On-Vehicle Inspection


    Object Number: 2016702  Size: SH
  1. Inspect the V-ribbed belt for wear, cracks or other signs of damage.
  2. If any of the following defects is found, replace the V-ribbed belt.

    • The belt is cracked.
    • The belt is worn out to the extent that wires are exposed.
    • The belt has chunks missing from the ribbed grooves.

    Object Number: 2016704  Size: SH

    Note: Check by hand to confirm that the belt has not slipped out of the grooves on the bottom to the pulley. If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt correctly.

  3. Check that the belt fits properly in the ribbed grooves.

  4. Object Number: 2016705  Size: SH
  5. On vehicles equipped with air conditioning, check the belt deflection and tension in positions shown (1, 2).

  6. Object Number: 2016707  Size: SH
  7. On vehicles without air conditioning, check the belt deflection and tension in position shown (1).
  8. If the belt deflection is not as specified, adjust it. Refer to Engine Mechanical Specifications.
  9. • When inspecting the belt deflection, apply 98 N (10 kgf) tensile force to it.
    • After installing a new belt, run the engine for approximately 5 minutes and then re-adjust the tension to (new belt) specifications.
    • Check the V-ribbed belt deflection and tension at the specified point.
    • V-ribbed belt tension and deflection should be checked after 2 revolutions of the engine.
    • V-ribbed belt tension and deflection should be checked at TDC crank angle and cold condition.
    • When adjusting a belt, adjust its deflection and tension to the intermediate values of the specification.
    • When reinstalling a belt which has been used for over 5 minutes, adjust its deflection and tension to the used belt specification.
    • When using a belt tension gauge, confirm its accuracy by using a master gauge first.
    • If using a sonic tension meter: Input data for sonic tension meter.
