Purpose, Function
The drive belt transmits rotation force of the crankshaft pulley to the pulley for the auxiliary parts.
Construction
The drive belt is installed to the front of the engine.

A V-ribbed belt has been adopted for the drive belt.
The water pump drive belt is a stretch type.
Drive belt vibration is suppressed by shortening the distance between each pulley.
With the adoption of the oil pressure type drive belt auto tensioner, the change in tension by the oil pressure damper operation is absorbed. As a result, the sliding resistance has been reduced by lowering the drive belt tension setting.
