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 (P/S) pump belt and pump.
- Do not disconnect the P/S hoses.
3. Loosen the idler pulley center nut 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 bracket.
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 dipstick, then remove the upper cover.
NOTE: Do not use the upper cover to store removed items.
10. Remove the idler pulley bracket and dipstick pipe.
11. Remove the crankshaft pulley.
12. Remove the lower cover.
NOTE: Do not use the lower cover to store removed items.
13. Remove the crankshaft speed fluctuation (CKF) sensor from the oil pump.
14. Loosen the adjusting bolt 180°.
15. Push the tensioner to release tension from the belt, then retighten the adjusting bolt.
16. Remove the timing belt.
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 marks on the camshaft pulley with pointers 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 five or six turns counterclockwise so that the belt positions on the pulleys.
6. Adjust the timing belt tension.
Adjustments
Camshaft Pulley:
Crankshaft Pulley:
7. Check that 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 following steps 2 and 3, and reinstall the timing belt.
NOTE: After installation, adjust the tension of each drive belt.
