Cylinder Head Installation

Cylinder Head Installation

1. Clean the cylinder head and the engine block surface.

2. Clean and install the oil control orifices (A) with new O-rings (B).





3. Install the dowel pins (C) and the new cylinder head gaskets (D).

4. Clean the timing belt pulleys, the 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. Install the cylinder heads on the engine block.

8. Measure the diameter of each cylinder head bolt at point A and point B.





9. If either diameter is less than 11.3 mm (0.44 in), replace the cylinder head bolt.

10. Apply new engine oil to the threads and under the bolt heads of all cylinder head bolts.

11. Torque the cylinder head bolts in sequence to 29 Nm (3.0 kg-m, 22 lb-ft) using a beam-type torque wrench. When using a preset click-type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it from the first step.










12. After torquing, tighten all cylinder head bolts in two steps (90 ° per step) using the sequence shown in step 11. If you are using a new cylinder head bolt, tighten the bolt an extra 90 °.

NOTE: Remove the cylinder head bolt if you tightened it beyond the specified angle, and go back to step 8 of the procedure. Do not loosen it back to the specified angle.





13. Install the timing belt.

14. Adjust the valve clearance.

15. Install the cylinder head covers.

16. Install the water passage.

17. Install the injector bases.

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





19. Install the evaporative emission (EVAP) canister joint with the bracket.

20. Install the engine mount control solenoid valve bracket to the rear cylinder head.






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





22. Install the front warm up three way catalytic converter (front WU-TWC) and the rear warm up three way catalytic converter (rear WU-TWC).

23. Connect the following engine wire harness connectors, and install the wire harness clamps to the cylinder head:

- Six injector connectors
- Knock sensor connector
- Engine coolant temperature (ECT) sensor 1 connector
- Engine mount control solenoid valve connector
- Camshaft position (CMP) sensor connector
- Rocker arm oil control solenoid connector
- Rocker arm oil pressure switch connector
- Two air fuel ratio (A/F) sensor connectors
- Two secondary heated oxygen sensor (secondary HO2S) connectors

24. Install the six ignition coils.

25. Install the intake manifold.

26. Install the alternator.

27. Do the battery terminal reconnection procedure.

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

29. Inspect for fuel leaks. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode (do not operate the starter) so the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation three times, then check for fuel leakage at any point in the fuel line.

30. Refill the radiator with engine coolant, and bleed the air from the cooling system.

31. Check for fluid leaks.

32. Do the engine control module (ECM)/powertrain control module (PCM) idle learn procedure.

33. Do the crankshaft position (CKP) pattern clear/CKP pattern learn procedure.

34. Inspect the idle speed.

35. Inspect the ignition timing.

36. Install the engine compartment covers.
