DRIVE BELT TENSION CHECK

M1111003102254

1. Remove the radiator condenser tank. (Refer to GROUP 14,

Radiator

P.14-31

CAUTION

Check the drive belt tension after turning the crankshaft
clockwise one turn or more.
2. Make sure that the indicator mark on the auto-tensioner is

within the area marked with A in the illustration.

3. If the mark is out of the area A, replace the drive belt (Refer

P.11A-21

NOTE: The drive belt tension check is not necessary as the
auto-tensioner is adopted.

4. Install the radiator condenser tank. (Refer to GROUP 14,

Radiator

P.14-31

AUTO-TENSIONER CHECK

M1111003001384

OPERATION CHECK

1. Stop the engine from the idle state.
2. Remove the radiator condenser tank. (Refer to GROUP 14,

Radiator

P.14-31

3. Check that the drive belt is not protruding from the pulley

width of the auto-tensioner.

4. Remove the drive belt (Refer to

P.11A-21

5. Rotate the pulley bolt of the auto-tensioner clockwise and

counterclockwise with an offset wrench [45

° , a long offset

wrench (5/8 x 11/16 inches) recommended] to check for
binding.

6. If there are any problems in the procedure 3 or 5, replace

the auto-tensioner. (Refer to

P.11A-69

7. Install the drive belt. (Refer to

P.11A-21

8. Install the radiator condenser tank. (Refer to GROUP 14,

Radiator

P.14-31

FUNCTION CHECK

The auto-tensioner can be checked whether it is in good condi-
tion by checking its tension.

Required Special Tools:

• MB992080: Belt Tension Meter Set

• MB992081: Belt Tension Meter

• MB992082: Mic Assembly

1. Check the tension of the drive belt. (Refer to

2. Check the tension of the drive belt in the following

procedures.

(1) Connect special tool microphone assembly (MB992082)

to special tool belt tension meter (MB992081) of special
tool belt tension meter set (MB992080).

(2) Press the "POWER" button to turn on the power supply.
(3) Press the numeral key of "1" and check that "No. 1"

appears on the upper left of the display.
NOTE: This operation is to temporarily set the preset
data such as the belt specifications, because if the mea-
surement is taken without input of the belt specifications,
conversion to tension value (N) cannot be made, result-
ing in judgement of error.

(4) Press "Hz" button twice to change the display to the

frequency display (Hz).

CAUTION

• The temperature of the surface of the belt should be as

close to normal temperature as possible.

• Do not allow any contaminants such as water or oil to

get onto the microphone.

• If strong gusts of wind blow against the microphone or

if there are any loud sources of noise nearby, the val-
ues measured by the microphone may not correspond
to actual values.

• If the microphone is touching the belt while the mea-

surement is being made, the values measured by the
microphone may not correspond to actual values.

• Do not take the measurement while the vehicle's engine

is running.

(5) Hold special tool MB992080 to the middle of the belt

between the pulleys (at the place indicated by arrow)
where it does not contact the belt (approximately 10

− 15

mm (0.4

− 0.59 inch) away from the rear surface of the

belt) so that it is perpendicular to the belt (within an angle
of

± 15 degree).

(6) Press the "MEASURE" button.
(7) Gently tap the middle of the belt between the pulleys (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: 98

− 124 Hz

NOTE: To take the measurement repeatedly, tap the belt
again.

(8) Press and hold the "POWER" button to turn off the power

supply.

3. If not within the standard value, replace the auto-tensioner.

<When using a tension gauge>

1. Check the tension of the drive belt. (Refer to

P.11A-8

2. Use a belt tension gauge in the middle of the belt between

the pulleys shown in the figure (at the place indicated by the
arrow) to check that the belt tension is within the standard
value.

Standard value: 248

− 400 N (56 − 90 lb)

3. If not within the standard value, replace the auto-tensioner.

IGNITION TIMING CHECK

M1111001702216

Required Special Tool:
MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

1. Before inspection, set the vehicle in the following condition:

• Engine coolant temperature: 80 − 95° C (176 − 203° F)

• Lights and all accessories: OFF

• Transaxle: Neutral (P range on vehicles with TC-SST)

NOTE: On vehicles for Canada, the headlight, taillight, etc.
remain lit even when the lighting switch is in "OFF" position
but this is no problem for checks.
