change coolant

Is there any horrible consequences to running 100% coolant fluid, and not mix it with distilled water?

Yes there are. For one thing, antifreeze will leak in places where plain water wont. The higher the concentration of antifreez, the more likely you could have a leak somwhere.

BTW, I don't know of any dealer or independant garage that actally uses distilled water when replacing antifreez so, the earth will still be in it's orbit if you use clean, plain tap water.

Uses distilled water, even Culligan's filtered water at times, but getting away from mixing full strength antifreeze and using only premixed now because it's easier.

There is no horrible consequence for not adding distilled water to 50% of mix. Water is a better transfer medium for heat energy. Anti-freeze is exactly that, anti-freeze. In winter water will freeze at 32 deg F, anti-freeze prevents freezing well below 0 deg. Running only anti-freeze will reduce the efficiency of your cooling system, especially during summer, because of a lower boiling point.
