Re: Change of radiator core affecting cooling performance in 1949, 23rd series

Howard,

Thank you. So the application of the heavier duty fan by Packard, I think is making the point that a larger radiator needs more air flow. (Based on the literature, this seems to compensate for the lower fluid flow rate)

I guess now the question is, do I live with the larger radiator and try to make it work by increasing the airflow? Or as a purist, do I try to get the car back to original and work towards better cooling at idle (by increasing the fluid flow with the smaller radiator).

One quick test that I can make is to slip a regular 110v fan in front of the radiator while it is idling to see how the cooling works with increased air flow. (Obviously, this won't be in place while the car is moving but it confirm the point about air flow at low rpm's.

In any case, I would like to know the specs (number of columns, etc) on the original core (the 419500) to see what I can do next. If anyone has access to this, I would appreciate having it.
