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 to 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 speci-
fied torque below.

Install exhaust manifold in the numerical order as shown in the
figure.
NOTE:
Tighten nuts No. 1 and No. 2 in two steps. The numerical order
No. 7 and No. 8 shows second step.
Heated Oxygen Sensor
CAUTION:

Before installing a new heated oxygen 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-
