1. Install the camshaft adjuster. To do this, screw the flanged shaft (16) new bolts (wrench size T40). Tighten the bolts as follows: first with a torque wrench with a torque of 20 Nm, then with an open-end wrench tighten another 90° (1/4 turn).
2. Turning to the left, fit the intake camshaft gear (13) with setting piston (14) and spherical spring (14a), while it will engage with the flanged shaft. The position of the flanged shaft must be set in advance. Painted markings must match.
3. Place the control chain on the intake camshaft gear. In this case, the markings made during dismantling on the control chain and the sprocket must match.
4. tighten the nut (6) with a torque of 65 Nm, with the locking slot facing outwards.
5. Insert an anchor (2), while the clamping sleeve on the armature must be above the blunting of the control piston (18).
6. Shoulder bolt (1) tighten as follows: with a torque wrench to 5 Nm, then tighten in the same direction by 90° (1/4 turn). At the same time, hold the anchor (2) for flats with an open-end wrench SW24.
7. Screw the exhaust camshaft gear, and for the 1.8 / 2.0 liter engine, additionally the intake shaft gear with the control chain superimposed with new bolts (key size T40). The markings on the sprocket and chain must match. Tighten the bolts as follows: with a torque wrench to 20 Nm, then tighten in the same direction with an open end wrench by 90° (1/4 turn).
8. Install the chain tensioner.
Attention! Pull lock pins out of camshafts.
9. Connect the exhaust pipe.
10. Fit the coolant hose behind the cylinder head and secure with hose clamps.
11. Screw the guide tubes of the engine and automatic transmission oil level gauges to the cylinder head.
12. Coat the sealing surfaces of the front cover (23) cylinder heads with sealant 002 989 0020 10 or other sealant.
13. Install two bolt relief sleeves (1) (thread diameter 8 mm) behind the cover. 56. Install a new coolant O-ring and insert the cap.
14. screw bolts (1) on both sides with a torque of 20 Nm, and the bolts (2) (thread diameter 6 mm) with a moment of 10 Nm.
15. Install the lambda probe wire.
16. Fit the bleed hoses to the cylinder head.
17. Screw the crankshaft position sensor holder to the rear of the cylinder head.
18. Screw the intake manifold to the cylinder head.
19. Install a new gasket, tighten the bolts evenly in a cross pattern to 20 Nm.
20. Install coolant regulator (thermostat).
21. Fill with coolant.
22. Install the cylinder head cover.
23. Connect wire "masses" battery.
24. Set the time on the clock.
25. Enter the radio's anti-theft code.
26. Warm up the engine to operating temperature and check for leaks.
Attention! If oil leaks due to a leak in the cylinder head gasket, an oil change is recommended.
