8. Measure the diameter of each cylinder head bolt at point A and point B.
9. If either diameter is less than 10.6 mm (0.42 in.), replace the cylinder head bolt.
10. Apply new engine oil to the threads and under the bolt heads of all cylinder head bolts.
11. 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.
