt tensioner that is in the very center of the engine. The tensioner will have a square bolt head in the center of the tensioner pulley.
  • Step 3 Slide the open end of the 5/8-wrench onto the square bolt head in the center of the belt-tensioner pulley. Turn the tensioner pulley counterclockwise and slide the serpentine belt off of the tensioner pulley.
  • Step 4 Remove the serpentine belt from the other pulleys and pull the belt out of the engine compartment.
  • Step 5 Slide the new serpentine belt into the engine compartment and around the crankshaft pulley.
  • Step 6 Route the new serpentine belt around each pulley. Turn the belt-tensioner pulley counterclockwise again and slide the serpentine belt around the tensioner pulley. Release the tensioner and it will tighten the belt around the pulleys. Look over the belt to ensure that it is inside of each pulley.
  • Step 7 Crank the S-60 and look over the serpentine belt with the motor running. Let the engine run for about one minute and shut the engine off. Close the hood.

    I can't find the Auto-tensioner on my 99 accord. Does it have one? If not, how do i get the belts off?


    I think this is right, but…
    Find someone to help you if you can. To help hold the new belt in place when you are putting it on.
    Make a diagram of the way the belt fits over and around the pulleys on your car. Don’t thing that you are going to remember where it goes.
    Locate the drive belt auto-tensioner on the upper part of the engine (see pic). The tensioner is an idler pulley, since it does not drive any accessory on your vehicle. Its only function is to give the belt its proper tension.
    Insert a long boxed-end wrench on the auto-tensioner pulley bolt of the appropriate size (probably 14mm) and slowly turn the idler pulley to release the tension on the drive belt (you are not removing the bolt; you are turning the tensioner so you can get the belt off while you have it turned under pressure). If you have a 2.4L engine model (2.3 Vtec should be similar), turn the pulley clockwise; if you have a 3.0L engine model, turn the pulley counterclockwise. Slide the belt off any pulley located on the upper part of the engine while you have the tensioner under pressure; then slowly release the tensioner pulley and remove the belt from the engine.
    Check every pulley run by the drive belt and make sure they are free of dirt, debris and built-up material.
    Compare the old belt to the new one and make sure it is of the same width and configuration.
    Install the new belt beginning with the crankshaft pulley at the bottom and center of the engine and work your way up to the last pulley; follow your notes or the routing diagram on the engine compartment. If necessary, ask your helper to hold the belt stretched next to the last pulley on the upper part of the engine. Using the boxed-end wrench, slowly rotate the auto-tensioner pulley in the same direction you turned it to release the belt. Then slide the belt over the last pulley, and slowly release the auto-tensioner.
    Make sure the belt is properly seated between the flanges of every accessory pulley.

    Timing belt slak


    1. Set timing belt tensioner.
    (a) Using a press, slowly press in the push rod using 100 - 1000 kg (220 - 2,205 lb, 981 - 9,807 N) of pressure. (b) Align the holes of the push rod and housing, pass a 1.27 mm hexagon wrench through the holes to keep the setting position of the push rod. (c) Release the press.
    1. Install timing belt tensioner.


    (a) Turn the No.1 idler pulley bolt counterclockwise to obtain the specified torque toward the left as far as the No.1 idler pulley will go, and temporarily install the tensioner with the two bolts Torque: 18 N.m (180 kgf.cm, 13 ft.lbf)


    NOTICE: To apply the correct torque, apply the torque wrench along the axis through the bolts of the No.1 idler pulley and exhaust camshaft timing pulley.


    (b) Slowly turn the crankshaft pulley 5/6 revolution, and align its groove with the ATDC 60° mark of the No.1 timing belt cover.
    NOTICE: Always turn the crankshaft clockwise.





    (c) Insert a 1.90 mm (0.075 in.) feeler gauge between the tensioner body and No.1 idler pulley stopper.
    (d) Turn the No.1 idler pulley bolt counterclockwise to obtain the specified torque.
    Torque: 18 N.m (180 kgf.cm, 13 ft.lbf)
    NOTICE: To apply the correct torque, apply the torque wrench along the axis through the bolts of the No.1 idler pulley and exhaust camshaft timing pulley.

    (e) While pushing the tensioner, alternately tighten the two bolts. Torque: 21 N.m (210 kgf.cm, 15 ft.lbf)



    (f) Remove the 1.90 mm (0.075 in.) feeler gauge. (g) Remove the 1.27 mm hexagon wrench from the tensioner.


    (h) Slowly turn the crankshaft pulley one revolution, and align its groove with theATDC 60° mark of the No.1 timing belt cover.
    NOTICE: Always turn the crankshaft clockwise.




    (i) Using a feeler gauge, check the specified clearance between the tensioner body and No.1 idler pulley stopper. If the clearance is not as specified, remove the tensioner and reinstall it.
    Clearance: 1.80-2.20 mm (0.071 - 0.087 in.)
    1. Check valve timing.



    (a) Slowly turn the crankshaft pulley two revolutions from TDC to TDC. NOTICE: Always turn the crankshaft clockwise.




    (b) Check that each pulley aligns with the timing marks as shown in the illustration. If the marks do not align, remove the timing belt and reinstall it.
