Cylinder Head: Installation

1. Before installing head bolts, clean and lubricate threads with engine oil. Install head gasket over locating dowels. Ensure gasket is installed on correct side. Install cylinder head over dowels.
2. Tighten cylinder head bolts in correct sequence. See Fig 1. Using 5-step torque turn method, tighten head bolts to specification as follows:
   • First, tighten bolts No. 1-8 to 35 ft. lbs. (47 N.m).
   • Second, tighten bolts No. 1-8 to 55 ft. lbs. (75 N.m).
   • Third, tighten bolts No. 1-8 (again) to 55 ft. lbs. (75 N.m).
   • Fourth, add 1/4 turn to bolts No. 1-8. DO NOT use a torque wrench for this step.
   • Fifth, tighten bolts No. 9-11 to 21 ft. lbs. (28 N.m).

To complete installation, reverse removal procedure.
