Cylinder Head Removal

Engine removal is not required for this procedure.

CAUTION: To avoid damaging the cylinder head, wait until the engine coolant temperature drops below 100°F (38°C) before loosening the retaining bolts.

NOTE:
- Inspect the timing belt before removing the cylinder head.
- Turn the crankshaft pulley so that the No. 1 piston is at Top Dead Center (TDC).
- Mark all emissions hoses before disconnecting them.
- Anti-theft radios have a coded theft protection circuit. Be sure to get the customer's code number before.
- Disconnecting the battery.
- Removing the No. 32 (7.5 A) fuse from the underhood fuse/relay box.
- Removing the radio.
After service, reconnect power to the radio and turn it on.
When the word "CODE" is displayed, enter the customer's 5-digit code to restore radio operation.

1. Disconnect the negative terminal from the battery.
2. Drain the engine coolant.
- Remove the radiator cap to speed draining.
3. Relieve fuel pressure.

WARNING: Do not smoke while working on fuel system, keep open flame or spark away from work area. Drain fuel only into an approved container.





4. Disconnect the fuel feed hose.





5. Remove the intake air duct.





6. Remove the breather hose, water bypass hose and Evaporative Emission (EVAP) control canister hose.





7. Remove the fuel return hose and Positive Crankcase Ventilation (PCV) hose.





8. Remove the brake booster vacuum hose, water bypass hose and vacuum hose.
9. Remove the throttle cable.





10. Remove the throttle control cable (automatic transmission only).

NOTE:
- Take care not to bend the cable when removing it. Always replace any kinked cable with a new one.
- Adjust the throttle cable and throttle control cable when installing.

11. Remove the engine wire harness connectors and wire harness clamps from the cylinder head and the intake manifold.
- Four fuel injector connectors
- Intake Air Temperature (IAT) sensor connector
- Engine Coolant Temperature (ECT) sensor connector
- TDC/CKP/CYP sensor connector
- Ignition coil connector
- ECT gauge sending unit connector
- Throttle Position (TP) sensor connector
- Manifold absolute pressure (MAP) sensor connector
- Idle Air Control (IAC) valve connector
- EVAP purge control solenoid valve connector
- Crankshaft Speed Fluctuation (CKF) sensor connector
12. Remove the spark plug caps and distributor from the cylinder head.





13. Remove the upper radiator hose, heater hose and water bypass hose.





14. Remove the splash shield.





15. Remove the engine ground cable. Remove the adjusting bolt and mounting bolts, then remove the Power Steering (P/S) pump belt and P/S pump.
- Do not disconnect the P/S hoses.
16. Remove the Air Conditioning (A/C) compressor belt.
17. Remove the alternator belt.





18. Remove the cruise control actuator.





19. Remove the side engine mount.





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





22. Remove the camshaft pulleys and back cover.





23. Remove the exhaust manifold.





24. Remove the intake manifold.

Adjusting Screw Location:

25. Loosen the locknuts and adjusting screws.





26. Remove the camshaft bolts, then remove the camshaft holders, camshafts and rocker arms.

Cylinder Head Bolts Loosing Sequence:

27. Remove the cylinder head bolts, then remove the cylinder head.

CAUTION: To prevent warpage, unscrew the bolts in sequence 1/3 turn at a time; repeat the sequence until all bolts are loosened.
