Tightening Torques and Sequences

Cylinder Head Torque and Sequence

Tighten the cylinder head bolts in sequence to 29 N-m (3.0 kgf-m, 22 lbf-ft) using a beam-type torque wrench. When using a preset-type torque wrench, be sure to torque 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.

Rear:

After torquing, tighten all cylinder head bolts in two steps (90 ° per step) using the sequence shown in step 12. If you are using a new cylinder head bolt, tighten the bolt an extra 90 °.

Head Bolt Reuse/Replace






Measure 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.

Intake Manifold Torque and Sequence

Intake manifold. Tighten the bolts and nuts sequentially in three steps. Always use a new intake manifold gasket.










Main Bearing Cap Torque and Sequence






Tighten the bearing cap bolts to 74 N-m (7.5 kgf-m, 54 lbf-ft), and the bearing cap side bolts to 49 N-m (50 kgf-m, 36 lbf-ft) in the proper sequence

bearing half and the cap, and tighten the bolts.

NOTE:
Apply new engine oil to the bolt threads and flanges.
Do not rotate the crankshaft during inspection.






Crankshaft Pulley Torque

Tighten the bolt. Do not use an impact wrench.






Hold the pulley with the holder handle (A) and the holder attachment (B). Tighten the bolt to 64 N-m (6.5 kgf-m, 47 lbf-ft) with a torque wrench and a 19 mm socket (C).






Mark the bolt head (D) and the crankshaft pulley (E) as shown, then tighten the bolt an additional 60 ° (The mark on the bolt head lines up with the mark on the crankshaft pulley).

Flexplate (Drive Plate)






Tighten the eight bolts in a crisscross pattern in two or more steps.
