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

Good Morning again Joe...I did neglect to mention that we also added a fan shroud and a higher CFM Fan to our system. I really do not believe that the larger radiator is your problem. All of your comments mirror our experience and the distributor and vacuum advance were the final difference.

I am also active with Model A Fords and we routinely put larger radiators and fan shrouds on them to run them in the desert. If everything else is right, it always works.

We did also change from a Autolite distributor to a Delco distributor as the advance is internal in the Delco and with the Autolite, the entire distributor has to turn and can be impaired by the plug wires.

I have also read that some cars begin with the timing a little advanced from the 6 degrees that the book calls for with modern fuels...I am no expert, I am just relating what happened with our Packard.

Deluxe Canuck, up in Canada also added a shroud to his 1949 and reported that his cooled down after the shroud was added.

One question...What temperature is the return water coming into the radiator and what is the temperature of the output water returning to the radiator? Ernie
