NM Pajero 6G7 engine auto tensioner removal

I have an NM Pajero with 6G7 engine which has a serpentine belt and auto tensioner. The auto tensioner is making a clicking noise so I want to remove, inspect and maybe replace. The Mitsubishi Manual on p 11A-17 provides the removal procedure, ie rotate tensioner, lock with allen key, loosen belt, remove tensioner. I am concerned that the tensioner is under spring tension and wonder if this is the correct procedure? Also, what about installation?

    Thanks but when you lock the tensioner with the allen key, it takes the tension off the belt but the tensioner is under more tension than when in its normal position due to its internal spring mechanism.

You'll need to remove/loosen one of the components (such as the alternator or power steering pump) to relieve tension on the belt before removing the tensioner as it should be spring loaded. Installation is going to be the reverse of the removal procedure.
Also, if the tensioner is noisy, replace it.

    Yes therefore the necessity to loosen other components operated by that belt to relieve the remaining tension?

Fig. Accessory serpentine belt (A) routing-3.8L engine


Inspection

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.


Removal & Installation

  1. Disconnect the negative battery cable.
  2. Rotate the auto tensioner clockwise to release tension, then remove the drive belt.

To install:
  1. Install drive belt (A). Route the belt over the components in the following order: Crankshaft pulley - A/C pulley - idler pulley - generator pulley - water pump pulley - P/S pump pulley - tensioner pulley.
  2. Rotate auto tensioner arm in the counter-clockwise moving auto tensioner pulley bolt with wrench.
  3. After putting belt on auto tensioner pulley, release the auto tensioner pulley slowly.

Need to replace Serpentine belt and p/s belt on my 2002 honda odyssey is this complicated?


the procedure is as follows:-- You have to do it from underneath the vehicle. Take off the rivets to the two plastic covers, and then you will be able to see the tensioner for the belt. Use a 3/4 inch wrench on the tensioner (don't put it on the bolt that holds the tensioner on), and pull it toward the vehicle. The belt will loosen, and you can take it off. As a car owner, you know how important the belt tensioner is for your 2002 Honda Odyssey. However, internal parts wear and damage will loosen or seize the tensioner wheel, causing the belt to slip and make noise. Eventually, the belt may break, shut down the engine and lead you into a serious traffic accident. Before that happens, replace the tensioner on your Honda model and save yourself a lot of problems:---- Remove the Drive Belt:-- 1)Look for the drive belt routing diagram on your vehicle's engine compartment. This is a black and white label, about 4 by 6 inches, usually attached to the radiator shroud or near the strut towers inside the engine compartment. This diagram will be your guide when reinstalling the drive belt. If cannot find one, make a simple sketch on a piece of paper. 2) Insert a belt-tension release tool, or similar tool, into the auto-tensioner arm. 3)Rotate the auto-tensioner arm counterclockwise and slip the belt off the tensioner pulley. 4) Release the auto-tensioner but do not let it snap back in place. 5) Remove the drive belt from the engine compartment. Replace the Belt Tensioner 1) Unscrew the two auto-tensioner mounting bolts using a ratchet, ratchet extension and socket. Note the location of each bolt because they are of different size. 2) Remove the old auto-tensioner from the engine compartment. 3) Set the new auto-tensioner in place and start the two mounting bolts by hand. Make sure you install the bolts in their original place. 4) Start tightening the bolts until they hit the stop using the ratchet, ratchet extension and socket. 5) Torque the two bolts using a torque wrench. Torque the small bolt to 16-foot pounds [22 Nm] and the large bolt to 47-foot pounds [64 Nm]. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

(2.2L Engine)
  1. Disconnect the negative battery cable.
  2. Raise and support the front of the vehicle, then remove the passenger side tire and wheel assembly for access to the rear of the alternator through the wheel well.
  3. Working through the wheel well, unfasten the alternator brace-to-block bolt, then remove the brace-to-intake nut and the brace-to-engine stud nut.
  4. Unplug the alternator wiring connector, then remove the battery terminal nut and wire.
  5. Carefully release the serpentine belt tension and remove the belt from the alternator pulley. Do not allow the tensioner to snap back into position once the belt is off the pulley.
  6. Loosen the alternator retaining bolts, then support the alternator and remove the fasteners. Remove the alternator from the vehicle.

To install:
  1. Position the alternator in the vehicle and loosely install the retaining bolts.
  2. On 1994-98 models, tighten the top alternator bolt to 22 ft. lbs. (30 Nm) and the bottom bolt to 32 ft. lbs. (43 Nm).
  3. On 1999-99 models, tighten the rear bolt to 37 ft. lbs. (50 Nm) and the front bolt to 18 ft. lbs. (25 Nm).
  4. On 1994-98 models, install the alternator brace, then tighten the retaining nut(s) and bolts to 22 ft. lbs. (30 Nm).
  5. On 1999-99 models, install the alternator brace, tighten the brace-to-alternator and brace-to-intake retainers to 18 ft. lbs. (25 Nm). Tighten the brace-to-engine stud nut to 37 ft. lbs. (50 Nm).
  6. Install the battery terminal wire and tighten the retaining nut, then engage the alternator wiring connector.
  7. Hold the serpentine drive belt tensioner, back off the belt while slipping the belt over the alternator pulley. Gradually lower the tensioner into contact with the belt, then check for proper alignment and tension.
  8. Connect the negative battery cable.

  6. Disconnect the battery terminal boot wiring from the back of the alternator, then unplug the regulator wiring connector.
  7. Support the alternator and remove the mounting bolts (usually 2) from either side of the alternator, then remove the alternator from the vehicle.
To install:
  1. Position the alternator in the vehicle and loosely install using the mounting bolts.
  2. If equipped, loosely install the brace to the engine and/or alternator.
  3. Tighten the left or front alternator retaining bolts to 36 ft. lbs. (50 Nm), the right or rear alternator bolt to 18 ft. lbs. (25 Nm), the brace bolt to 18 ft. lbs. (25 Nm) and/or the brace nut to 22 ft. lbs. (30 Nm), as applicable.
  4. Connect and secure the alternator wiring.
  5. Carefully relieve the serpentine drive belt tension and position the belt over the alternator pulley, then slowly release the tensioner into position.
  6. If equipped, install the air inlet duct assembly.
  7. Connect the negative battery cable.
