A couple weeks ago a rock took out my windshield. Got that taken care of and then yesterday I got to work and noticed that my radiator was taking a pee all over the car in front of me. Upon further inspection there was a pebble, no bigger than my thumb, wedged between the radiator and the lower part of the core support. Today I removed the radiator and smoke checked it to make sure that was the only leak. It wasn't, turns out my cap is a POS. I believe it is the original rad, no rebuild tag or anything. So, lacking a stick of brazing rod I cleaned it up, soldered the damaged tube, pressure tested, and then straightened some fins. I put a coat of paint and will put it back in tomorrow after I paint some stuff that I can't get to with the radiator in the truck. Part number My repair is next to the big blob of solder. Got kind of heavy handed with the wire brush Pre fin work After straightening fins. Not pretty but opened up the airflow. I could have spent two more hours on it but got no time tonight.
From what I've read Extra Cooling meant they put antifreeze coolant in - otherwise standard cooling they simply put in water with no antifreeze coolant.

Ford put anti-freeze in everything. Can you imagine new vehicles sitting on lots during the winter with no anti-freeze?
I did read it in a Ford publication. I laughed to myself at the time thinking "was that all it was".
Here's a pic of the 1966 Salesmans Facts Book. Note how for F250 4WD it says
Radiator, Extra Cooling (V-8 only)
But my own 1966 F250 4WD with 300-6 has the invoice with Extra Cooling Radiator on it. So, perhaps the left hand didn't always know know what the right hand was doing. Notice this is all Ford documentation.
Thanks ND, how to tell the difference between standard and extra cooling? My core goes all the way across the tanks. Thanks.
As ND said it is the same radiator for both Standard and Extra Cooling. So, what EXACTLY is an "EXTRA Cool Radiator"? Both of my 4WD trucks show it on their invoices but it is the same radiator in the MPC for Standard and Extra Cooling for both. So if the radiators are the same, the core support is the same, the hoses are the same and the fan blade is the same that doesn't leave much.
I'll keep digging. I have a lot of Ford paperwork here and I have read about it. Finding what I read will be the tricky part for me.
My experience from building new radiator cores in my younger days would be the spacing between the tubes. Higher capacity equals same exterior dimensions but the fins are closer together. Think shorter Christmas trees. This allows for more tubes which increases the volume of coolant needed to fill the system. Maybe Chad and ND can lookup the specs on system volume for us.

What if with extra cool you got ethylene glycol anti freeze and with standard cool you got methanol antifreeze? I remember methanol antifreeze being dirt cheap compared to glycol antifreeze in the 60's and 70's.

No specs on system volume that I've ever seen. If the radiators were the same part number then they were the same radiator in design. Changes to cores would mean something is different and so that would get a different part number so humans could distinguish them from each other.

That might have been it. I just know it was something to do with antifreeze was all it was.
If you run alot of dirt roads,(I do) i go to a house screen shop and have them build me framed screen that fits in front of my rad. it wont stop big rocks but keeps a lot of chit out out of my rad. My Ford New Holland came with one,thats where I got the idea.
