2. Remove the generator.
a) Disconnect the wire harness clamp from the clamp on the generator.
b) Disconnect the generator connector.
c) Remove the rubber cap and unscrew the wire fastening nut, and disconnect the generator wire.
d) Loosen the lock bolt (models with air conditioning), adjusting bolt and hinge bolt.
d) Remove the generator drive belt.
e) Remove the adjustment lock bolt (models with air conditioning) or adjusting bolt (models without air conditioning) and a hinge bolt.
g) Remove the generator.
3. Remove the spark plugs.
a) Disconnect the high-voltage wires by the rubber caps. Do not pull the high-voltage wires.
b) Remove the spark plugs.
4. Remove the upper timing belt cover by removing five bolts and two gaskets.
5. Set the piston of cylinder No.1 to TDC of the compression stroke.
a) Turn the crankshaft pulley and align its mark with the "O" timing mark on the lower timing belt cover.
b) Check that the timing notch on the camshaft sprocket is aligned with the timing mark on the bearing cap. If not, turn the crankshaft one revolution (360°).
6. Remove the timing belt from the camshaft sprocket.
Note: When reusing the timing belt, apply an arrow in the direction of rotation, marks on the timing belt and camshaft sprocket, and align them with the mark on the lower timing belt cover as shown in the figure.
a) Loosen the tension roller mounting bolt and, being careful not to damage the belt, push the roller to the left as far as possible and temporarily tighten the bolt.
b) Remove the timing belt from the camshaft toothed pulley.
Parts for removal and installation (3S-FE, 4S-FE).
1 - crankshaft pulley,
2 - lower timing belt cover,
3 - gasket,
4 - right engine mount support,
5 - upper timing belt cover,
6 - timing belt,
7 - wire to the generator,
8 - generator connector,

12 - high-voltage wires,
13 - spark plug,
14 - tension roller spring,
15 - crankshaft toothed pulley,
16 - toothed pulley of the oil pump,
17 - intermediate roller,
18 - tension roller,
19 - camshaft toothed pulley,
20 - wiring harness protection.
7. If necessary, remove the camshaft toothed pulley by unscrewing the mounting bolt.
8. Remove the crankshaft pulley.
a) Using a special tool, loosen the pulley bolt.
Note:
- When reusing the timing belt, after loosening the crankshaft pulley bolt, check that the timing belt and timing belt lower cover marks are aligned by aligning the timing marks (the notch on the crankshaft pulley and the "O" on the timing belt lower cover).
- When the bolt is loosened, the crankshaft may turn and since it is not synchronized with the camshaft, the valves may collide with the piston.
b) Remove the timing belt from the camshaft toothed pulley.
If the marks are not aligned, then do the following:
Note:
- The crankshaft can only be turned clockwise.
- Align the alignment marks as shown in the figure.
After aligning the marks, hold the timing belt and turn the crankshaft pulley, aligning its installation mark with the installation mark "0" on the lower timing belt cover
b) Remove the pulley using a puller.
9. Remove the lower timing belt cover by unscrewing the four bolts and remove the gasket.
10. Remove the timing belt guide.
11. Remove the timing belt.
Note: When reusing the timing belt, mark it with an arrow in the direction of rotation and make marks on the timing belt and crankshaft sprocket.
12. Remove the tension roller and tension roller spring by unscrewing the bolt.
13. If necessary, remove the intermediate pulley by unscrewing the bolt.
14. If necessary, remove the crankshaft timing pulley. If the pulley is difficult to remove by hand, use two screwdrivers.
Note: Place the rag as shown in the picture to prevent damage.
15. If necessary, remove the oil pump pulley by unscrewing the nut.
