Notes

This article has been updated with TSB 02-06-01-003B, 4/15/08
This bulletin is being revised to include a Notice advising that the cylinder hea boltsgraphic are NOT TO BE RE-USED . Please discard Corporate Bulletin Number 02-06-01-003A.

Notice: This component uses torque-to-yield bolts. When servicing this component, do not re-use the bolts. New torque-to-yield bolts must be installed. Re-using used torque-to-yield bolts will not provide proper bolt torque and clamp load. Failure to install NEW torque-to-yield bolts may lead to engine damage

 

Tighten the NEW cylinder head bolts to 60 Nm (44 lb ft) in the order shown. Use the J 36660-A torque angle meter in order to rotate the cylinder head bolts an additional 95 degrees .
