Timing Belt Removal and Installation

TIMING BELT INSTALLATION





NOTE: Measure the tensioner spring free length. If not within the specification, replace the tensioner spring.

Free length: 59.2 mm (2.33 in)





1. Install the belt tensioner and tensioner spring.
(1) Protect the tensioner with a rag. Pry the tensioner outward by using a bar.
(2) Temporarily tighten the tensioner lock bolt with the tensioner spring fully extended.

2. Install the timing belt.





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





(2) Verify that the camshaft pulley marks are aligned with the seal plate marks. E for intake side, and I for exhaust side.





(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.
(5) Turn the crankshaft two turns clockwise and face the pin on the pulley boss straight up. Do not turn the crankshaft counterclockwise.
(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 D011 102, loosen the pulley lock bolt and remove the bolt and pulley boss. 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. Be sure not to apply tension other than that of the tensioner spring.
(11) Tighten the tensioner lock bolt.

Tightening torque: 38 - 51 N.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 (22 lbf) midway between the camshaft pulleys. If the deflection is not correct, repeat from step 10 above.

Deflection: 9.0 - 11.5 mm (0.36 - 0.45 in)

3. Install the lower timing belt cover.
4. Install the middle and upper timing belt cover.
5. Install the cylinder head cover.
6. Install the PCV valve.
7. Install the ignition coil and high-tension leads and sparkplugs.
8. Install the pulley lock bolt and pulley boss.





Hold the crankshaft by using the SST 49 D011 102 and tighten the pulley lock bolt.

Tightening torque: 157 - 166 N.m (116 - 122 ft.lbf)

9. Install the crankshaft pulley plate and crankshaft pulley.
10. Install the water pump pulley.
11. Install the generator drive belt.
12. Install the P/S and/or A/C drive belt.
13. Install the water hose (connected to thermostat housing).
14. Install the upper radiator hose.
15. Install the air intake pipe.
16. Install the splash shield.
17. Reconnect the negative battery cable.
18. Fill the radiator with the specified amount and type of engine coolant.
19. Start the engine and
(1) Check the engine coolant leakage.
(2) Check the ignition timing and idle speed.
(3) Check the operation of the emission control system.

20. Recheck the engine coolant level.
