Sealing flange (pulley end) - tightening torque and sequence   Note Renew the bolts tightened with specified tightening angle.   Caution Risk of damage to aluminium bolts when installing sealing flange. t  Do not use aluminium bolts to pull sealing flange onto cylinder block. t  Therefore have three steel bolts M6x20 to hand for pulling on the sealing flange (see the following description). –  Tighten bolts in 10 stages in the sequence shown. Stages 1 ... 3:

Stage	Bolts	Tightening torque
1.		Fit sealing flange with gasket on cylinder block
2.	-1-	Tighten for idler roller → Item
3.	-2, 3, 4-	Tighten steel bolts M6x20 to 9 Nm

Stages 4 ... 8:

Stage	Bolts	Tightening torque/angle specification
4.		Insert temperature regulator for engine oil cooler with cover
5.	-10-	Screw in bolts by hand until they make contact
6.	-1 … 19-	3 Nm
7.	-1 … 19-	3 Nm (procedure specified in order to allow for settling of sealing flange)
8.	-1 … 19-	turn 90° further

Stages 9 ... 11:

Stage	Bolts	Tightening torque/angle specification
9.	-2, 3, 4-	Unscrew steel bolts M6x20
10.	-2, 3, 4-	Insert aluminium bolts and tighten to 3 Nm
11.	-2, 3, 4-	Turn aluminium bolts 90° further
