Cylinder Head
Tighten the cylinder head bolts in sequence to 39 Nm (4.0 kgf-m, 29 ft. lbs.) using 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) using a torque angle gauge. If you are using a new cylinder head bolt, tighten the bolt an extra 90°.
