- Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.





- Using several steps, uniformly install and tighten the 10 cylinder head bolts with plate washers with a 10 mm bi-hexagon wrench in the sequence shown in the illustration.
Torque: 39 Nm (398 kgf-cm, 29 ft-lbf)





- Mark the front of the cylinder head bolt head with paint.
- Retighten the cylinder head bolts by 90° in the same order.
- Retighten the cylinder head bolts by an additional 90°.
- Check that the painted mark is at a 180° from the original position.
