On-Vehicle Inspection
- Inspect the V-ribbed belt for wear, cracks or other signs of damage.
If any of the following defects is found, replace
the V-ribbed belt.
• | The belt is worn out to the extent that wires are exposed. |
• | The belt has chunks missing from the ribbed grooves. |
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.
- Check that the belt fits properly in the ribbed grooves.
- On vehicles equipped with air conditioning, check the belt deflection and tension in positions shown (1, 2).
- On vehicles without air conditioning, check the belt deflection and tension in position shown (1).
- If the belt deflection is not as specified, adjust it. Refer to
Engine Mechanical Specifications.
• | 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. |
Specification
• | Span: 188 mm (7.40 in) (w/A/C) |
• | Span: 282 mm (11.1 in) (without A/C) |
