Installation

INSTALLATION
Install the cylinder head in the reverse order of removal:

NOTE:
- Always use a new head gasket.
- Cylinder head and cylinder block surface must be clean.
- "UP" mark on the camshaft pulley should be at the top.
- Turn the crankshaft so the No. 1 piston is at TDC.
- Clean the oil control orifice before installing.
- Do not use the upper cover and lower cover to store removed items.
- Clean the upper cover and lower cover before installation.





1. Cylinder head dowel pins must be aligned.

2. Position the camshaft correctly.

3. Tighten the cylinder head bolts sequentially in four steps.

1st step: (1) - (10) 20 Nm (2.0 kgs.cm, 14 ft.lbs.)
2nd step: (1) - (10) Nm (5.0 kgs.cm, 36 ft.lbs.)
3rd step: (1) - (10) Nm (6.8 kgs.cm, 49 ft.lbs.)
4th step: (1), (2) Nm (6.8 kgs.cm, 49 ft.lbs.)





CYLINDER HEAD BOLTS TORQUE SEQUENCE:

NOTE:
- We recommend using a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and not to overtighten.
- If a bolt makes any noise while you are torquing it, loosen the bolt, and retighten it from the 1st step.

4. Install the intake manifold and tighten the nuts in a crisscross pattern in two or three steps, beginning with the inner nuts.
- Always use a new intake manifold gasket.

5. Install the exhaust manifold and tighten the nuts in a crisscross pattern in two or three steps, beginning with the inner nut.
- Always use a new exhaust manifold gasket.

6. Install the exhaust manifold bracket. Install the exhaust pipe A and the bracket, then install the cover.

7. Install the timing belt.

8. Adjust the valve clearance.





9. Install the head cover gasket in the groove of the cylinder head cover. Seat the recesses for the camshaft first, then work it into the groove around the outside edges.

NOTE:
- Before installing the head cover gasket, thoroughly clean the seal and the groove.
- When installing, make sure the head cover gasket is seated securely in the corners of the recesses with no gap.





10. Apply liquid gasket to the head cover gasket at the four corners of the recesses.

NOTE:
- Use liquid gasket, Part No. 08718-0001 or 08718-0003.
- Check that the mating surfaces are clean and dry before applying liquid gasket.
- Do not install the parts if five minutes or more have elapsed since applying liquid gasket. Instead, reapply liquid gasket after removing old residue.
- After assembly, wait at least 30 minutes before filling the engine with oil.





11. When installing the cylinder head cover, hold the head cover gasket in the groove by placing your fingers on the camshaft holder contacting surfaces (top of the semicircles).
Set the spark plug seal on the spark plug tube.
Once the cylinder head cover is on the cylinder head, slide the cover slightly back and forth to seat the head cover gasket.

NOTE:
- Before installing the cylinder head cover, clean the cylinder head contacting surfaces with a shop towel.
- Do not touch the parts where liquid gasket was applied.
- Take care not to damage the spark plug seals when installing the cylinder head cover.
- Visually check the spark plug seals for damage.
- Replace any washer that is damaged or deteriorated.





12. Tighten the nuts in two or three steps. In the final step, tighten all bolts, in sequence, to 9.8 Nm (1.0 kgs.cm, 7.2 ft.lbs.).

NOTE: After assembly, wait at least 30 minutes before filling the engine with oil.

13. After installation, check that all tubes, hoses and connectors are installed correctly.
