INSPECTION AFTER REMOVAL
Surface Distortion

Using straightedge and feeler gauge, check the surface distor-
tion of exhaust manifold and three way catalyst assembly mating
surface.

If it exceeds the limit, replace exhaust manifold and three way
catalyst assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.
Exhaust Manifold

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

Heated Oxygen Sensor

Install heated oxygen sensors in the original position.

Install referring the following if the installation positions cannot
be identified.
CAUTION:

Before installing a new heated oxygen sensor, clean exhaust system threads using heated oxygen
sensor thread cleaner (commercial service tool) and apply anti-seize lubricant (commercial ser-
vice tool).

Do not exceed the specified torque heated oxygen sensor. Doing so may cause damage to heated
oxygen sensor, resulting in the “MIL” coming on.
