26. Rotate the camshaft (1) to the position as shown in the graphic.
27. If the markings from crankshaft and camshaft not align remove the EN-48245 locking tool turn the crankshaft 360° and install EN-48245 locking tool . Refer to step 11.



28. Install the EN-48246 locking tool  (1) to fix the camshaft and install the 4  bolts (2) and tighten to  12 N·m (107 ft in).



29. Loosen the timing belt tensioner bolt (2).
30. Turn the timing belt tensioner with an hex-key (1)  clockwise until the timing belt is solved.



31. Remove the timing belt (1).

1. Rotate the fuel pump drive sprocket that the marks (1) and (2) align.




Note: Examine the correct traveling direction of the timing belt.

Note: Examine that the timing belt is tensioned during the installation.

2. Install the timing belt (1) in the following order:

2.1.	Crankshaft sprocket (7)

2.2.	Water pump pulley (6)

2.3.	Fuel pump drive pulley (4)

2.4.	Timing belt idler pulley (3)

2.5.	Camshaft drive sprocket (2)

2.6.	Timing belt tensioner (5)




3. Turn the hex-key (1) tab in a counterclockwise direction to tension the belt. Turn until the point aligns with the notch (2).

Caution: Refer to Fastener Caution in the Preface section.
