WARM ENGINE

A warm engine is an engine which, having reached operating temperature, has not been at a standstill for more than thirty minutes.

Direction of rotation of the engine

The direction of rotation of the engine is clockwise, as seen from the timing gear end.

First cylinder of the engine

The first cylinder of the engine is the cylinder at the timing gear end.

Left-hand and right-hand side of the engine

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.

Tightening cylinder head attachment bolts

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.

1st phase

Tighten M12 in the order	94 Nm(1)

		5.2 TIGHTENING TORQUES
0		The tightening torques stated in this section are
		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
		tightening torque stated in the overview of
		standard tightening torques.
		When attachment bolts and nuts are to be
		replaced, it is important that they are of exactly
		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.

Tightening cylinder head attachment bolts

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.

1st phase
Tighten M16 in the	50 Nm(1)
order indicated
2nd phase
Tighten M16 in the
order indicated	150 Nm
Tighten M12 in the	94 Nm(1)
order indicated
3rd phase
M16 in the order
indicated in two stages of	60_ angular
	displacement

(1)Apply a drop of oil to bolts M16 and M12 on the abutting surface of the bolt heads.
