How long are the tubes, and how many disks are there on a 4X4 Model A radiator?
Ref Chapter 9, page 18 of 26 in "Pate's Early Ford Automobile Encyclopedia" -- tubes were 27.33 inches long.
There are a lot of other details about the individual fins on the tubes etc. on pages near that. Also a discussion that the do not have a specific cut over date. And he has a discussion on the flow of the water etc. through the ends of the radiator etc.
I would encourage any owner of a 1903-1909 Ford or someone who wants additional details about them to obtain a copy of Carl's excellent book. They are available from the vendors, the club store, and the author at: http://www.earlyfordcars.info/
I would also suggest they join the 1903-1909 Early Ford Registry at: http://www.earlyfordregistry.com/ -- they are also a chapter of the Model T Ford Club of America.
From memory -- not as good as it once was -- I'm 80% sure that someone has reproduced an accurate reproduction of the original tubes with the individual disks on them. Brass works would be a likely choice for that, but it may have been someone else?
And of course any photos you can take while you have it apart would be appreciated.

A 4-wheel drive radiator? Wow, that's gotta be something to see!!
There are 60 fins per tube, tube length is 20.5". Distance between radiator mounting holes is 24 1/8. These measurements are from an original radiator and there are many repo radiators out there , so your dimensions may vary!
Thanks Hap, that is good information.
That's great info Kim, thanks!
Tom, the rube length on the repo radiators I made was also 20.5" so I'm pretty sure that's correct. I have complete side castings for the 4x4 radiators if you need pieces.
These are the tubes I made, there about 58 fins per tube
Kim & Tom,
Bottom Line Up Front: I apologize for my oops! My bad I didnt read what was printed correctly in Carls book he also the single tube length as 20.5 inches.
Thank you for the additional details. I was going to send Carl Pate a note that he might have a type-o there in his book. Then I looked closer and noticed he had the length not as 27.33 but 27.33 (i.e. feet). So then I looked at his chart again. He is comparing how the total length of the cooling tubes increased over the years. I.e. the 1903 had 4 rows high by 4 rows deep of tubes for a total of 16 tubes. Total tube length is shown as 328=27.33 . If we divide the 328 by 16 tubes it comes out to 20.5 inches for each tube.
For the 1904 AC it has 18 tubes 6 x 3 for 369 total length divided by 18 also equals the 20.5 inches for each tube.
And the chart goes all the way up to the 1906 F showing the different radiators how many rows high by depth and total combined length of all the tubes. For the 1906 F the total length of the tubes combined had increased to 861 inches. A lot more length and cooling area (they went to larger fins also) than what they started with in 1903.
I need to remember not to try and read charts early in the morning! (Yes, I did it again just now but I had a good gouge on what the correct answer really was so it was much easier to see how to read the chart.)
