Cylinder Head Assembly-Removal

CYLINDER HEAD ASSEMBLY

COMPONENTS:

REMOVAL

Engine removal is not required for this procedure.

CAUTION:
^ Use Fender cover to avoid damaging painted surfaces.
^ To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature before removing it.
^ When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket.
^ To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

NOTE:
^ Mark all wiring and hoses to avoid mis-connection.
^ Inspect the timing belt before removing the cylinder head.
^ Turn the crankshaft pulley so that the No. 1 piston is at top dead center.

2. Remove the engine cover.
3. Remove the under cover(A).





4. Drain the engine coolant. Remove the radiator cap to speed draining.
5. Remove the intake air hose and air cleaner assembly.
1) Disconnect the breather hose(B) from intake air hose(D).
2) Remove the intake air hose(D) and air cleaner upper cover(C).





3) Disconnect the ECM connector(A) and ECM connector(B) (A/T only).
4) Remove the air cleaner element and air cleaner lower cover(C).





6. Remove the battery tray(A).





7. Remove the upper radiator hose(A) and lower radiator hose(B).





8. Remove the heater hoses(A).
9. Remove the fuel hose(B).





10. Remove the accelerator cable(A) by loosening the lock-nut, then slip the cable end out of the throttle linkage.
11. Disconnect the TPS (Throttle Position Sensor) connector(B) and the MAP sensor connector(C).





12. Remove the engine wire harness connectors and wire harness clamps from cylinder head and the intake manifold.
1) Disconnect the rear oxygen sensor connector (A).
2) Disconnect the air conditioner compressor switch connector (B).
3) Disconnect the knock sensor connector (C).
4) Disconnect the injector connectors(No.3,4) (D).
5) Disconnect the injector connectors(No.1,2) (E)





6) Remove the wire harness bracket(A).
7) Disconnect the ISA (Idle Speed Actuator) connector (B).





8) Disconnect the front oxygen sensor connector(A).
9) Disconnect the CKP(Crankshaft Position Sensor) connector (B).
10) Disconnect the OCV(Oil Control Valve) connector (C).





11) Disconnect the ignition coil connector(A).
12) Disconnect the ignition coil condenser connector(B).
13) Disconnect the CMP(Camshaft Position Sensor) connector(C).
14) Disconnect the ground cable(D).
15) Remove the wire harness bracket(E).





13. Disconnect the hose(A) of the PCSV (Purge Control Solenoid Valve) side.
14. Remove the brake booster vacuum hose(B).





15. Remove the power steering pump and fix the pump to vehicle with a wire.
16. Remove the ignition coil.
17. Remove the exhaust manifold.
18. Remove the intake manifold.
19. Remove the timing belt.
20. Remove the cylinder head cover.
21. Remove the camshaft sprocket.
22. Remove the timing chain auto tensioner(A).





23. Remove the camshaft bearing caps(A) and camshafts (B).





24. Remove the OCV(Oil Control Valve)(A).





25. Remove the OCV(Oil Control Valve) filter(A).





26. Remove the engine mounting support bracket fixing bolts(A).





27. Remove the cylinder head bolts, then remove the cylinder head.
1) Using 8 mm hexagon wrench, uniformly loosen and remove the 10 cylinder head bolts, in several passes, in the sequence shown.





CAUTION: Head warpage or cracking could result from removing bolts in an incorrect order.

2) Lift the cylinder head from the dowels on the cylinder block and replace the cylinder head on wooden blocks on a bench.

CAUTION: Be careful not to damage the contact surfaces of the cylinder head and cylinder block.
