Tightening Torques
Cylinder HeadIf either diameter is less than 10.6 mm (0.42 in.), replace the cylinder head bolt.
Tighten the cylinder head bolts in sequence to 39 N-m (4.0 kgf-m, 29 lbf-ft).
Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it from the first step.
After torquing, tighten all cylinder head bolts in two steps (90° per step). If you are using a new cylinder head bolt, tighten the bolt an extra 90°.
Intake Manifold
Install the intake manifold (A) with a new gasket (B), and tighten the bolts and nuts in a crisscross pattern in two or three steps, beginning with the inner bolt.
Exhaust Manifold
Install the exhaust manifold (D) with a new gasket (E) and new self-locking nuts (F) and bolts (G), and tighten the bolts and nuts in a crisscross pattern in two or three steps, beginning with the inner bolt.
