5. Install the cylinder head on the engine block.

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

7. If either diameter is less than 10.6 mm (0.42 in),


7. If either diameter is less than 10.6 mm (0.42 in), replace the cylinder head bolt.

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

9. Torque the cylinder head bolts in sequence to 39 N-m {4.0 kgf-m, 29 Ibf-ft). Use 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.

10. After torquing, tighten all cylinder head bolts in two


10. After torquing, tighten all cylinder head bolts in two steps (90 Р’В° per step) using the sequence shown in step 9. If you are using a new cylinder head bolt, tighten the bolt an extra 90 Р’В°.

NOTE: Remove the cylinder head bolt if you tightened it beyond the specified angle, and go back to step 6 of the procedure. Do not loosen it back to the specified angle.

11. Install the rocker arm assembly (see page 6-93).

12. Install the cam chain (see page 6-64).

13. Connect the following engine wire harness

connectors, and install the wire harness clamps to the cylinder head:

 - Engine coolant temperature (ECT) sensor 1 connector

 - Camshaft position (CMP) sensor A (Intake) connector

 - Camshaft position (CMP) sensor B (Exhaust) connector

 - Two rocker arm oil control solenoid connectors

 - Two rocker arm oil pressure switch connectors

 - Evaporative emission (EVAP) canister purge valve connector

 - Variable valve timing control (VTC) oil control solenoid valve connector

 - Engine oil pressure switch connector

14. Install the two bolts (A) securing the connecting pipe.

15. Connect the water bypass hose (B).


15. Connect the water bypass hose (B).

16. Connect the upper radiator hose (A), the heater hoses (B), and the water bypass hose (C).


18. Connect the four fuel injector connectors (A), the


18. Connect the four fuel injector connectors (A), the engine mount control solenoid valve connector (B), and install the ground cables (C).

19. Connect the fuel feed hose (A) (see page 11-316), then


19. Connect the fuel feed hose (A) (see page 11-316), then install the quick-connect fitting cover (B).

20. Connect the EVAP canister hose (A).


20. Connect the EVAP canister hose (A).

21. Install the catalytic converter (see page 11-339).


21. Install the catalytic converter (see page 11-339).

22. Install the intake manifold (see page 9-6).

23. Install the drive belt (see page 4-30).

24. Install the strut brace (if equipped) (see page 20-306).

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

26. Inspect for fuel leaks. Turn the ignition switch to ON (II) (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.

27. Refill the radiator with engine coolant, and bleed the air from the cooling system (see step 5 on page 10-6).

28. Check for fluid leaks.

29. Do the powertrain control module (PCM) idle learn procedure (see page 11-293).

30. Do the crankshaft position (CKP) pattern clear/CKP pattern lean procedure (see page 11-5).

31. Inspect the idle speed (see page 11-292).

32. Inspect the ignition timing (see page 4-19).
