how many gallons of antifreeze does the 1912 ford radiator take? I use the pre-mixed kind. Thank you.

I believe the cooling system holds about three gallons, so about $12 worth of water when you buy it 50/50 premixed...

(From one of Hap's posts) Dykes Motor Manual shares: 12 quarts for the 1917-22 cars and 11 quarts for the earlier models.

That's for the whole cooling system.

Is that before or after burping out what it doesn't need after starting and running up to operating temperature? No need to waste expensive antifreeze filling up to the top if it's just going to rid itself of all it doesn't need. Jim Patrick

If you get it on your radiator, good luck trying to get the stains off. They don't!

I searched online and found this site:

http://hellafunctional.com/?p=629

It showed the following three charts, showing how the freezing point, boiling point, and heat capacity (mixture efficiency as a coolant) varies with antifreeze percentage.

freeze

boil

heat

On my T, I put in one gallon of antifreeze and filled the rest of the system with water, giving a little over a 33% antifreeze mix. According to the charts, the resulting freezing point is -4 deg F, the boiling point is around 220 deg F, and the coolant has 93% of the heat capacity of pure water. This will work fine for me (I live in the St. Louis area and I have a heated garage). You might choose a different mix based on your circumstances.

What percentage do you need for effective anti-rust?

Mark,
I agree with you and think many folks use a 50/50 mix when it may not be in their best interest.

The other thing that may enter into the picture is the viscosity of the mix and is likely even more important with a non-pumped thermosyphen system. It makes sense to use the least amount of mix for your location and still get the freeze protection and rust protection.

The more antifreeze you add, the less efficient it is as a heat transfer liquid and the slower it circulates. It is a double edged sword.

Here is the viscosity chart based on the mix:

The website I got the charts from said that as little as 10% anti-freeze is plenty for corrosion protection, but I find it convenient to just dump the whole gallon in and fill the rest with water.
