An integral plastic bracket, generally indicated at (34) in FIGS. 1-6
and at (134) in FIGS. 7-9, is in gripping engagement with each
of first and second manifolds. Each bracket and includes a pocket complementary
to and surrounding the associated manifold or and a pair of spaced flanges extending
from the pocket to engage the faces of the heat exchanger core. Each bracket and
also includes a plurality of recesses disposed about projections along the manifolds
and for preventing the bracket and from moving along the associated manifold. The
flanges have inside surfaces engaging the faces of the heat exchanger core that
are closer together at a distance (B) than the transverse dimension (A) of the
manifolds and for retaining the bracket and on the heat exchanger core.
