Cylinder Head Removal

Cylinder Head Removal

NOTE: Use fender covers to avoid damaging painted surfaces. To avoid damaging the wire and terminals, 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. Keep the cam chain away from magnetic fields.

1. Relieve fuel pressure.
2. Remove the engine cover.
3. Drain the engine coolant.
4. Remove the air cleaner.
5. Remove the intake manifold.
6. Disconnect the knock sensor (A), then remove the harness clamp (B) and the connecting pipe (C).





7. Disconnect the CMP sensor (A) and the ECT sensor 1 (B), then remove the harness clamp (C).





8. Remove the eight ignition coils.
9. Remove the harness holder and the breather hose.
10. Disconnect the purge control solenoid valve connector (A), then remove the clip (B).





11. Disconnect the purge joint from the clamp (C), then remove the fuel pipe bolt (D) and remove the purge control solenoid stay bolts (E).
12. Remove the upper radiator hose (A), lower radiator hose (B), water bypass hose (C), and heater hoses (D).





13. Remove the drive belt.
14. Turn the crankshaft pulley so its TDC mark lines up with the pointer.
15. Remove the water pump.
16. Remove the cylinder head cover.
17. Remove the under floor three way catalytic converter (TWC) and the warm-up three way catalytic converter.
18. Remove the crankshaft pulley.
19. Support the engine with a jack and a wood block under the oil pan.
20. Remove the ground cable, then remove the side engine mount bracket.
21. Disconnect the CKP sensor (A) and the harness clamp (B), then remove the dipstick tube (C).





22. Remove the chain case.





23. Make a reference mark (A) across the camshaft sprocket and the cam chain.





24. Loosely install the crankshaft pulley.
25. Apply new engine oil to the sliding surface of the cam chain tensioner through the oil return hole in the cylinder head.





26. Hold the crankshaft pulley and set the socket wrench (A) on the camshaft sprocket bolt.





27. Turn the camshaft clockwise to compress the cam chain tensioner, then install the 6 x 1.0 mm bolt (B) in the bolt hole (C) in the engine block through the cam chain tensioner (D).

NOTE:
^ Turning torque should not exceed 44 Nm (4.5 kgf-m, 33 ft. lbs.) when turning the camshaft.
^ Do not turn the camshaft counterclockwise.

28. Hold the camshaft with a 27 mm open-end wrench, then remove the camshaft sprocket.





29. Remove the top bolt that secures the cam chain guide.





30. 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.





31. Remove the cylinder head.
