Car broke down due to fan belt and no tensioner bolt. Is the tensioner connected to the alternator


Yes the belt runs over the alternator, A/C etc. This page shows how it works, and the tensioner needs to keep tension on the belt to drive the pulleys including the alternator.

Trying to remove alternator belt to get the alternator out


It looks like you have one belt for all accessories. There should be a belt tensioner that keeps the belt tight. You move the tensioner to release tension on the belt, then remove the belt from the alternator pulley.

How to replace the power steering belt on a 4g13



ADJUSTMENT

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

I am trying to hange the serpentine belt on my 09 lancer rallyart and it keeps slipping off


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.

      2. Alternator belt (used): 68-86 lbs. (304-383 N)
      3. A/C compressor and power steering pump belt (new): 110-132 lbs (491-589 N)
      4. A/C compressor and power steering pump belt (used): 95-110 lbs. (422-491 N)

        Fig. Using a tension gauge to measure the alternator belt tension - 1.8L engines (click HERE for zoom)


    2. Using the deflection method, apply moderate pressure (about 22 lbs) halfway between the pulleys, and compare with the following specifications.
      1. Alternator belt (new): 0.31-0.35 in. (8-9mm)
      2. Alternator belt (used): 0.35-0.39 in. (9-10mm)
      3. A/C compressor and power steering pump belt (new): 0.31-0.35 in. (8-9mm)
      4. A/C compressor and power steering pump belt (used): 0.35-0.39 in. (9-10mm)
    3. If the specifications fall outside the ranges given, adjust the belt as follows:
      1. Loosen the alternator mounting bolt and adjusting bolt.
      2. Adjust the alternator to get the specified belt deflection.
      3. Tighten the bolts, then recheck the tension.

    2. Adjust the new belt to specifications as follows: Turn the idler pulley nut to the right to tighten the belt to a specification of 220-265 lbs. (980-1180 N). Torque the idler pulley nut to 25-37 ft. lbs. (34-50 Nm).

    POWER STEERING AND AIR CONDITIONING BELT
    See Figure 2
    1. Remove the alternator belt.
    2. Loosen the nut on the tensioner pulley.
    3. Turn the belt adjusting screw on the tensioner counterclockwise until the belt can be removed, then remove the belt.
