Apply sealant to bolt No. 9.
Tighten all head bolts to 18 ft. lbs. (24 N.m) in specified sequence. See pic.
Tighten all head bolts in sequence (except bolt No. 9) to 27 ft. lbs. (35 N.m).
Re-tighten bolt No. 9 to 18 ft. lbs. (24 N.m).
Draw a line across head of each bolt with a marking crayon to mark position of bolt.
Tighten all bolts an additional 90 degrees (1/4 turn) in specified sequence.
