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.

Front:





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.










Camshaft Pulley/Grar Torque

Apply new engine oil to the threads of the camshaft pulley mounting bolt (A). Install the back cover (B), then install the camshaft pulley (C).
