Tool required to replace serpentine belt on 1997 Ford 4.6 liter e

What tool is required to release the tension on the belt. The diagram on the 1997 Ford F250 shows a square hole in the tensioner, but it is not square. It feels round. I can't get a good look at it. On the diagram it says to use the lug adapter. What is that?

F-250 Belt Removal

  1. Install a 16-mm (5/8-inch) closed end wrench for 7.5L engines or a 15-mm (19/32-inch) closed end wrench for 5.8L and 7.3L engines on the tensioner pulley bolt and lift the tensioner arm away from the belt.
  1. Remove belt. Release tensioner arm slowly. Do not allow arm to snap back after the belt is removed because this may damage the tensioner.

    Okay... sorry for missing the other engines. Perhaps you are looking at the wrong end of the tensioner?



    I'm trying to post a diagram, this is my first attempt. Apologies if the diagram does not display properly. If not, the head of a 1/2 inch drive ratchet (or 1/2 inch breaker bar or belt tensioner tool) should fit.



    4.6L & 5.4L with A/C


    1. Use the (B) 1/2 inch square hole in the drive belt tensioner pulley hub to rotate the (A) drive belt tensioner clockwise and remove the (C) drive belt.



      4.6L & 5.4L without A/C
      Removal


      1. Use the (B) 1/2 inch square hole in the drive belt tensioner pulley hub to rotate the (A) drive belt tensioner counterclockwise and remove the (C) drive belt.

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.

    How do you replace the serpintine belt on a 1998 contour?


    Open the hood and locate the belt tensioner. The serpentine belt drive is located on the front of the engine on the passenger side of the engine compartment. The spring-loaded belt tensioner on the 1998 Contour is located slightly to the left of and below the water pump pulley
    Release the tension on the belt using the serpentine belt removal tool. On vehicles equipped with the 2.5 liter V-6 engine, snap the 3/8 inch-drive adapter onto the removal tool. Slip the tool into the square, 3/8-inch hole in the end of the tensioner arm. Rotate the tensioner clockwise to release the tension. While holding the tensioner back, remove the belt from one of the pulleys. Release the tensioner, remove the belt from the remaining pulleys and pull it out of the engine compartment
    Snap a13 mm socket adapter into the belt removal tool for the 2.0 liter, four cylinder Contour. Place the tool onto the 13 mm bolt that holds the tensioner pulley to the tensioner arm and rotate the tensioner clockwise. While hold the tensioner back, slip the belt off one of the pulleys. Release the tensioner, slip the belt from the remaining pulleys then remove it from the engine compartment
    Route the new belt around the pulleys, according to the belt routing guide. The belt routing guide on the 1998 Contour is located on a decal on the left (passenger side) strut tower. If this decal is missing, or unreadable, the belt routing guide can also be found in your service manual. Rotate the tensioner pulley one more turn to allow the new belt to slip under the tensioner pulley.
    Check the belt for proper alignment on the pulleys. It should lay flat on the pulley and not overhang the edges. If the belt must be repositioned, release the tensioner and reposition as needed.

    you need a belt tensioner tool, release the tension, and remove the old belt (its a tight fit) then re-lace the new belt around the pulleys saving the tensioner pulley for last, retract the tensioner with the tool, and get belt around the pulley. autozone.com has repair guides, and a belt diagram if the sticker is no longer there.

    Serpentine belt broke on 87 ford econo van


    ps...you do not have to Post another Question....just Add a Comment to this question.

    "HOW TO": I professionally prefer the Serpentine Tensioner Tool.
    Standard Rules to Removal the Serpentine Belt with an Automatic Tensioner:
    1. Find the Tensioner(s).
    2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (located on the Tensioner Pulley 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.
    3. Remove the loosened belt off one of the other more easily accessed Pulleys.
    4. 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 an Automatic Tensioner:
    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 and 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.
