2. Drain the coolant.
3. Remove the camshaft belt (see photo) in the order discussed above. Follow the descriptions for the respective motors below.
Engines 1.4, 1.6 and 1.8 liters
4. Remove intake and exhaust manifolds (Chapter 4A). The cylinder head can also be removed without removing the manifolds by doing the following.
- A. Disconnect the exhaust pipe from the manifold.
- b. Disconnect the oxygen sensor and engine speed sensor connectors.
5. Remove the cylinder head cover, camshaft sprockets and toothed belt idlers.
6. Turn away bolts of fastening of the top cover of a belt to a head of cylinders.
7. Disconnect the connectors from the engine processor unit on the left side of the cylinder head.
8. Disconnect the hoses from the thermostat housing and the heater hoses. Turn away bolts and disconnect from a head of cylinders a branch pipe of system of cooling (see photo).
9. On 1.4 and 1.6 liter engines, remove the crankcase ventilation hose from the processor unit bracket, on 1.8 liter engines, unscrew the bolt and remove the oil indicator pipe.
10. In reverse order (see photo below) gradually loosen the bolts (making ⅓ of a turn per reception). Remove bolts with washers (see photo).
11. Remove the cylinder head. Remove the sticky head with light blows from a soft-faced hammer. Remove guide pins and gasket.
Engine 2.0L
12. Remove intake and exhaust manifolds (Chapter 4A). The cylinder head can also be removed without dismantling the manifolds by disconnecting the wires and hoses.
13. Remove the cylinder head cover, camshaft sprockets and toothed belt idlers.
14. Turn away bolts of fastening of the top cover of a belt to a head of cylinders.
15. If the intake manifold will not be removed, then unscrew the bolts and nuts and move the generator to the side by removing the brackets from the manifold.
16. Disconnect the throttle cable from the throttle pipe, the vacuum brake booster hose from the manifold, disconnect the fuel lines from the fuel pressure regulator.
17. Disconnect the heater hoses from the cylinder head, as well as the hose from the throttle pipe.
18. Disconnect the wires from the injectors.
19. Remove the final camshaft.
20. In reverse order (see photo below) gradually loosen the bolts (making ⅓ of a turn per reception) until the bolts begin to turn away by hand. Remove bolts with washers.
21. Remove the cylinder head. Remove the sticky head with light blows from a soft-faced hammer. Remove guide pins and gasket
Assembly preparation
22. Clean the split surfaces of the head and block, covering all holes to prevent dirt from entering. Lubricate the gaps in the pistons with grease, which then remove.
23. Check for damage on the split surfaces of the head and cylinder block (deep scratches, chips, etc.). Minor defects are removed with a needle file, serious damage is removed by grinding the block and head.
24. Check the deformation of the split surfaces of the head and block using a gauge and feeler gauge.
25. Clean the threads in the cylinder head and drive them with a tap.
26. Replace the cylinder head bolts.
Installation
27. Set the piston of the 1st cylinder to the TDC of the compression stroke and turn the crankshaft back 60°.
28. Wipe dry the split surfaces of the head and cylinder block. Make sure you have guide pins.
29. Put a new gasket on the cylinder block (the inscription OBEN / TOP should be facing up - photo). Install the cylinder head on the guide pins (see photo).
30. Tighten the cylinder head bolts in sequence (see photo) with the moment of the 1st stage of tightening. Tighten the bolts in the same sequence, first at the corner of the 2nd stage, then at the corners of the 3rd, 4th and 5th stages.
31. Install the removed parts in reverse order, following the description for the respective engines.
