REMOVAL
WARNING:
Perform the work when the exhaust and cooling system have completely cooled down.
1. Remove engine cover with power tool. Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
2. Remove air cleaner case and air duct. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
3. Remove front and rear engine undercover and front cross bar with power tool.
4. Disconnect heated oxygen sensors 2 (bank 1 and bank 2) harness connectors.
5. Using heated oxygen sensor wrench (SST), remove heated oxy-
gen sensors 2 (bank 1 and bank 2).
CAUTION:

Be careful not to damage heated oxygen sensor.

Discard any heated oxygen 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; replace with a new
sensor.

6. Remove exhaust mounting bracket between right/left catalytic converter and transmission. Refer to EX-3,
"EXHAUST SYSTEM" .
7. Remove three way catalyst (right and left bank).
8. Disconnect heated oxygen sensor 1 (bank 1 and bank 2) harness connectors and remove harness clip.
9. Using heated oxygen sensor wrench (SST), remove heated oxy-
gen sensor 1 (bank 1 and bank 2).
CAUTION:

Be careful not to damage heated oxygen sensor.

Discard any heated oxygen 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; replace with a new
sensor.
10. Remove water pipes on both right and left side. Refer to CO-28, "
WATER OUTLET AND WATER PIPING"
.
11. Remove exhaust manifold cover (right and left bank).
12. Loosen nuts in the reverse order as shown in the figure to
remove exhaust manifold with power tool.
NOTE:
Disregard the numerical order No. 7 and No. 8 in removal.
13. Remove exhaust manifold gaskets.
CAUTION:
Cover engine openings to avoid entry of foreign materials.

INSPECTION AFTER REMOVAL
Surface Distortion

Check the surface distortion of the exhaust manifold mating sur-
face with straightedge and feeler gauge.

If it exceeds the limit, replace exhaust manifold.
INSTALLATION
Note to the following, and install in the reverse order of removal.
Exhaust Manifold Gasket

Install in direction shown below. (Follow same procedure for
both banks.)

Locate thick side of port connecting part on right side from tech-
nician’s view.

Locate round press in thick side of port connecting part above
center level line of port.
Exhaust Manifold

If stud bolts were removed, install them and tighten to the speci-
fied torque below.

Install exhaust manifold in the numerical order as shown in the
figure.
NOTE:
Tighten nuts No. 1 and No. 2 in two steps. The numerical order
No. 7 and No. 8 shows second step.
Heated Oxygen Sensor
CAUTION:

Before installing a new heated oxygen sensor, 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.Limit : 0.3 mm (0.012 in)
