INSPECTION AFTER REMOVAL
Surface Distortion

Check the surface distortion of the each exhaust manifold flange
mating surface with straightedge and 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 exhaust manifold gasket with its directional protrusion set upward.
Refer to the figure of components on former page. Refer to EM-182, "
Removal and Installation" .
Exhaust Manifold

Install exhaust manifold and tighten mounting nuts in numerical
order as shown in the figure.
NOTE:
Tighten mounting nuts No. 1 to 4 in two steps. The numerical
order No. 9 to 12 shown second steps.
Heated Oxygen Sensor

Install heated oxygen sensors in the original position.

Install referring the following if the installation positions cannot
be identified.
*: The length of glass tube of bank 2 is longer than the one
of bank 1.
CAUTION:

Before installing a new heated oxygen sensor, clean
exhaust system threads using oxygen sensor thread
cleaner (commercial service tool: J-43897-18 or J-43897-12), and apply anti-seize lubricant (com-
mercial service tool).

Do not over torque heated oxygen sensor. Doing so may cause damage to the heated oxygen sen-
sor, resulting in “MIL” coming on. Limit : 0.3 mm (0.012 in)
