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 ordershown in illustration. Use the J 36660-A torque angle meter in order torotate 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, orfrom 12 o’clock to 3 o’clock on the dial. Do not tighten beyond thisspecification, otherwise the bolts will be overstressed and the gasketsmay suffer damage.
