| *a | Turn |
Using the crankshaft pulley bolt, align its groove with the timing pointer by turning the crankshaft clockwise.
Check that timing marks of the camshaft timing pulley and No.2 timing belt cover are aligned.
If not, turn the crankshaft 1 revolution (360°).
| *a | Turn |
Turn the crankshaft 90° counterclockwise, and put the timing mark of the crankshaft timing pulley with the protrusion of the timing belt case.
Note
If the timing belt is disengaged, having the crankshaft timing pulley at the wrong angle can cause the piston head and valve head to come into contact with each other when you remove the camshaft timing pulley, causing damage. So always set the crankshaft pulley at the correct angle.
| *a | Move |
