This bulletin is a clarification of the revised cylinder head bolt torque and tightening sequence bulletin.
The updated sequence and specification is as follows:
Tighten the cylinder head bolts to 44 ft.lbs (60 N-m) in the order
shown in illustration. Use the J 36660-A torque angle meter in order to
rotate the cylinder head bolts an additional 95 degrees.
Please note that 95° is just a little more than a 1/4 turn, not 1/2 turn, or
from 12 o’clock to 3 o’clock on the dial. Do not tighten beyond this
specification, otherwise the bolts will be overstressed and the gaskets
may suffer damage.
