Bitsa cooling system capacity ?

Its bitsa this and bitsa that… a '25 block with a Waukesha Ricardo head hooked up to a 1915 Brass-Works radiator.
Can any one give me an approximation as to the capacity the cooling system is likely to have.
I’m trying to work out dilution percentages.
Thanks & Cheers,

Wouldn’t know, but what I would do to find out is fill it with water and drain it into buckets and measure what you drain out.


Where I live a gallon of 100% Preston’s ethylene glycol is mixed with the rest of capacity of tap water. This is about 2:1 since brass radiator T’s hold about 3 gallons.

Thanks again Royce,
