Tightening sequence of cylinder head bolts on 1.4-I engine
- stage 1 - 30 Nm;
- stage 2 - turn to 90° angle;
- stage 3 - turn to 90° angle
There are two centering pins for centering the cylinder head, so there is no need to screw in the guide pins.
Execution order
1. Using a steel ruler and feeler gauge, check the flatness of the mating surface of the cylinder head. Deviations from flatness should be no more than 0.05 mm.
2. Install the new cylinder head gasket onto the cylinder block surface with the TOP or OBEN marking facing up.
3. Gradually, in the sequence shown in the figure Sequence of tightening the cylinder head mounting bolts on the 1.4-I engine, tighten the cylinder head mounting bolts in several stages.
4. Clean the mating surfaces of the cylinder head and camshaft housing.
5. Apply a thin layer of AMV 188 003 sealant to the mating surface of the camshaft housing.
6. Install the supporting elements and rocker arms into the cylinder head in the same places where they were before removal. Check that the rocker arms are correctly positioned on the valves (1) and that they are securely fixed with the retaining clamps (2).
7. Lubricate the working surfaces of the camshaft lobes with clean engine oil.
8. Before installing the camshaft housing, screw the M6x70 guide studs into the outer holes of the cylinder head (indicated by arrows).
9. Install the camshaft housing and unscrew the guide studs. Screw in the new camshaft housing mounting bolts and tighten them crosswise to 10 Nm, then tighten them by 90° in the same sequence.
Warning: After installing the camshaft housing, the sealant must dry for at least 30 minutes before starting the engine.
