EXHAUST MANIFOLD AND TURBOCHARGERNJEM0102S02RemovalNJEM0102S0201+Loosen exhaust manifold mounting nuts in the reverse order
specified in the figure.
+Rotate the exhaust manifold and turbocharger assembly so
that the rear side (EGR tube mounting side) faces upward. And
then pull out the assembly from between the engine and the
air conditioning piping.
CAUTION:
Be careful not to deform each turbocharger piping when pull-
ing out the assembly.
