Removal

Removal

Engine removal is not required for this procedure.

CAUTION:
- Use fender covers 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 misconnection.
- Inspect the timing belt before removing the cylinder head.
- Turn the crankshaft pulley so that the No. 1 piston is at top dead center.

1. Disconnect the terminals (A) and remove the battery (B).




2. Remove the engine cover.
3. Remove the air duct(A).




4. Remove the radiator cap to speed draining.
5. Loosen the radiator drain plug(A) and drain engine coolant.




6. Remove the intake air hose and air cleaner assembly.
(1) Disconnect the PCM connectors (A).
(2) Remove the intake air hose (B) and the air cleaner assembly (C).




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




8. Remove the heater hoses (A).




9. Remove the engine wire harness connectors and wire harness clamps from the cylinder head and the intake manifold.
(1) OCV(Oil control Valve) connector (A).
(2) Oil temperature sensor (OTS) connector (B).
(3) Engine coolant temperature (ECT) sensor connector (C).
(4) Ignition coil connector (D).




(5) TPS(Throttle Position Sensor) connector (A).
(6) ISA(Idle Speed Actuator) connector (B).
(7) CMP(Camshaft Position Sensor) connector (C).
(8) Four fuel injector connectors.
(9) Knock sensor connector (D).
(10) PCSV(Purge Control Solenoid Valve) connector (E).




(11) Front heated oxygen sensor connector.
10. Remove the fuel inlet hose (A) from delivery pipe and brake booster vacuum hose(B).




11. Remove the cylinder head cover.
(1) Disconnect the spark plug cables and do not pull on the spark plug by force.

NOTE:
Pulling on or bending the cables may damage the conductor inside.

(2) Disconnect the positive crankcase ventilation (P.C.V) hose (A) and the breather hose (B) from the cylinder head cover.
(3) Disconnect the accelerator cable (C) and the auto-cruise cable (D) from the cylinder head cover.




12. Remove the timing belt.
13. Remove the exhaust manifold and intake manifold.
14. Remove camshaft sprocket.
(1) Hold the hexagonal head wrench (A) portion of the camshaft with a wrench (B), and remove the bolt and camshaft sprocket (C).





CAUTION:
Be careful not to damage the cylinder head and valve lifter with the wrench.

15. Remove the timing chain auto tensioner (A).




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




17. Remove the OCV(oil control valve) (A).




18. Remove the OCV(oil control valve) filter (A).




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





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.
