The timing belt must be removed on a cold engine!
Do not turn the engine with the timing belt removed!
Removal
1. Disconnect the negative cable from the battery.
2. Remove the air cleaner.
3. Set the parking brake, jack up the front of the car and place it on supports. Remove the right front wheel.
4. Mark the direction of rotation of the accessory drive belt with chalk or paint. Using a spanner, loosen the belt and remove it from the engine (see Chapter Vehicle settings and routine maintenance).
5. Remove the upper section of the timing belt cover (see section Removal and installation the timing belt cover).
6. Set the crankshaft to the TDC position of the first cylinder (see section SOHC Gasoline Engine Repair Procedures Without Removing Them From The Vehicle) and do not change this position.
7. Remove the crankshaft pulley (see section Removal and installation the crankshaft pulley).
8. Remove the lower section of the timing belt cover (see section Removal and installation the timing belt cover).
9. If you plan to install the old timing belt, mark the direction of its movement with a felt-tip pen (clockwise).
10. Loosen the belt tension. To do this, press the tension roller (1) so that the holes in its movable element (3) and in the plate (2) align. Fix the toothed belt tension roller in the resulting position with a suitable rod.

11. Remove the timing belt.
Do not rotate the shafts with the belt removed.
Installation
1. Make sure that the alignment marks are correctly aligned (refer to the illustrations).
2. Starting from the crankshaft gear and moving counterclockwise, install the timing belt according to the routing diagram. Make sure the belt is tensioned in the areas between adjacent wheels.
If you are installing an old belt, pay attention to the direction of its movement.

3. Remove the locking rod from the tensioner and loosen the water pump assembly mounting bolts.
4. Tighten the timing belt by turning the water pump with a tool KM-421-A so that the movable element (1) of the tension roller (2) is opposite the right stop. If the specified tool is not available, a suitable spanner can be used (approximately 42.5 mm).
Adjusting the Timing Belt Tension, Step 1
5. Turn the crankshaft two full turns clockwise and ensure that the TDC timing marks are correctly aligned.
Turn the crankshaft smoothly so as not to disturb the position of the water pump.
6. Slightly tighten the timing belt by turning the water pump counterclockwise until the pointer (1) and the mark on the tension roller plate (2) align.
Adjusting the Timing Belt Tension, Step 2
7. Tighten the pump mounting bolts to the required torque (8 Nm).
8. Screw in all the crankshaft pulley mounting bolts. Remove the locking mandrel and turn the shaft by hand two turns clockwise. Finally, check whether the crankshaft and camshaft pulley marks are opposite each other.
9. Check the tension of the toothed belt: the pointer of the movable element of the tension roller should coincide with the plate. Otherwise, repeat the adjustment.
If it is necessary to loosen the timing belt tension during installation, press the tensioner with your finger so that the holes (3) align.
10. In this position, insert a suitable rod into the holes. This will lock the tensioner and allow the belt to be removed.
11. Reinstall the removed components in the reverse order of removal.
12. When installing the air filter, check and, if necessary, replace its filter element.
13. Screw in the crankshaft pulley bolt and tighten it to the required torque.
14. On engine C14NZ check and adjust ignition if necessary.
