Cylinder Head Removal

Removal

NOTE:
^ Use fender covers to avoid damaging painted surfaces.
^ To avoid damage, unplug the wiring connectors carefully while holding the connector portion.
^ To avoid damaging the cylinder head, wait until the engine coolant temperature drops below 100°F (38°C) before loosening the cylinder head bolts.
^ Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact other wiring or hoses, or interfere with other parts.

1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.
2. Disconnect the negative cable from the battery.
3. Drain the engine coolant.








4. Remove the throttle cable (A) and cruise control cable (B) by loosening the locknuts (C), then slipping the cable ends out of the accelerator linkage. Take care not to bend the cables when removing them. Always replace any kinked cable with a new one.





5. Remove the intake resonator.





6. Disconnect the Intake Air Temperature (IAT) sensor connector (A), and remove the breather hose, then remove the air cleaner housing (B).





7. Remove the brake booster vacuum hose (A) and positive crankcase ventilation (PCV) hose (B).
8. Relieve fuel pressure.





9. Remove the evaporative emission (EVAP) canister hose.





10. Remove the ground cable (A), upper radiator hose (B), lower radiator hose (C), heater hose (D) and water by pass hose (E).





11. Remove the two bolts securing the connecting pipe, then remove the connecting pipe from the water passage.





12. Remove the adjusting plate mounting bolt (A), locknut (B) and mounting bolt (C), then remove the power steering (P/S) pump belt (D) and pump without disconnecting the P/S hoses.
13. Remove the alternator.





14. Remove the A/C hose bracket (A) and P/S hose bracket (B).
15. Remove the engine wire harness connectors and wire harness clamps from the intake manifold.
^ Idle air control (IAC) valve connector
^ Throttle position (TP) sensor connector
^ Manifold absolute pressure (MAP) sensor connector
^ Evaporative emission (EVAP) canister purge valve connector
^ Engine coolant temperature (ECT) sensor connector
^ Radiator fan switch connector
^ Crankshaft position (CKP) sensor connector
^ Camshaft position (CMP) (top dead center (TDC) sensor connector
^ Exhaust gas recirculation (EGR) connector (D17A2, D17A6 engines)
^ VTEC solenoid valve connector (D17A2, D17A6 engines)
^ VTEC oil pressure switch connector (D17A2, D17A6 engines)
^ Oil pressure sensor connector
16. Support the engine with a jack and wood block under the oil pan.





17. Remove the upper bracket.








18. Remove the cover (A), then remove the exhaust manifold (B).





19. Remove the intake manifold.
20. Remove the four ignition coils.





21. Remove the throttle cable clamps (A) and harness holder (B) from the cylinder head cover.





22. Remove the cylinder head cover.
23. Remove the timing belt.





24. Remove the camshaft pulley (A) and back cover (B).





25. Remove the cylinder head bolts. To prevent warpage, unscrew the bolts, in sequence, 1/3 turn at a time. Repeat the sequence until all bolts are loosened.
26. Remove the cylinder head.
