Cylinder Head Installation

Cylinder Head Installation
Install the cylinder head in the reverse order of removal:

1. Clean the cylinder head and block surface.





2. Clean and install the oil control orifices (A) with new O-rings (B).
3. Install the dowel pins (C) and new cylinder head gaskets (D).
4. Clean the timing belt pulleys, timing belt guide plate, and the upper and lower covers.





5. Set the timing belt drive pulley to top dead center (TDC) by aligning the TDC mark (A) on the tooth of the timing belt drive pulley with the pointer (B) on the oil pump,





6. Set the camshaft pulleys to TDC by aligning the TDC marks (A) on the camshaft pulleys with the pointers (B) on the back covers.
7. Apply new engine oil to the threads and flanges of the cylinder head bolts.





8. Tighten the cylinder head bolts sequentially in three steps.

NOTE: Perform each step twice.

1st Step Torque: 39 Nm (4.0 kgf-m, 29 ft. lbs.)
2nd Step Torque: 69 Nm (7.0 kgf-m, 51 ft. lbs.)
3rd Step Torque: 98.1 Nm (10.0 kgf-m, 72.3 ft. lbs.)
Use 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.
9. Install the water passage.
10. Install the fuel rails.





11. Install the connector bracket to the front cylinder head.





12. Install the harness clamp bracket to the rear cylinder head.





13. Connect the fuel feed hose, then install the quick-connect fitting cover (A).





14. Install the purge joint (A) to the bracket, then install the evaporative emission (EVAP) canister hose (B).
15. Install the front warm up three way catalytic converter (front WU-TWC) and rear warm up three way catalytic converter (rear WU-TWC).
16. Install the timing belt.
17. Adjust the valve clearance.
18. Install the cylinder head covers.
19. Install the intake manifold.
20. Install the A/C compressor belt.
21. After installation, check that all tubes, hoses, and connectors are installed correctly.
22. Inspect for fuel leaks. Turn the ignition switch ON (II) (do not operate the starter) so the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.
23. Refill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open.
24. Inspect the idle speed.
25. Inspect the ignition timing.
