each cylinder head, in several passes, in the sequence
shown, then repeat for the other side, as shown.
Torque: 54 N´m (550 kgf´cm, 40 ft´lbf)
If any of the cylinder head bolts does not meet the torque speci-
fication, replace the cylinder head bolt.
(d) Mark the front of the cylinder head bolt head with paint.
(e) Retighten the cylinder head bolts by 90° in the numerical
order shown.
