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

Step 1:
- Set the plate washer to the cylinder head bolt.

- Install and uniformly tighten the 10 cylinder head bolts and plate washers in the sequence shown in the illustration.
Torque: 32 Nm (326 kgf-cm, 24 ft-lbf)

If any one of the cylinder head bolts does not meet the torque specification, replace the cylinder head bolt.

HINT: The cylinder head bolts are tightened in 3 progressive steps.

NOTE: Do not drop the plate washer for the cylinder head bolt into portion A of the cylinder head. If dropped into portion A, the plate washer will pass through the cylinder head and cylinder block into the oil pan.

Step 2:

- Mark the cylinder head bolt head with paint as shown in the illustration.
- Tighten the cylinder head bolts another 90° in the sequence shown in step 1.
