Removing
The order of tightening the cylinder head bolts
1. Raise the hood and place it vertically.
2. Disconnect the negative cable from the battery.
3. Drain the coolant.
4. Remove the alternator drive belt.
5. On the left head of the block of cylinders: turn away bolts. Disconnect the base plate along with the power steering pump (11) from the tensioner and secure side to side with attached tubes.
6. On the right cylinder head: unscrew the alternator from the bracket and secure it to the side with the wires attached.
7. Remove covers of heads of the block of cylinders.
8. Remove the front timing cover.
9. Bring the engine to a position of 45°before TDC of the piston of the first cylinder.
10. Mark the relative position of the camshaft sprockets and the timing chain.
11. Remove the timing chain tensioner.
12. Remove the upper guide arms.
13. Turn away sprockets of final camshafts and regulators of camshafts before removal.
14. Remove the inlet pipeline.
15. On the left cylinder head: Disconnect the cooling system pipe at the rear of the cylinder head.
16. On the right head of the block of cylinders: turn away a directing pipe of the gauge of level of liquid АТ.
17. Turn away system of release from final collectors.
18. Disconnect the exhaust system from the bracket on the AT.
19. On the right head of the block of cylinders: turn away conducting from below on the right.
20. Before removing the cylinder head, remove the bolts with washers (a), (b), (c), (d), (e), (f).
21. The head bolts are loosened using a screwdriver-insert (1) in the reverse order shown in the illustration.
22. Install a lifting eye on the cylinder head before removal. To do this, unscrew the second and fourth camshaft bearing caps on the right and left heads, install the lug with guide bushings.
23. Attach a lifting chain to the lifting eyes, lift the cylinder heads and remove them from the engine.
24. Check up contact surfaces of heads of the block of cylinders.
25. Replace the cylinder head gaskets. Check the mounting bolts and replace them if necessary.
