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 groove on the bottom of the pulley.

If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt.

Using a belt tension gauge, inspect the belt tension.

Standard Belt Tension:

Item	Condition	Specified Condition
New belt	5 to 35°C (41 to 95°F)	550 to 800 N (56 to 82 kgf, 123.6 to 179.8 lbf)
Used belt	5 to 35°C (41 to 95°F)	300 to 500 N (31 to 51 kgf, 67.4 to 112.4 lbf)

HINT:

1. When measuring the tension of a new belt, measure the tension immediately after installing it to the engine but before starting the engine.
   
2. A "new belt" is a belt which has been used for less than 5 minutes on a running engine.
   
3. A "used belt" is a belt which has been used on a running engine for 5 minutes or more.
   
4. After installing a new belt, run the engine for approximately 5 minutes and then recheck the tension.
   

Check that nothing gets caught in the tensioner by turning it clockwise and counterclockwise.
If a malfunction exists, replace the tensioner.
