Cylinder Head Installation

Cylinder Head Installation
Install the cylinder head in the reverse order of removal:
1. Install the new coolant separator in the engine block, when replacing the engine block.





2. Clean the cylinder head and engine block surface.
3. Install the new cylinder head gasket (A) and dowel pins (B) on the engine block. Always use a new cylinder head gasket.





4. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with the pointer (B) on the engine block.





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.), replace the cylinder head bolt.
8. Apply new engine oil to the threads and flange of all the cylinder head bolts.
9. Tighten the cylinder head bolts in sequence to 39 Nm (4.0 kgf-m, 29 lbf-ft) using a beam-type torque wrench. When using a preset-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 torqueing, tighten all cylinder head bolts in two steps (90° per step) using a torque angle gauge. 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 6 of the procedure. Do not loosen it back to the specified angle.





11. Install the rocker arm assembly.
12. Install the cam chain.
13. Tighten the three bolts (A) securing the evaporative emission (EVAP) canister purge valve bracket, and tighten the two bolts (B) securing the harness brackets.





14. Install the engine wire harness connectors and wire harness clamps from the cylinder head.
^ Four injector connectors
^ Engine coolant temperature (ECT) sensor 1 connector
^ Camshaft position (CMP) sensor A connector (Intake side)
^ Camshaft position (CMP) sensor B connector (Exhaust side)
^ Rocker arm oil control solenoid (VTEC solenoid valve) connector
^ Rocker arm oil pressure switch (VTEC oil pressure switch) connector

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





16. Install the positive crankcase ventilation (PCV) hose (A) and ground cable (B).





17. Install the exhaust manifold.
18. Install the intake manifold.
19. Install the EVAP canister hose (A) and brake booster vacuum hose (B).





20. Tighten the bolt securing the connecting pipe support bracket to the engine block.





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





22. Install the air intake duct (A), then connect the mass air flow (MAF) sensor/intake air temperature (IAT) sensor connector (B), and install the vacuum hose (C) and breather pipe (D).





23. Install the drive belt.
24. After installation, check that all tubes, hoses, and connectors are installed correctly.
25. 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.
26. Refill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open.
27. Do the crankshaft position (CKP) pattern clear/CKP pattern learn procedure.
28. Inspect the idle speed.
29. Inspect the ignition timing.
