Checking Drive BeltsNBS0000D
WARNING:
Be sure to perform this step when engine is stopped.

Make sure that the indicator (C) (notch on fixed side) of drive belt auto-tensioner is within the possible use
range (A).
NOTE:
Check the drive belt auto-tensioner indication when the engine is cold.

When new drive belt is installed, the indicator (C) (notch on fixed side) should be within the range (B) in
the figure.

Visually check entire drive belt for wear, damage or cracks.

If the indicator (C) (notch on fixed side) is out of the possible use range or belts is damaged, replace drive
belt.
Tension AdjustmentNBS0000E
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
