CYLINDER HEAD AND VALVE ASSEMBLY:

Removal
1. Remove the V-belt.
2. Remove the crank pulley.
3. Remove the timing belt cover.
4. Remove the timing belt.
5. Remove the cam sprockets.
6. Remove the intake manifold.
7. Remove the bolt which installs the A/C compressor bracket on cylinder head.
8. Remove the camshaft.
9. Remove the cylinder head bolts in alphabetical sequence shown in the figure.
Leave bolts (A) and (D) engaged by three or four threads to prevent the cylinder head from falling.





10. While tapping the cylinder head with a plastic hammer, separate it from cylinder block. Remove the bolts (A) and (D) to remove cylinder head.





11. Remove the cylinder head gasket.

CAUTION: Be careful not to scratch the mating surface of cylinder head and cylinder block.

12. Similarly, remove the cylinder head (RH).

Installation
1. Install the cylinder head and gaskets on cylinder block.

CAUTION:
^ Use new cylinder head gaskets.
^ Be careful not to scratch the mating surface of cylinder head and cylinder block.

2. Tighten the cylinder head bolts.
^ Apply a coat of engine oil to the washers and bolt threads.
^ Tighten all bolts to 29 Nm (3.0 kgf-m, 22 ft. lbs.) in alphabetical sequence.
^ Tighten all bolts to 69 Nm (7.0 kgf-m, 51 ft. lbs.) in alphabetical sequence again.
^ Back off all bolts by 180° first; back them off by 180° again in reverse order of installation.
^ Tighten all bolts to 49 Nm (5.0 kgf-m, 36 ft. lbs.) in alphabetical sequence.
^ Tighten all bolts 80 to 90° in alphabetical sequence.
^ Tighten all bolts by 40 to 45° in alphabetical sequence again.

CAUTION: Do not tighten the bolts by more than 45°.

^ Further tighten all bolts (A) and (B) by 40 to 45°.

CAUTION: Ensure that the total "re-tightening angle" in the previous two steps do not exceed 90°.
