Eethylene Glycol
It came from the factory with 50 % antifreeze / 50 % water mixture ( do not exceed 60 % antifreeze or drop below 40 % antifreeze - engine damage may occur )
According to Ford a 50 / 50 mix of antifreeze and distilled water is required year round because the antifreeze also provides corrosion protection ( do not drop below 40 % antifreeze or exceed 60 % antifreeze ) Also , the corrosion protection additives in the antifreeze do " wear out "
Yes

They come from the factory with a 50 / 50 mix of anti-freeze and preferably distilled water . Do not exceed 60 % antifreeze or drop below 40 % antifreeze
Not if the temperature will fall below freezing.
Fords come from the factory with a 50 / 50 mix of distilled water and the correct type of antifreeze for the vehicle Ford states not to exceed 60 % antifreeze ( colder climates ) and not to drop below 40 % antifreeze for the corrosion protection ( warmer climates )
Generally, heating from below, which creates mixing.
When the outside temperature dropped below 32 degrees F.
A mix of 50% clean water and 50% straight antifreeze is good for most areas. If you live where the temp goes below -30 degrees F, a mix of 25% clean water and 75% straight antifreeze would be better.
A mixture of 50% water and 50% antifreeze will transfer heat better than straight antifreeze and still protect the system from freezing up to at least 34 degrees below zero F.
