Cylinder Head Removal

Cylinder Head Removal
Engine removal is not required for this procedure.

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 retaining bolts. Mark all wiring and hoses to avoid Disconnection. 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 battery negative terminal.
3. Drain the engine coolant.





4. Remove the intake air duct.





5. 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 cable when removing it. Always replace any kinked cable with a new one.





6. Remove the breather hose (A) and Positive Crankcase Ventilation (PCV) hose (B).
7. Relieve fuel pressure.





8. Remove the fuel feed hose (A) and fuel return hose (B).





9. Remove the brake booster vacuum hose (A) and vacuum hoses (B).





10. Remove the Evaporative Emission (EVAP) canister hose (A), vacuum hose (B) and P/S hose clamp (C).





11. Remove the three water bypass hoses (A).





12. Remove the mounting bolts (A), then remove the Power Steering (P/S) pump belt (B) and pump without disconnecting the P/S hoses.





13. Remove the alternator belt.
^ 1 Loosen the alternator mounting bolt (A).
^ 2 Loosen the alternator locknut (B).
^ 3 Loosen the adjusting bolt (C).
^ 4 Remove the alternator belt (D).





14. Disconnect the alternator wire harness.
^ 1 Pull up the lock (A), then release the wire harness tie (B).
^ 2 Pull back the boot and remove the 6 mm nut (c).
^ 3 Disconnect the connector (D) from the alternator.





15. Remove the upper radiator hose (A), lower radiator hose (B) and heater hose (C).
16. Remove the engine wire harness connectors and wire harness clamps from the cylinder head and the intake manifold.
^ Four injector connectors
^ Intake Air Temperature (IAT) sensor connector
^ Idle Air Control (IAC) valve connector
^ Throttle Position (TP) sensor connector
^ Manifold Absolute Pressure (MAP) sensor connector
^ Primary Heated Oxygen Sensor (primary HO2S) connector (F23A1, F23A5 engine)
^ Air Fuel Ratio (A/F) sensor connector (F23A4 engine)
^ Engine Coolant Temperature (ECT) sensor connector
^ Radiator fan switch connector Coolant temperature gauge sending unit connector ('98-00 models)
^ Exhaust Gas Recirculation (EGR) valve connector CKP/TDC sensor connector
^ VTEC solenoid valve connector (F23A1/F23A4 engines)
^ VTEC oil pressure switch connector (F23A1/ F23A4 engines)
17. Remove the spark plug caps and distributor from the cylinder head.
18. Support the engine with a jack and wood block under the oil pan.





19. Remove the stop (A) and ground cable (B), then remove the upper bracket (C).





20. Remove the cylinder head cover.
21. Remove the balancer belt and timing belt.





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





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





24. Remove the intake manifold.





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.
