Removing the cylinder head

Bolt of fastening of an asterisk and a drive of the distributor of ignition on a camshaft operating inlet valves

Attention! The cylinder head can only be removed when the engine is cold.

1. Remove the negative cable from the battery.

2. On engines with a carburetor, remove the air filter.

3. On engines with a fuel injection system, remove the air intake, plenum chamber and air filter.

4. Drain the coolant from the cooling system by unscrewing the plug at the bottom right of the radiator.

5. Disconnect the radiator return hose and the expansion tank hose from the cylinder head.



6. Disconnect the coolant supply hose to the heater from the cylinder head.

7. Disconnect the crankcase ventilation hose from the head cover.


8. On engines with a fuel injection system, disconnect the vacuum hoses from the intake manifold.

9. Disconnect the fuel inlet and outlet hoses from the pressure regulator.

10. Disconnect the electrical wires from the radiator fan.

11. Unscrew the bolt and disconnect the ground bar from the left rear of the cylinder head.

12. On engines with a fuel injection system, disconnect and remove the wires from the engine management system.

13. Disconnect the center high voltage wire from the ignition coil.

14. Unscrew the upper nut securing the intake manifold to the exhaust manifold.

15. Raise the front of the vehicle and unscrew the two lower nuts securing the front exhaust pipe to the exhaust manifold.

16. Lower the car.

17. Disconnect the high voltage wires from the spark plugs and remove the ignition distributor cap.

18. Unscrew the spark plugs.

19. Remove the ignition distributor.

20. Disconnect the accelerator pedal cable. In a carbureted engine, unscrew the throttle cable together with the holder, and in a fuel-injected engine, disconnect the link from the throttle body after removing it from the plastic clip side.

21. When removing the cylinder head with the fuel system and intake manifold, disconnect all wires, hoses and cables, unscrew the intake manifold and fuel baffle fastening nuts.

22. If it is necessary to remove the cylinder head without the fuel system and intake manifold, unscrew the intake manifold and fuel baffle fastening nuts and move them to the side without disconnecting the wires, hoses and cables from them.


23. Unscrew 11 bolts and 4 fastening nuts and remove the cylinder head cover.

24. Remove timing chain and sprockets (see subsection 3.2.2.1).

25. Gradually and alternately unscrew the nuts and remove the camshaft mounting covers together with the oil supply pipe. The camshaft covers are marked for future reinstallation. In the absence of marking, before removing the covers, they must be marked.

26. Remove camshafts from cylinder head. There is a green mark on the camshaft that controls the exhaust valves. If there is no mark, mark the camshafts.



27. Remove the hydraulic valve lifters and place them in the appropriate oil containers for later reinstallation.

28. Loosen the 13 cylinder head bolts gradually and sequentially in reverse order to tightening.

Attention! Reusing the cylinder head bolts is not recommended.

29. Remove the cylinder head and set it on two wooden blocks to avoid damaging the valves.

30. Remove the cylinder head gasket and guide bushings.
