14.Check to see whether the metal wire inserted when the
auto-tensioner was installed can be removed without any
resistance.
If the metal wire can be removed without any resistance, it
means that the belt has a proper tension. Therefore, remove
the metal wire. In this condition, check that the rod
protrusion of the auto-tensioner is within the standard value.
Standard value: 4.8
− 6.0 mm (0.19 − 0.24 inch)
15.If the metal wire offers resistance when removed, repeat the
previous steps 10 through 13 until proper belt tension is
obtained.
