The procedure requires some experience. Only the most important instructions for the experienced mechanic are given here.
General installation instructions are for the 1.6l ALZ petrol engine.
When unscrewing the cylinder head bolts, follow the sequence.
Cylinder head cover
1. Before installing the cylinder head cover, coat both edges of the sealing surfaces of the camshaft/cylinder head bearing caps at the front (arrows on the accompanying illustration) and behind one drop of sealant, e.g. AMV 174 004 01 (Ø 5 mm).
2. The sequence of unscrewing the cylinder head cover bolts is the reverse of that indicated in the accompanying illustration.
3. Tighten first by hand, in the sequence from 1 to 13 and then in the same sequence - with a torque of 9Nm. The arrow shows the connection of the crankcase ventilation hose.
Installing the cylinder head
1. The gasket number of the cylinder head cover must be at the top.
2. When installing the cylinder head, both cams of the first cylinder must point up (arrows on the accompanying illustration).
3. Watch the centering sleeves in the cylinder block.
4. Tighten the cylinder head bolts in the sequence from 1 to 10 in 4 steps, given in Specifications efforts.
