Timing Belt: Service and Repair

Timing Components:

TIMING BELT REMOVAL

CAUTION:
- Turn the crankshaft pulley so that the No.1 piston is at top dead center (TDC) before removing the timing belt.
- Inspect the water pump before installing the timing belt.

1. Remove the splash shield.
2. Remove the mounting bolts and adjusting bolt, then remove the power steering pump belt and pump.
3. Loosen the idler pulley bracket bolt and adjusting bolt, then remove the air conditioning (A/C) compressor belt.





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





5. Remove the P/S pump lower bracket and heat shield.
6. Remove the cruise control actuator.





7. Remove the side engine mount.

NOTE:
- Use a jack to support the engine before removing the side engine mount.
- Make sure to place a cushion between the oil pan and the jack.

8. Remove the cylinder head cover.
9. Remove the pulley bolt and crankshaft pulley.
10. Remove the middle cover and the lower cover.

NOTE:
- Do not use the middle cover and lower cover to store removed items.
- Clean the middle cover and lower cover before installation.

11. Loosen the adjusting bolt 180°.
12. Push the tensioner to remove tension from the timing belt, then retighten the bolt.
13. Remove the timing belt from the pulleys.

NOTE: Replace the camshaft and crankshaft seals when oil leakage.





TIMING BELT 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 V pointer on the oil pump.

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





3. Install the timing belt tightly in the sequence shown.

(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 five or six turns counterclockwise so that the belt positions itself on the pulleys.
6. Adjust the timing belt tension.

7. Check the crankshaft pulley and the camshaft pulleys at TDC.
8. If either camshaft pulley is not positioned at TDC, remove the timing belt and adjust the positioning of the crankshaft and the camshaft pulleys, then reinstall the timing belt.

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