Look at your tensioner pulley it will have a squre cutout that accomodates a 1/2 inch drive ratchet or a 3/8 drive, most likely 1/2 inch. Just insert your ratchet and release in same manner as on the older models....Good Luck

SOURCE: serpentine belt slips off idler pulley

The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.

SOURCE: I need to replace a serpentine belt on a 2001 GMC

it is decieving. if the tensioner has an extension of about two inches from the base, it takes a 15 mm to lift it, be easy, make sure the wrench is not going to touch anything as you release it after taking the belt off

DIY remove/replace serpintine belts on 1997 Buick Park Avenue with Supercharger.


There is no need to remove any bolts from the engine. It is usually easiest to raise the vehicle and remove the right front tire and the plastic splash shield to gain access to the lower engine pullies. It is a TIGHT FIT getting the belts in between the pullies and the fender. All I can say to that is "welcome to the wonderful world of auto repair! - NOW maybe you have a clue why we mechanics charge so much to do seemingly simple things like "just" replacing a little sepentine belt?"
Hopefully, the routing diagram below will help you to get the belts back on correctly.

Need to know timing marks


REMOVAL
1. Disconnect negative battery cable.
2. Loosen power steering lock bolts and nuts accordingly and remove tension from power steering (P/S) and/or air conditioning (A/C) compressor drive belt.
3. Remove P/S and/or A/C drive belt.
4. Loosen generator mounting bolts and adjusting bolt.
5. Remove generator bolts.
6. Remove water pump pulley.
7. Remove crankshaft pulley.
8. Remove upper and lower timing belt covers.
9. Turn crankshaft so that timing mark on timing belt pulley is aligned with timing mark on engine.
10. Check that "I" mark on intake camshaft pulley is aligned with mark on seal plate and "E" mark on exhaust camshaft pulley is aligned with mark on seal plate.
Do not move camshaft or crankshaft once timing marks have been correctly positioned.
11. Loosen tensioner pulley lock bolt.
12. Protect timing belt with a rag.
13. Remove tensioner pulley.
14. Remove timing belt. Mark the direction of timing belt rotation (on the timing belt) for proper reinstallation.

INSTALLATION
1. Install tensioner pulley. Replace tensioner spring whenever timing belt is replaced.
2. Pull tensioner pulley to its furthest point and tighten lock bolt.
3. Check that timing mark on timing belt pulley is aligned with timing mark on engine.
4. Check that "I" mark on intake camshaft pulley is aligned with mark on seal plate and "E" mark on exhaust camshaft pulley is aligned with mark on seal plate.
If existing timing belt is being reused, install belt in proper rotation direction marked prior to removal.
5. Install timing belt onto timing belt pulley first, then idler pulley, exhaust camshaft pulley, intake camshaft pulley, and tensioner pulley in that order.
6. Check that there is no looseness in belt between idler pulley and exhaust camshaft pulley or between intake and exhaust camshaft pulleys.
7. Loosen tensioner pulley lock bolt and allow tensioner spring to apply tension to timing belt.
Do not add additional tension.
8. Tighten tensioner pulley lock bolt to specified torque.

16. Install generator belt and adjust the tension.
17. Install P/S and/or A/C drive belt and adjust the tension.
18. Connect negative battery cable.

INSPECTION
Never forcefully twist, turn inside out or bend timing belt. Do not allow oil or grease to come in contact with timing belt.
1. Replace timing belt if it is contaminated with oil or grease.
2. Check timing belt for uneven wear, fraying, peeling, cracking and hardening. Replace timing belt as necessary.
3. Bend timing belt into a "U" shape as shown in figure. Distance "A" must be at least 1.0 in (25 mm).
4. Inspect both idler pulley and tensioner pulley for uneven wear and smooth bearing operation.
5. Inspect camshaft pulleys and timing belt pulley for broken teeth or damage.
Replace any component that shows damage, excessive wear, or that appears prone to a possible failure.

I'm trying to replace the serpentine belt on a 2002 ford escort zx2 but i can't seem to locate tensioner pulley


It may be like this:

"I just installed a belt on a 1998 ZX2 and used the tension release tool from underneath the car (safely jacked up and blocked) You should remove the right front wheel and plastic splash shield from wheel well (10mm socket). Use the tensioner release tool from underneath and rotate it towards the rear of the engine until you meet the lower heater hose. At this point, have another person use a tire iron / long screw driver, etc. to jam the tensioner pulley in place in order to get another "bite" on the tensioner pulley center bolt (use 13MM socket on the tool) You should have the entire belt pre-routed except for the AC pulley. This is the easiest one to install the belt on once tension has been released. Check for any looseness on the other idler pulleys as well as component pulleys."

Good luck! (rate if useful!!)

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.

    Tension pulley for serpentine belt making noise


    The Tensioner Pulley Bearings are failing and either the Tensioner Pulley or the Tensioner Assembly (Pulley, Arm and Base) must be removed and replaced.

    Click on the following free direct Link. It has several of the Serpentine Belt Diagrams and Tensioners that are possible with your 4.3L V6 engine.
    http://www.2carpros.com/car_repair_information/year/1998/make/gmc/model/jimmy/1998_gmc_jimmy_drive_belt_routing_diagram.htm
    1. Remove the Serpentine Belt.
    "HOW TO":
    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.

    Removing the Tensioner Pulley: See the Diagrams in the Link.
    After the Belt has been removed, with the Tensioner resting:
    DEPENDING ON WHAT TYPE TENSIONER:
    IF the Tensioner Pulley itself HAS a Bolt Head showing, SOME of these bolts can be removed and the Tensioner Pulley replaced.
    IF the Tensioner Pulley itself DOES NOT HAVE a Bolt Head showing, then go to the Tensioner Base located at the end of the Tensioner Arm. This should have a Bolt Head Showing. Remove this Bolt and the whole Tensioner Assembly will com off.

    When replacing the Tensioner Assembly - MAKE SURE you place the protruding "nipple" on the underside base of the Tesnioner into the appropriate cavity on the engine face.

    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

    Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.Com!
