Serpentine belt too tight to install

I'm attempting to replace the serpentine belt on my 2000 Isuzu Trooper, and even after loosening the tensioner, it is way too tight to install. I've confirmed that it is the right belt. Should I attempt to loosen the entire tensioner assembly, or attempt to pry the belt over the idler pulley to complete the install?

I had the same problem when trying to replace the serpentine belt on my 2001 Trooper. The Maintenance book was very vague and I couldn't tell exactly how the tension was taken off the belt, but it did clearly identify the tensioner pulley. I first removed the pulley and looked for some kind of slot that would give me the adjustment I needed, but no slotted adjustment is present on the 01 Trooper. I had to do some research so I pulled of the tensioner assembly and found that there is a spring coil which keeps tension on the belt constant, and eliminates any belt alignment problems.

The Litens style tensioner uses a spring to apply pressure towards the serpentine belt. The way to relax the spring is to use your 14mm socket and ratchet and force the pulley down by driving the pulley nut in the clockwise direction. This forces the spring to compress and the pulley to drop giving the needed clearance to get your new belt in place.

Make sure you have loosened the tension bolt ENTIRELY. They can go REALLY loose so you can easily install the belt. You should be able to see how much more you can loosen it by looking at the backside of the bolt. If you were to remove the pulley and the same tension is on the belt, you will have the same trouble getting your tensionor back on and you risk stripping the threads by tightening the bolt at an indirect angle.

Squeeling when starting.lasts about 30 sec.has 2 belts 1 small w/tensioner,1 lg serpentine can't find tensioner for it. where is it ?


Sounds like your serpentine belt has become stretched over time and needs to be replaced. One of the pulleys is going to be spring loaded and placing a wrench on it and pushing or pulling(gently but firmly) will give you the direction to loosen it off. This belt tensioner is non adjustable .It either tightens the belt enough or it doesn't hence the squeal.Good luck.

Replace alternator belt


  • Locate the two belts on the left side (passenger side) of your Mitsubishi Lancer. The outer belt is a serpentine belt, operating four pulleys and the inner belt is your alternator belt.

  • 2

    Follow the serpentine (outer) belt to the three pulleys lined up vertically near the front of the engine compartment. Locate the middle pulley, which is the tension pulley for the belt.

  • 3

    Loosen the bolt on the middle pulley with a socket wrench by turning counter-clockwise. Do not remove the bolt, just turn it a couple of times. Loosen the tensioner bolt on the side of the of the pulley, facing the front of the vehicle.

  • 4

    Remove the serpentine belt and then loosen the bolt on the alternator. With the alternator loose, move it forward so that the alternator belt loosens up and then remove belt from the pulleys.

  • 5

    Install the new alternator belt by placing it over both inside pulleys. Tighten the tension on the alternator belt by moving the alternator back and keeping tension on it by holding it back with a long screwdriver. While the alternator belt is tight, use a socket wrench to tighten up the bolt on the alternator.

  • 6

    Place the serpentine belt back on the pulleys and then use a socket wrench on the bolt on the front of the tension pulley. Once the serpentine belt is tight, tighten up the bolt in the middle of the tension pulley.

  • 7

    Start the Mitsubishi Lancer's engine to test the alternator belt and make sure it is working properly. Once you have verified it is working, turn the engine off.

    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.

    I'm attempting to replace the serpentine belt on my 2000 Isuzu Trooper, but am not able to create enough slack in the belt by loosing the tensioner to slip belt on. I don't want to pry the belt on. Any...


    tensioner usually has a bolt in the center of the pulley wheel that is 17 to 19mm. use a breaker bar and socket to hold pulley back (sometimes has a lock that you can engage) then you can move the belt into and out of the pulleys.
    have the new belt ready after you pull the old one, put it around all BUT the tensioner pulley and it will be MUCH easier to put on if you are by yourself>

    Serpentine belt replacement


    What engine do you have? The 3.3 and 3.8 engines have a single serpentine belt, and a belt tensioner, so no adjustment is needed. Did you replace the tensioner, and want to know how much to torque it? countrycurt0
