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

8. Apply engine oil to the threads and under the bolt heads of all cylinder head bolts.

9. 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 from the first step.
