Removal
CAUTION:
- Use fender covers to avoid damaging painted surfaces.
- To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal operating 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.
- Turn the crankshaft pulley so that the No. 1 piston is at top dead center.
1. Disconnect the negative terminal (A) from the battery.
2. Remove the engine room cover (A), engine cover (B) and radiator grill upper cover (C).
3. Loosen the drain plug (A) and drain the engine coolant. Remove the radiator cap (B) to speed draining.
WARNING:
Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.

(1) Remove the air duct (A).
(2) Disconnect the air flow sensor (AFS) connector (C).
(3) Disconnect the breather hose (B).
(4) Remove the resonator (F), the intake air hose (E) and air cleaner assembly (D).
5. Disconnect the radiator upper hose (A) and lower hose (B).
6. Remove the fuel hose (A), the purge control solenoid valve (PCSV) hose (B) and the brake booster vacuum hose (C).
7. Disconnect the heater hoses (A).
8. Remove the radiator & cooling fan assembly from the vehicle.
9. Turn the tensioner (B) clockwise and loosen, then remove the drive belt (A).
10. Remove the drive belt tensioner (A).
11. Remove the engine wiring harness from the cylinder head.
(1) Disconnect the engine coolant temperature sensor (ECTS) connector (A) and the CVVT oil control valve (OCV) connectors (B).
(2) Disconnect the alternator connector (A).
(3) Disconnect the ETC module connector (A).
(4) Disconnect the purge control solenoid valve (PCSV) connector (A) and the injector connectors (B).
(5) Disconnect the ignition coil connectors (A) and the wiring harness protector (B).
(6) Disconnect the knock sensor connectors (A), the camshaft position sensor (CMPS) connectors (B), the oxygen sensor (HO2S) connector (C), the condenser connector (D) and the ground line (E).
(7) Disconnect the variable intake system (VIS) solenoid valve connector (A) and the wiring harness protector (B).
(8) Disconnect the knock sensor connectors (A), the camshaft position sensor (CMPS) connectors (B), the crankshaft position sensor (CKPS) connector (C), the oxygen sensor (HO2S) connector (D), condenser connector (E) and the ground line (F).
(9) Disconnect the injector connectors (A).
(10) Disconnect the ignition coil connectors (A) and the wiring harness protector (B).
(11) Disconnect the oil pressure switch (OPS) connector (A), the CVVT oil control valve (OCV) connectors (B) and the air conditioner compressor switch connector (C).
12. Remove the oil level gauge (A).
13. Remove the oxygen sensor (HO2S) connector bracket (A).
14. Disconnect the PCV hose (A), the PCSV hose (B) and the water hoses (C) from the intake manifold module.
15. Remove the intake manifold module (A).
16. Remove the knock sensors (A) and then remove the wiring assembly bracket (B).
17. Remove the water hose (A).
18. Remove the ignition coils (A).
19. Remove the cylinder head cover (A).
20. Remove the cylinder head cover gasket (A) and oil seal (B).
21. Remove the oil pressure switch (OPS) wiring assembly and bracket (A).
22. Remove the engine coolant temperature sensor (ECTS) wiring assembly and bracket (A).
23. Remove the exhaust manifold heat protector (A).
24. Remove the exhaust manifold (A).
25. Remove the timing chain upper cover (A).
26. Remove the timing chain upper cover oil seal (A).
27. Remove the oil control valve (OCV) (A).
NOTE:
- Do not reuse the OCV when dropped.
- Keep the OCV clean.
- Do not hold the OCV sleeve (A) during servicing.
- When the OCV is installed on the engine, do not move the engine while holding the OCV yoke.
28. Remove the cam to cam guide (A).
