INSPECTION AFTER REMOVAL
Surface Distortion
●
Using straightedge and feeler gauge, inspect surface distortion
of intake manifold collector and intake manifold surface.
INSTALLATION
●
Install in the reverse order of removal paying attention to the following.
Tightening Intake Manifold
●
Temporarily attach before installing intake manifold collector.
●
Tighten in numerical order as shown in the figure.

●
Using heated oxygen sensor wrench, remove heated oxygen
sensor.
CAUTION:
●
Be careful not to damage heated oxygen sensor.
●
When using heated oxygen sensor wrench, tighten to the
middle of specified torque because length of tool may
induce sight indication increase. (Do not tighten to the
maximum specified torque)
●
Do not over torque the heated oxygen sensor. Doing so
may cause damage to the heated oxygen sensor, result-
ing in the MI coming on.
6.
Remove exhaust manifold cover.
7.
Loosen mounting nuts in reverse order shown in figure to
remove exhaust manifold and catalytic converter assembly.
INSPECTION AFTER REMOVAL
Surface Distortion
●
Use a reliable straightedge and feeler gauge to check the flat-
ness of exhaust manifold fitting surface.
INSTALLATION
●
Install in the reverse order of removal after this step.
●
Tighten mounting nuts for exhaust manifold and catalytic con-
verter assembly in order shown in figure.
●
Before installing exhaust manifold support, apply liquid gasket to
contact surface on engine side.
Use Genuine Liquid Gasket or equivalent.
Installation of Heated Oxygen Sensor
CAUTION:
●
Do not over torque the heated oxygen sensor. Doing so may cause damage to the heated oxygen
sensor, resulting in the MI coming on.
