− Drive Belts

(Check Condition)

P.00-41

.

AUTO-TENSIONER CHECK

M1111003000035

1. Run the engine at idling speed and then stop it to check

whether the drive belt is centered on the auto-tensioner
pulley.

2. Insert a1/2 inch breaker bar into the square hole on the drive

belt auto tensioner, and rotate it clockwise until the tensioner
touches the stopper.

3. Align hole B with hole A, and insert a 5.0 mm (0.20 inch)

Allen wrench to hold the tensioner. Then loosen the drive
belt, and then remove the drive belt auto tensioner.

4. Move the auto-tensioner right and left by using a 1/2 inch

breaker bar or similar tool to verify that it moves smoothly.

5. If some abnormality is found during the above mentioned

check (1) and (3), replace the auto-tensioner.

2. Connect scan tool MB991958 to the data link connector.
3. Set up a timing light.
4. Start the engine and run it at idle.
5. Check that the idle speed is approximately 700 r/min.
6. Select scan tool MB991958 actuator test "item number 17".
7. Check that basic ignition timing is within the standard value.

Standard value: 5

° BTDC ± 3°

8. If the basic ignition timing is not within the standard value,

check the following items:

• Diagnostic output

• Timing belt cover and crankshaft position sensor installation

conditions
