13. Remove the front cylinder head cover (see above).
14. Remove the water pump (see chapter Cooling, heating and air conditioning systems).
15. Remove the steering pump drive pulley (44), - keeping the pulley from turning can be done by crimping the temporarily installed drive belt.
16. Unbolt the bracket (47).
17. On models without A/C, remove the bracket (46b). On models with A/C, remove the brackets (46) And (46a).
18. Remove the steering pump (45) and move it aside without disconnecting the hydraulic lines.
19. Turning the crankshaft in the normal direction, bring the piston of the first cylinder to a position of 20-30°after TDC (see arrows in illustration 5.7b).
20. Using locking rods (01) fix the camshafts.
21. Mark the position of the gas distribution chain relative to the camshaft sprockets with a marker (75 and 76).
22. Remove chain tensioner (14).
23. Remove Prom Stars (76) and inlet (75) camshafts.
Note. The sprocket mounting bolts must be replaced without fail.
24. Remove the intake shaft assembly with the regulator.
25. Remove the chain guide pins (11).
Note. During installation, the pins are seated on the sealant.
26. Remove the bolts (A) fastening the timing cover to the cylinder head.
Note. The bolts are equipped with TORX heads.
27. Remove the drive belt pulley assembly with built-in vibration damper (95).
28. Mark the timing cover bolts with a marker.
29. Turn out fixing bolts and remove a cover (65), - take care not to damage the head gasket.
30. Replace front crankshaft oil seal (see Section Replacing the front crankshaft oil seal).
31. Thoroughly clean the mating surfaces of the cover and crankcase.
32. Replace o-rings (66).
33. Lubricate the mating surface of the cover with sealant, making sure that the latter does not get into the oil reservoir (65a) gas distribution chain.
34. Installation is carried out in the reverse order - when installing the cover, pull the chain up, completely removing its slack in the lower part. Make sure all fasteners are tightened to the correct torque.

28. Installation is carried out in the reverse order - a cushion of sealant with a width of about 2.0 mm and a thickness of about 0.5 mm should be applied to the mating surface of the cover (make sure that the sealant does not get into the oil channels). Don't forget to replace the cover o-rings (19) and front crankshaft seal. Make sure all fasteners are tightened to the correct torque.
29. Finally, clear the memory of the on-board self-diagnosis system by first reading the DTCs stored in it (see chapter Engine Electrical Systems).
