INSTRUCTION

ALTERNATOR BELT INSPECTION AND ADJUSTMENT (GASOLINE 2.0)

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 values for the used belt after running engine for five minutes.

Deflection method
Apply a force of 98N (10 kgf, 22 lbf), and measure the deflection between the alternator and crankshaft pulley.

Deflection

• Used Belt: 5.0 ~ 6.0 mm (0.20 ~ 0.23 in)
• New Belt: 4.0 ~ 5.0 mm (0.16 ~ 0.20 in)

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