REMOVAL
WAR NING :
Perform the work when the exhaust and cooling system have completely cooled down.
1. Remove engine room cover (RH and LH). Refer to EM-14, "
ENGINE ROOM COVER" .
2. Remove engine cover with power tool. Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
3. Remove air cleaner case and air duct. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
4. Remove front and rear engine undercover with power tool.
5. Remove exhaust front tube and three way catalysts (right and left bank). Refer to EX-3, "
EXHAUST SYS-
TEM" .
6. Disconnect air fuel ratio sensor 1 (bank 1 and bank 2) harness connectors and remove harness clip.
1. Air fuel ratio sensor 1 (bank 1) 2. Exhaust manifold cover (right bank) 3. Exhaust manifold (right bank)

7. Using the heated oxygen sensor wrench (SST), remove air fuel
ratio sensor 1 (bank 1 and bank 2).
CAUTION:
Be careful not to damage air fuel ratio sensor 1.
Discard any air fuel ratio sensor 1 which has been
dropped onto a hard surface such as a concrete floor;
replace with a new sensor.
8. Remove exhaust manifold cover (right and left bank).
9. Loosen mounting nuts in the reverse order as shown in the fig-
ure to remove exhaust manifold with power tool.
NOTE:
Disregard the numerical order No. 7 and 8 in removal.
10. Remove 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 a straightedge and a feeler gauge.
If it exceeds the limit, replace exhaust manifold.
INSTALLATION
Note 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 specified torque below.
Install exhaust manifold and tighten mounting bolts in numerical
order as shown in the figure.
NOTE:
Tighten nuts No. 1 and 2 in two steps. The numerical order No. 7
and 8 shows second step.
Air Fuel Ratio Sensor
CAUTION:
Before installing a new air fuel ratio 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.
Do not over torque air fuel ratio sensor. Doing so may cause damage to air fuel ratio sensor,
resulting in the “MIL” coming on.
