You must use the correct antifreeze. All antifreezes are not compatible. Check your Owner's Manual. Our year model 2010 Ford recommends:
"Motorcraft Premium Gold Engine Coolant with Bittering Agent (yellow-colored)"
The color is just for identification, but the chemistry is specific. Most major brands have equivalents available at most auto parts stores, and maybe Wal-Mart, etc., but be sure it meets the Ford specification. The engine has aluminum components and must have the correct anti-corrosion additives.
Also, use distilled water instead of tap water if you dilute it. That way you don't introduce chlorine or other stuff which aluminum does not like.
