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 the following, and install in the reverse order of removal.
Exhaust Manifold Gasket

Install exhaust manifold gasket in direction shown in the figure.
Exhaust Manifold

If stud bolts were removed, install them and tighten to the specified torque below.

Install mounting exhaust manifold 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 shown second step.

Install referring to the following if the installation positions cannot
be identified.
*: Air fuel ratio sensor 1 is the same for both bank 1 and
bank 2.
CAUTION:

Before installing a new air fuel ratio sensor 1 and heated
oxygen sensor 2, clean exhaust system threads using oxygen sensor thread cleaner (commercial
service tool: J-43897-18 or J43897-12) and apply anti-seize lubricant (commercial service tool).

Do not over torque air fuel ratio sensor 1 and heated oxygen sensor 2. Doing so may cause dam-
age to air fuel ratio sensor 1 and heated oxygen sensor 2, resulting in the “MIL” coming on.Glass tube color
