Drive Belt On-Vehicle Inspection

Check the belt for wear, cracks or other signs of damage.
If any of the following defects is found, replace the V-ribbed belt.

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

Check that the belt fits properly in the ribbed grooves.

HINT:

Check with your 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 the V-ribbed belt deflection and tension.

Standard Deflection:

Item	Specified Condition
New belt	7.0 to 8.2 mm (0.276 to 0.323 in.)
Used belt	7.6 to 10.0 mm (0.299 to 0.394 in.)

Standard Tension:

Item	Specified Condition
New belt	700 to 800 N (70 to 80 kgf, 157.4 to 179.8 lbf)
Used belt	550 to 750 N (55 to 75 kgf, 123.6 to 168.6 lbf)

HINT:

1. When inspecting the V-ribbed belt deflection, apply 98 N (10 kgf, 22.0 lbf) of tensile force to it.
   
2. Check the V-ribbed belt deflection at the specified point.
   
3. V-ribbed belt tension and deflection should be checked after 2 revolutions of engine cranking.
   
4. Measure the belt tension when the engine is cold.
   
5. When adjusting the belt, be sure to adjust it so that the tension is as close as possible to the median of the specified range.
   
6. When replacing the belt with a new one, be sure to perform the following after adjusting the belt: idle the engine for 5 minutes, and then adjust the belt to the specified value for a new belt after the engine has cooled.
   
7. When inspecting a belt which has been used for over 5 minutes, apply the used belt specifications.
   
8. When using a belt tension gauge, confirm its accuracy by using a master gauge first.
