Alternator Drive Belt

ALTERNATOR BELT INSPECTION




NOTE: When using a new belt, first adjust the deflection or tension to the values for the new belt, then readjust the deflection or tension to the value for the used belt after running engine for five minutes.

Deflection method:
Apply a force of 98N (10kg, 22lb), and measure the deflection between the alternator and the water pump pulley.

Deflection
Used belt: 8.5 - 11.5 mm (0.3346 - 0.4528 in)
New belt: 5.5 - 8.0 mm (0.2165 - 0.3150 in)






NOTE: If the belt is worn or damaged, replace it.

Belt tension gauge method: Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions.

Tension
Used belt: 343.2 - 490.3N (35 - 50kg, 77.2 - 110.2lb)
New belt: 686.5 - 882.5N (70 - 90kg, 154.3 - 198.4lb)

NOTE: If the belt is worn or damaged, replace it.
