      Check 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 V-ribbed belt is cracked.

      • The V-ribbed belt is worn out to the extent that the cords are exposed.

      • The V-ribbed belt has chunks missing from the ribs.

   2. Check that the V-ribbed belt fits properly in the ribbed grooves.

      Tech Tips

      Check with your hand to confirm that the V-ribbed 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.

      *a	Measuring Point

      Using a belt tension gauge, inspect the belt tension.

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

      Tech Tips

      
      

      • When measuring the tension of a new V-ribbed belt, measure the tension immediately after installing it to the engine but before starting the engine.

      • A "new V-ribbed belt" is a V-ribbed belt which has been used for less than 5 minutes on a running engine.

      • A "used V-ribbed belt" is a V-ribbed belt which has been used on a running engine for 5 minutes or more.

      • After installing a new V-ribbed belt, run the engine for approximately 5 minutes and then recheck the tension.

3. INSPECT V-RIBBED BELT TENSIONER ASSEMBLY

   
   

   1. 

      Check that nothing gets caught in the V-ribbed belt tensioner assembly by turning it clockwise and counterclockwise.

      If a malfunction exists, replace the V-ribbed belt tensioner assembly.
