Cylinder head attachment bolts
Cylinder head bolts must only be used once .
So the cylinder head bolts should always be
replaced. The new cylinder head bolts have a
red/brown sealant on the thread.
Note:
-Because of the sealant used on the cylinder
head bolts, their untightening torque may be
very high!
-All M16 and M12 threaded holes must be
carefully cleaned with a screw tap before
the bolts are fitted.
-Once the bolts have been tightened to the
specified torque, the angular displacement
of the M16 bolts must immediately be
started.
-The sealant cannot be applied later.
