Tightening Torques
Cylinder HeadMeasure the diameter of each cylinder head bolt at point A and point B.
If 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:
Crankshaft Bearing
Tighten the bearing cap bolts, in sequence, to 29 N-m (3.0 kgf-m, 22 lbf-ft).
Tighten the bearing cap bolts an additional 56°
Tighten the 8 mm bolts, in sequence, to 22 N-m (2.2 kgf-m, 16 lbf-ft)
Connecting Rod
Tighten the connecting rod bolts 29 N-m (3.0 kgf-m, 22 lbf-ft)
Tighten the connecting rod bolts an additional 90°.
Crankshaft Pulley
Tighten the bolt to 49 N-m (5.0 kgf-m, 36 lbf-ft) with a torque wrench and 19 mm socket. Do not use an impact wrench.
Tighten the pulley bolt an additional 90°.
