Cylinder Head

Cylinder head





Tighten the cylinder head bolts in sequence to 29 Nm (3.0 kgf-m, 22 ft. lbs.) 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.
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°.
Tighten the 8 mm bolts (A) to 22 Nm (2.2 kgf-m, 161 ft. lbs.).





Measure the diameter of each cylinder head bolt at point A and point B. If either diameter is less than 11.5 mm (0.45 inch), replace the cylinder head bolt.
