Component Tightening Specifications and Sequences
Cylinder HeadCYLINDER HEAD SUB-ASSEMBLY RH (for Bank 1)
Step 1:
Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 8 cylinder head bolts with the plate washers in several steps in the sequence shown in the illustration.
Torque 36 N*m (367 kgf*cm, 27 ft.*lbf)
If any one of the cylinder head bolts does not meet the torque specification, replace the cylinder head bolt.
