different from the standard tightening torques
stated in the overview of the standard tightening
torques. The other threaded connections which
are not stated must therefore be tightened to the

When attachment bolts and nuts are to be

the same length and property class as the ones
removed unless stated otherwise.

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.

Apply a drop of oil underneath the bolt heads
(on their abutting surface). Sealant also reduces
the frictional resistance, which means that no oil

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.

Note:
Apply a drop of oil underneath the bolt heads
(on their abutting surface). Sealant also reduces
the frictional resistance, which means that no oil
must be applied to the thread.
