Timing Belt: Service and Repair

Timing Components:

REMOVAL

CAUTION:
^ Inspect the water pump when replacing the timing belt.

NOTE:
^ Turn the crankshaft so that No.1 piston is at top dead center.
^ Before removing the timing belt, mark its direction of rotation if it is to be reused.

1. Remove the splash shield.





2. Remove the power steering pump.
^ Do not disconnect the P/S hoses.

3. Loosen the adjusting bolt and idler pulley bracket bolt, then remove the A/C compressor belt.





4. Loosen the alternator adjusting bolt and mounting nut, then remove the alternator belt.





5. Remove the P/S lower bracket and heat shield.

6. Remove the cruise control actuator and the P/S tank bracket.





7. Remove the engine support nuts. Loosen the mount bolt and pivot the engine side mount out of the way.





8. Remove the cylinder head cover.

9. Remove the special bolt and crankshaft pulley.

10. Remove the timing belt middle cover and the lower cover.

11. Loosen the timing belt adjusting bolt 180°.

12. Push the tensioner to release tension from the belt, then retighten the adjusting bolt.

13. Remove the timing belt from the pulleys.





INSTALLATION

1. Install the timing belt in the reverse order of removal, Only key points are described here.

2. Position the crankshaft and the camshaft pulleys as shown before installing the timing belt.

A. Set the crankshaft so that the No.1 piston is at top dead center (TDC).

NOTE:
^ Align the groove on the teeth side of the timing belt drive pulley to the pointer on the oil pump.


B. Align the TDC marks on the intake and exhaust pulleys.





3. Install the timing belt tightly in this sequence, 1) Timing belt drive pulley (crankshaft) 2) Adjusting pulley 3) Water pump pulley 4) Exhaust camshaft pulley 5) Intake camshaft pulley.

4. Loosen the adjusting bolt, and retighten it after tensioning the belt.

5. Rotate the crankshaft about 4 or 6 turns counterclockwise so that the belt positions itself on the pulleys.

6. Adjust the timing belt tension.





7. Check the crankshaft pulley and the cam pulley at TDC.





8. If the camshaft pulley is not positioned at TDC, remove the timing belt and adjust the positioning, then reinstall the timing belt.


NOTE:
^ After installation, adjust the tension of each accessory drive belt.
