TIGHTENING TORQUES

TIP
Cylinder head bolt
First, tighten the cylinder head bolts to 40 N·m (4.0 kgf·m, 30 lb·ft) in the proper tightening sequence
and remove them. Retighten the cylinder head bolts to 23 N·m (2.3 kgf·m, 17 lb·ft) in the proper tight-
ening sequence. Tighten all bolts to reach the specified angle (90
) in a diagonal sequence, and then
tighten the cylinder head bolts further to reach the specified angle (60
) in the proper tightening se-
quence. (The first and second time, be sure to apply molybdenum disulfide grease to the bolt threads
and seats as well as to both sides of the washers.)
