<2.4L ENGINE> Drive Belt Tension Check and
Adjustment

Check the drive belt tension by the following procedure.
<When using scan tool MB991502>

Required Special Tools:

•

MB991502: Scan Tool (MUT-II)

•

MB991668: Belt Tension Meter Set

Gently tap the middle of the belt between the pulleys (the
location indicated by the arrow) with your finger as shown in the
illustration, and check that the vibration frequency of the belt is
within the standard value range.

NOTE: Refer to

P.00-40

for details on the method of measuring

the vibration frequency using the scan tool.

<When using a tension gauge>
Use a belt tension gauge to check that the belt tension is within
the standard value.
