sounds like a chemistry problem from high school. only looking at the 7qt of coolant/water you replaced, I calc 57% coolant. based on this chart from mkiv.com, this shows your freeze & boil protection.

% Coolant Freeze Boil
20% 16 253
33% 0 256
40% -12 260
50% -34 265
70% -90 277

you can partially remove the coolant/water mixture in your radiator and replace with water to reduce the % coolant as follows per my calcs.

coolant replaced w/ water % coolant
6 qt 8%
5 qt 16%
4 qt 24%
3 qt 33%
2 qt 41%

I run at 20% coolant with a bottle of water wetter. mind you I never see any snow. :D
