If the tank truely separates the regular cooling system and the s/c cooling system then there shouldn't be ANY coolant in that tank(water cools better than coolant/antifreeze). Coolant is for keeping the water from freezing. On top of running 100% water in the tank, I believe, there should be a drain **** of some sort in the bottom to drain out enough water to be replaced with ice when necessary. Again all my thoughts and they may be horribly incorrect..........read at your own disgression.
Actually - you are right on the money - in the last photo - you will see that I have added a new header/surge tank for the radiator coolant.
According to the OEM maintenance manual and a great write up by stewartcomponents.com, pure (distilled) water cools better then anything else, better than water wetter etc... So I refilled my engine coolant with 1/4 anti-freeze and 3/4 distilled water.
I used 1/2 anti-freeze and 1/2 distilled water for the IC coolant - WHY??
If I am adding dry ice - I don't want the water in the IC tank to freeze. Dry Ice, when melting, has CO2 that needs to escape but won't add water volume to the tank. - Also in the last picture you will see a small 1/4" bung, this will allow for the CO2 to escape while not blowing up the tank. Remember your JR. High science class when you added dry ice and water into the metal film container? Well we had metal ones back in the old days, some kids used them for something else...
Anyway - this same bung could be routed to a plastic catch tank if you were to add wet ice to keep you from dripping on the track - or - I could add one more bung to the bottom the tank for a valve to drain the extra water so you could add more ice between heats...
Keep the great ideas coming..
Here is a picture of the inside - I added a baffle to keep ice from clogging the outlet bung.
