TIMING BELT

TSB Revision

ENGINE MECHANICAL <3.8L ENGINE>

11A-50

CAUTION

When tightening the center bolt, be careful that the ten-
sioner pulley does not turn with the bolt.
6. Loosen the center bolt of the tensioner pulley. Use special

tool MD998767 and a torque wrench to apply the tension
torque to the timing belt as shown in the illustration. Then
tighten the center bolt to the specified torque.

Standard value: 4.4 N

⋅m (39 in-lb) <Timing belt ten-

sion torque>

Tightening torque: 48

± 6 N⋅m (36 ± 4 ft-lb)

7. Remove the setting pin that has been inserted into the

auto-tensioner.

8. Turn the crankshaft clockwise twice to align the timing

marks.

9. Wait for at least five minutes, then check that the

auto-tensioner pushrod extends within the standard value
range.

Standard value (A): 4.8

− 6.0 mm (0.19 − 0.24 inch)

10.If not, repeat the operation in steps 1 to 8 above.

11.Check again that the timing marks of the sprockets are

aligned.

AUTO-TENSIONER ADJUSTER CHECK

1. Check for oil leak from seal, and replace it if leak is detected.

2. Check for wear or damage at the top of the rod. Replace it, if

required.

3. While holding the auto-tensioner with your hand, press the

end of the pushrod against a metal surface (such as the
cylinder block) with a force of 98

− 196 N (22 − 44 pound)

and measure how far the pushrod is pushed in.

Standard value: Within 1 mm (0.04 inch)
A: Length when no force is applied
B: Length when force is applied
A

− B: Movement in

4. If the measured value is out of the standard value, replace

the auto-tensioner adjuster.
