If alignment of the EGR hot tube is difficult,
complete the following:
a. Remove the clamps from the EGR hot
tube and remove the tube.
b. Remove the mounting nuts and remove
the EGR valve and gasket from the
exhaust manifold. Discard the gasket.
c. Install a new gasket and reinstall the
EGR valve. DO NOT tighten the
mounting nuts at this time. While the
nuts can be snug, the valve should be
allowed to shift within the limits of the
bolt holes.
d. Install new upper and lower gaskets
and clamps and reinstall the EGR hot
tube. Tighten the clamps to
specification, 110 lb-in (12.4 N폷m). The
EGR valve will “float” into the best
alignment position.
e. Tighten the EGR valve mounting nuts
to specification, 40 lb-ft (55 N폷m).
