Timing Belt: Service and Repair

TIMING BELT 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 to be reused.

1. Remove the splash shield.





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





3. On vehicles with A/C remove the A/C compressor adjusting pulley with bracket and the belt.
4. Remove the P/S bracket.





5. Loosen the alternator adjusting bolt and pivot nut, then remove the belt.
6. Remove the cruise control actuator.





7. Remove the engine support nuts. Loosen the mount bolt and pivot the side engine mount out of the way.
8. Remove the cylinder head cover.
9. Remove the timing belt upper cover.
10. Remove the special bolt and crankshaft pulley.
11. Remove the timing belt upper cover and the lower cover.
12. Loosen the timing belt adjusting bolt 180°.
13. Push the tensioner to release tension from the belt, then retighten the adjusting bolt.
14. Remove the timing belt from the pulleys.





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). Align the groove on the teeth side of the timing belt drive pulley to the pointer on the oil pump.
B. Align the TDC mark on the camshaft pulley with pointer on the back cover.





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

(1) Timing belt drive pulley (crankshaft) -> (2) Adjusting pulley -> (3) Water pump pulley -> (4) 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 on the pulleys.
6. Adjust the timing belt tension.

Crankshaft Pulley:

Camshaft Pulley:

7. Check the crankshaft pulley and the camshaft pulley at TDC.
8. If the camshaft pulley is not positioned at TDC remove the timing belt and adjust the positioning and repeat the installation procedure and reinstall the timing belt.

After installation, adjust the tension of each belt.
