Over heating -- followup and question

[Pete Masterson]

The radiator was painted. And I noticed that they paint all the
radiators in their shop that they're servicing ... there was a rack
with a bunch of radiators that were just painted... I saw that they
have a fan blowing air through the newly painted radiators ...
probably to keep the paint from clogging the air passages.

I guess you'd have to ask an engineer about the value of painting a
radiator. However, the trade off of heat retention vs. protection
from external corrosion might favor the paint.

I forgot to ask what material the new core was made of... I'll call
'em Monday and ask. (But I think it is aluminum.)

The new core has a very different design than the old core. The old
core had flattened tubes for the passage of water. The tubes were
lined up (like soldiers in formation). The new core has many more
round tubes that are set on a diagonal from one another. The
alignment is every other row. The radiator shop I used does radiator
rebuilds for one of the smaller local transit districts and they use
the same radiator design in the transit busses (that travel all over
the region in relatively hot weather and many hills.)
