DRIVE BELT

Structure
• The drive belt is a serpentine type, which uses a V-ribbed belt to drive the supplemental units. This shortens
the length of engine and makes it easier to service.
• The front drive belt's auto tensioner, in which the coil spring is embedded, has been adopted for the drive belt's
tension. The tensioner pulley automatically maintains the drive belt's tension.
