AWD : Removal and Installation


REMOVAL

1.Drain engine coolant. Draining Engine Coolant.
2.Remove engine cover. Exploded View.
3.Remove cowl top extension. Exploded View.
4.Remove front tube. Exploded View
5.Remove catalyst converter support bracket (lower).
6.Remove A/F sensor 1 and heated oxygen sensor 2.
- Use heated oxygen sensor wrench [SST: KV-10117100 (J-3647-A)], remove A/F sensor 1 and heated oxygen sensor 2.

CAUTION:
- Never damage air fuel ratio sensor 1.
- Discard any sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one.
7.Remove catalyst converter shroud (upper).
8.Remove bolts and nut of catalyst converter turbocharger side.
9.Remove heat insulator. Exploded View.
10.Remove catalyst converter support bracket (upper).
11.Remove catalyst converter. And keep a service area.
NOTE:
Slide the catalyst converter in a lateral direction to obtain work space for removing turbocharger.
12.Remove turbocharger. Exploded View.
13.Pull up and remove catalyst converter.
14.Remove gasket.

INSTALLATION






1.Install gasket between turbocharger and catalyst as shown in the figure.





2.Install catalyst converter with the following procedure.





- Tighten in numerical order as shown in the figure.
- Install catalyst converter (base on stud position 1).
- Temporary assemble 2 (no priority).
- Temporary assemble 3, 4.
- Tightening 5, 6 and 7.
- Tightening again 8, 9 and 10.
- Temporary assemble 11.
- Tightening 12,13,14,and 15.
3.Note the following, and install in the reverse order of removal.
A/F sensor 1
- Using heated oxygen sensor wrench [SST: KV-10117100 (J-3647-A)], install A/F sensor 1.

CAUTION:
- Before installing a new sensors, clean exhaust system threads using heated oxygen sensor thread cleaner tool (Commercial Service Tool: J-43897-18 or J-43897-12) and apply anti-seize lubricant.
- Never apply excessive torque to sensor 2. Doing so may cause damage to sensor 2, resulting in the "MIL" illuminating.
- Prevent rust preventives from adhering to the sensor body.
