Removal

CAUTION:
- Use fender covers to avoid damaging painted surfaces.
- To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

NOTE:
- Mark all wiring and hoses to avoid misconnection.
- To release the fuel system pressure before removing the engine assembly, start the engine with the fuel pump relay removed. And then turn off the ignition switch after engine stops.

1. Remove the engine cover (A).




2. Disconnect the battery terminals (A). Disconnect the negative terminal first.

3. Remove the air cleaner assembly.
(1) Remove the air duct (B).
(2) Disconnect the breather hose (C).
(3) Disconnect the air intake hose and then remove the air cleaner assembly (D).

Tightening torque
Hose clamp bolt:
2.9 - 4.9N.m (0.3 - 0.5kgf.m, 2.2 - 3.6lb-ft)
Air cleaner assembly bolts:
7.8 - 9.8N.m (0.8 - 1.0kgf.m, 5.8 - 7.2lb-ft)





NOTE:
- Install the air intake hose while the plate of the hose clamp must be in line with the stopper of the hose.
- Install the air intake hose while the groove of hose must be matched to the protrusion of the throttle body.




4. Disconnect the ECM connector (A).




5. Remove the ECM (A) and then remove the battery (B).

Tightening torque
ECM bracket bolts & nut :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)




6. Remove the battery tray (A).

Tightening torque :
8.8 - 13.7N.m (0.9 - 1.4kgf.m, 6.5 - 10.1lb-ft)




7. Remove the under cover (A).

Tightening torque:
6.9 - 10.8 N.m (0.7 - 1.1 kgf.m, 5.1 - 8.0 lb-ft)








8. Loosen the drain plug, and drain the engine coolant. Remove the radiator cap to drain with speed.
9. Disconnect the radiator upper hose (A) and lower hose (B).








10. Recover the refrigerant and then remove the high pressure pipe and low pressure pipe (A).




11. Disconnect the (+) cable (A), connector (B) from the fuse/relay box.
