My opinion is- that the entry end must be correctly shaped (funnel-shaped) to cause the majority of coolant to enter the tube, rather than "spill" around it.
Unless the tube material has significant corrosion, I've always been able to re-shape it well enough.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
