Fig. 2.200. Tightening the cylinder head mounting bolts
Loosen all bolts and tighten them to the specified torque (Fig. 2.200).
Tightening torque of cylinder head bolts (engine temperature approximately 20°C): 25 Nm +(58–62°) +(43–47°).
When tightening the cylinder head mounting bolts, a combined torque-angular tightening method is used.
Fig. 2.201. Sequence of tightening the cylinder head bolts
Tighten the bolts in the sequence shown in Figure 2.201.
Note: Warm up the engine to operating temperature. After the engine has cooled down, repeat the bolt tightening procedure.
