SUBJECT:
Heat Exchanger Rubber End Cap
Many heat exchangers supplied on our various products incorporate a
molded rubber end cap to facilitate inspection of the tubes.
There have been occasions on which engine overheating has been caused
by the improper positioning of this rubber end cap.
It is absolutely essential that the molded channel running across the
inside of the
cap be positioned over the baffle of the heat exchanger,
according to the
drawing below.
In any cases of engine overheating where such a rubber end cap is used,
it should be checked for proper positioning along with other routine
troubleshooting.
