(2) Disconnect the VIS (Variable intake system) connector (A), the OPS (Oil pressure switch) connector (B), the injector extension connector (C), the knock sensor connector (D), the alternator connector (E) and the A/C compressor switch connector (F).
(3) Disconnect the ignition coil connectors (A), the fuel pump connector (B) and the intake OCV (Oil control valve) connector (C).
(4) Disconnect the ETC (Electronic throttle control) connector (A) and MAPS (Manifold absolute pressure sensor) & IATS (Intake air temperature sensor) connector (B).
(5) Disconnect the ECTS (Engine coolant temperature sensor) connector (A) the exhaust CMPS (Camshaft position sensor) connector (B), the condenser connector (C), the CKPS (Crankshaft position sensor) connector (D) and the oxygen sensor connector (E).
(6) Disconnect the intake CMPS (Camshaft position sensor) connector (A) and the PCSV (Purge control solenoid valve) connector (B).
11. Disconnect the (+) cable (A) from the fuse/relay box and the front connector (B). Then remove the wiring protector.
12. Remove the transaxle wire harness connectors and control cable from the transaxle. .
13. Disconnect the ATF cooler hoses. .
14. Disconnect the heater hoses (A).
NOTE:
When installing the heater hoses, install as shown in illustrations.
15. Disconnect the fuel hose (A) and PCSV (Purge control solenoid valve) hose (B).
16. Disconnect the return hose (A) and suction hose (B).

20. Remove the lower arms (A).
21. Remove the stabilizer bar links (A).
22. Remove the tie rod ends (A).
23. Disconnect the drive shafts from the axle hubs.
24. Support the sub frame (A) with a floor jack, and then remove the sub frame mounting bolts and nuts.
Tightening torque
Sub frame mounting bolts & nuts :

NOTE:
- After removing the sub frame mounting bolt, the engine and transaxle assembly may fall downward, and so support them securely with floor jack.
- Verify that the hoses and connectors are disconnected before removing the engine and transaxle assembly.

27. Remove the engine and transaxle assembly by lifting vehicle.
CAUTION:
When removing the engine and transaxle assembly, be careful not to damage any surrounding parts or body components.
Installation
Installation is in the reverse order of removal.
Perform the following :
- Adjust a shift cable.
- Refill engine with engine oil.
- Refill a transaxle with fluid.
- Refill a radiator and a reservoir tank with engine coolant.
- Clean battery posts and cable terminals and assemble.
- Inspect for fuel leakage.
- After assemble the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes.
- Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.
- Bleed air from the cooling system.
- Start engine and let it run until it warms up. (until the radiator fan operates 3 or 4 times.)
- Turn Off the engine. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system.
- Put radiator cap on tightly, then run the engine again and check for leaks.
