Refit

1. Remove bolts securing cylinder liner clamps 18G 1736 to cylinder block and remove clamps.
2. If necessary, decarbonise piston crowns and combustion chambers.
3. Clean mating faces of cylinder head and cylinder block.
4. Clean oil and coolant passages.
5. Clean inlet and exhaust manifold mating faces on cylinder head.
6. Clean location dowels and fit to cylinder block.
7. Clean cylinder head bolts and wipe dry. Apply clean engine oil to bolt threads and under head of bolts.
8. Fit new cylinder head gasket, dry, to cylinder block.
9. With assistance, fit cylinder head onto cylinder block, ensure that dowels are correctly located.
10. Carefully enter cylinder head bolts, DO NOT DROP. Screw bolts into place by hand.
11. Temporarily fit camshaft timing gears, fit and lightly tighten bolts.
12. Using tool 12-182, rotate camshafts to gain access to cylinder head bolts beneath camshaft reluctor rings.

13. Working in the sequence shown, progressively tighten the cylinder head bolts to 20 Nm. Use a suitable angle torque gauge and tighten all bolts in sequence 180°. Then tighten all bolts in sequence a further 180°.
14. Remove camshaft gears.
15. Fit camshaft cover gasket. See this section.
16. Connect multiplugs to hydraulic control solenoids.
17. Connect multiplug to CMP sensor.
18. Connect multiplug to oil temperature sensor.
19. Connect multiplugs to coolant temperature sensors.
20. Connect hoses to coolant elbow on cylinder head and tighten clips.

21. Fit new exhaust manifold gasket, position exhaust manifold, fit and tighten nuts in the sequence shown to 45 Nm.
22. Secure HO2S multiplug in bracket at rear of cylinder head.
23. Fit spacer onto stud, position heat shield on exhaust manifold. Fit and tighten nut to 25 Nm and speed bolts to 10 Nm.
24. Position camshaft front timing belt rear cover, fit bolts and tighten to 9 Nm.
25. Position camshaft timing belt tensioner pulley to cylinder head, fit Allen bolt but do not tighten at this stage.
26. Fit tensioner backplate bolt, hold tensioner in the fully OFF position, tighten tensioner backplate bolt to 10 Nm.
27. Clean camshaft gears and mating faces on camshafts.
28. Fit camshaft gears to their respective camshafts, ensuring that the drive pins are located in correct slots on gears.
29. Fit bolts and washers securing camshaft gears to camshafts. Using tool 12-182 restrain camshaft gears and tighten bolts to 65 Nm.
30. Using 12-182, align camshaft gear timing marks and fit camshaft gear locking tool, 18G 1570.
31. Fit camshaft timing belt. See this section.
32. Fit inlet manifold gasket. See this section.
33. Fit engine compartment access cover.
