If either diameter is less than 10.6 mm (0.42 in), replace the cylinder head bolt.

Except PZEV models

Torque the cylinder head bolts in sequence to 39 Nm (4.0 kg-m, 29 lb-ft)






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 °
