DRIVE BELT TENSION CHECK
1. Check that the indicator marking of the auto-tensioner
is within the range as shown in the illustration A of the
tensioner bracket.
Caution
Inspection must be carried out after turning the
crankshaft clockwise for more than once.
2. If the marking is outside the range as shown in the
illustration A, replace the drive belt.
NOTE
Due to the adoption of the auto-tensioner, no adjustment
for belt tension is required.
AUTO-TENSIONER CHECK
1. Check that the driver belt stays within the width of the
pulley of the auto-tensioner after turning off the engine
at idle.
2. Remove the drive belt.(Refer to P.11C-15.)
3. Use the 12.7sq. spinner handle and etc. to check that
the auto-tensioner is not stuck by turning it in both
directions.
4. If there is any abnormality in the above - mentioned 1
or 3, replace the auto-tensioner.
5. Install the drive belt.(Refer to P.11C-15.)

To determine whether the auto-tensioner is acceptable can
be done by checking the drive belt tension.
1. Use the following procedure to check the drive belt tension.

(1) Connect the special tool (MB991668) to the MUT-II.
(2) Connect the MUT-IIto the diagnosis connector.
Caution
Connection and disconnection of the MUT-IImust
be carried out after turning the ignition switch
to the “LOCK” (OFF) position.
(3) Turn the ignition switch to the “ON” position and select
“Belt Tension Measurement” from the menu screen.

(4) Hold the special tool (MB991668) to the middle of
the belt between the pulleys (at the place indicated
by the arrow) about 10 - 20 mm away from the rear
surface and so that it is perpendicular to the belt
(within an angle of±15°).
(5) Gently tap the middle of the belt between the pulleys
(at the place 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.
Standard value: 110 - 144 Hz
Caution
1) Check the vibration frequency of the belt when
the temperature of the surface of the belt is
as close as possible to normal temperature.
2) Do not let any contaminants such as water
or oil get onto the microphone.
3) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
4) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.
5) Do not take the measurement while the
vehicle’s engine is running.

Use the belt tension gauge and check that the belt tension
of the middle of the belt between pulleys
(at the place indicated by arrow) is within the standard
value.
Standard value: 245 - 412 N
2. If the value is outside the standard value, replace the
drive belt.Power steering

AA"DRIVE BELT REMOVAL
Due to the adoption of the Serpentine drive system with the
auto-tensioner, the following operation is required:
1. Insert the 12.7sq. spinner handle and etc. into the tool
hole of the auto-tensioner and rotate it counterclockwise
until the auto-tensioner gets to the stopper.
2. Align hole A with hole B for fixing by inserting the L-shaped
hexagon wrench, then remove the drive belt.
Caution
When the drive belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.
