  1. Install the wire harness to terminal B with the nut.

    Torque:
    9.8 N*m{100 kgf*cm, 87 in.*lbf}
  1. Install the terminal cap.



2. INSTALL FAN AND GENERATOR V BELT
  1. Provisionally install the fan and generator V belt onto each pulley.

    NOTICE:
    1. Make sure that there is no foreign matter or liquid, such as oil, on the belt and pulleys.
    2. Make sure that the V belt is securely fitted into the rib grooves of the pulley.


3. ADJUST FAN AND GENERATOR V BELT


    Yaris. Ncp93, 131.1Nz-Fe Battery Charging.Charging System (For Sedan).Generator (For Hatchback)  Installation
  1. Insert an adjusting bar between the engine mounting bracket and generator assembly. Pull the adjusting bar toward the vehicle front to adjust the generator V belt tension.

  1. First tighten bolt A, then tighten bolt B.

    Torque:
    19 N*m{189 kgf*cm, 14 ft.*lbf} for bolt A
    54 N*m{551 kgf*cm, 40 ft.*lbf} for bolt B


4. INSPECT FAN AND GENERATOR V BELT


Yaris. Ncp93, 131
  1. Check the fan and generator V belt for wear, cracks or other signs of damage.
    If any of the following defects is found, replace the fan and generator V belt.

    1. The fan and generator V belt is cracked.
    2. The fan and generator V belt is worn out to the extent that the cords are exposed.
    3. The fan and generator V belt has chunks missing from the ribs.

    HINT:
    Check with your hand to confirm that the fan and generator V belt has not slipped out of the grooves on the bottom of the pulley. If it has slipped out, replace the fan and generator V belt. Install a new fan and generator V belt correctly.

    Deflection:
    Item
    Specified Condition
    New belt
    8.0 to 9.0 mm (0.31 to 0.35 in)
    Used belt
    12.5 to 13.5 mm (0.49 to 0.53 in)
    Tension:
    Item
    Specified Condition
    New belt
    700 to 800 N (71 to 82 kg, 157 to 180 lb)
    Used belt
    300 to 400 N (31 to 41 kg, 67 to 90 lb)
    If the V belt deflection is not as specified, adjust it.
    HINT:
    1. When inspecting the V belt deflection, apply 98 N (10 kgf) tensile force to it.
    2. Perform the V belt inspection and adjustment while the engine is cold.
    3. V-ribbed belt tension and deflection should be checked immediately after installation of a new belt, and after cranking the engine when inspecting a used belt.
    4. Check the V belt deflection at the point between the specified pulleys where the deflection is greatest.
    5. When installing a new belt, set its tension to the intermediate value of the specification.
    6. When inspecting a belt which has been used for over 5 minutes, apply the Used Belt specifications.
    7. When reinstalling a belt which has been used for over 5 minutes, adjust its deflection and tension to the intermediate values of each Used Belt specification.
    8. V-ribbed belt tension and deflection should be checked after 2 revolutions of engine cranking.
    9. When using a belt tension gauge, confirm its accuracy by using a master gauge first.


5. INSTALL NO. 2 CYLINDER HEAD COVER
