Timing Belt: Service and Repair

TIMING BELT

1. Disconnect the negative battery cable.

2. Raise the vehicle on a lift and remove the right front wheel.

REMOVAL

Pulley lock bolt





1. Hold the pulley boss with the SST.

2. Using the SST loosen the pulley lock bolt.

3. Remove the bolt and the pulley boss.

Timing belt

1. Install the pulley boss and pulley lock bolt.





2. Turn the crankshaft to align the timing marks.





NOTE:
^ The pin on the pulley boss must face upward.

CAUTION:
^ After setting the marks, do not turn the crankshaft when removing the pulley lock bolt and pulley boss.





NOTE:
^ Mark the timing belt rotation for proper reinstallation.





CAUTION:
^ Protect the tensioner with a rag before prying on it.

3. Loosen the tensioner lock bolt and, using a suitable bar, pry the tensioner outward (arrow).

4. Tighten the lock bolt with the tensioner spring fully extended.

5. Remove the timing belt.





INSTALLATION

Tensioner and tensioner spring

1. Install the tensioner and the tensioner spring.

CAUTION:
^ Protect the tensioner with a rag before prying on it.





2. Using a suitable bar, pry the tensioner outward (arrow).

3. Temporarily tighten the tensioner lock bolt with the tensioner spring fully extended.

Timing belt






1. Verify that the timing belt pulley mark is aligned with the timing mark.






2. Turn the camshafts until the camshaft dowel pins face straight up.Verify that the camshaft pulley marks are aligned with the seal plate marks.
3. Install the timing belt so that there is no looseness at the idler side or between the camshaft pulleys.

4. Install the pulley boss and pulley lock bolt.

CAUTION:
^ Do not turn the crankshaft counterclockwise.






5. Turn the crankshaft two turns clockwise and face the pin on the pulley boss upright.

6. Verify that the camshaft pulley marks are again aligned with the seal plate marks. If not aligned, remove the timing belt and repeat from tensioner installation.

Fig. 71 Tension Set Mark Alignment:

7. Turn the crankshaft 1 and 5/6 turns clockwise and align the timing belt pulley mark with the tension set mark for proper timing belt tension adjustment.

8. Using the SST (49 D01 1102), loosen the pulley lock bolt and remove the bolt and pulley boss.

CAUTION:
^ Do not turn the crankshaft.

9. Verify that the timing belt pulley mark is aligned with the tension set mark.






10. Loosen the tensioner lock bolt to apply spring tension to the timing belt.

11. Tighten the tensioner lock bolt.

Tightening torque:
38-51 N-m (3.8-5.3 kgf-m, 28-38 ft-lbf)

12. Install the pulley boss and pulley lock bolt.

13. Turn the crankshaft 2 and 1/6 turns clockwise and verify that the timing marks are correctly aligned.






14. Measure the timing belt deflection by applying moderate pressure 98 N (10 kgf, 22 lbf) midway between the camshaft pulleys. If the deflection is not correct. repeat from Step 10 above.

Deflection:
9.0-11.5mm (0.35-0.45 in at 98 N 10 kgf, 22 lbf)






Spark plug
Install the spark plugs.

Tightening torque:
15-22 N-m (1.5-2.3 kgf-m, 11-16 ft-lbf)






Pulley lock bolt
Hold the crankshaft with the SST and tighten the pulley lock bolt.

Tightening torque:
157-166 N-m (16-17 kgf-m, 116-122 ft-lbf)

Steps After Installation

1. Connect the negative battery cable.

2. Start the engine and check the Ignition timing.
