Note: The figure shows the cylinder head of a 1.6 L engine. The cylinder head of a 1.4 L engine differs slightly in design and is characterized by a different tightening torque for the fastening screws.
- 1. Valve cover
- 2. Gasket
- 3. Screw
29 Nm + 90° -> loosen all screws -> 29 Nm + 90° (1.6 l engine)
34 Nm + 90° -> loosen all screws -> 34 Nm + 90° (1.4 l engine) - 4. Cylinder head
- 5. Cylinder head gasket
- 6. Cylinder block
Removal the cylinder head
Note: The cylinder head removal procedure is described for a removed engine. If it is necessary to remove the head on a vehicle, follow the appropriate steps in the engine removal procedure.
Before disconnecting, label connectors and hoses.
1. Remove the ignition coils.
2. Remove the intake and exhaust manifolds.
3. Remove the timing belt.
4. Disconnect the crankcase ventilation hose (1) and vacuum hose (2) from the cylinder head cover
5. Remove the cylinder head cover bracket (3).
6. Unscrew the screws (4) in the indicated sequence and remove the cylinder head cover (5) with the gasket.
7. Holding the camshaft hexagon (6), unscrew the screw (7) with the key (8) and remove the pulley. Tightening torque: 79-98 Nm.
For 1.6L engines only
8. Remove the chain tensioner (9).
9. Remove the timing phase adjustment oil valve (10).
10. Remove the timing phase adjustment valve oil filter (11).
For all models
11. Remove the bearing caps (12) and camshafts (13).
12. Unscrew the screws (14) of the engine support bracket.
13. Loosen the cylinder head bolts one by one in the sequence shown
Caution: If the order specified for unscrewing the screws is not followed, the cylinder head may be damaged.
14. Remove the cylinder head.
Installation
Note: Clean and wash all parts before assembly. Turn the crankshaft and set the piston of the 1st cylinder to TDC.
15. Remove engine oil from the surfaces of the cylinder head and block.
Caution: carefully remove all remaining liquids (coolant and oil) from the threaded holes of the cylinder block. If a certain volume of incompressible liquid appears in the blind threaded hole when tightening the cylinder head mounting screw, a rupture of the cylinder block wall may occur.
16. Install a new gasket on the cylinder block.
17. Install the cylinder head on the cylinder block, having first installed the centering bushings.
18. Apply a thin coat of motor oil to the threads and under the screw heads.
19. Install the washers and tighten the mounting screws in the sequence shown.
Tightening torque: 29 Nm + 90° -> to weaken completely -> 29 Nm + 90°(1.6L);
34 Nm + 90° -> to weaken completely -> 34 Nm+ 90° (1.4 l).
20. Install the engine support bracket. Tightening torque: 44-54 Nm.
For 1.6L engines only
21. Install the timing phase adjustment valve oil filter. Tightening torque. 40-50 Nm.
22. Install the timing phase adjustment oil valve. Tightening torque: 10-12Nm.
Caution: If the oil valve has been subjected to mechanical impact, replace it. Do not hold the valve by the working part during installation.
23. Install the chain tensioner. Tightening torque: 8-10 Nm.
24. Install the chain by aligning the painted chain links with the marks on the camshaft and timing chain sprockets as shown.
25. Install the camshafts (15) and bearing caps (16). Tightening torque 12-14 Nm
26. Using a drift, install the camshaft oil seal.
27. Install the gasket (17) on the cylinder head cover (18).
Note: Please clean the cover surface thoroughly before installation.
For all models
28. Apply sealant to the cylinder head cover gasket.
Note: Install the cap within 5 minutes after applying the sealant. Do not start the engine for at least 30 minutes after installing the cap.
29. Install the cylinder head cover (19) and tighten the mounting screws (20) in the specified sequence. Tightening torque: 8-10 Nm.
30. Further installation is carried out in the reverse order of removal.
