Recently I replaced the electric fan motor on my 56 Customline and because it was mounted in a shroud and hard to get to, I just decided to pull the radiator and flush the entire cooling system. When that process is done, you are left with straight water in the block unless you drain that too which I didn't do. The shop manual says the capacity of a 292 is 19 quarts, but I think the radiator core holds only about 10, so then the block holds about 9? It's a little confusing to me when adding the fresh anti-freeze and trying to get the correct 50/50 mix.
