you shouldnt have to put any in unless there is a leak

 

no you dont use water, unless an emergency. You shouldnt add anything to it, it doesn't get eatin unless theres a leak. You change it whenever the manfacture recomends, which ever the mileage becasue itll become more acidic as the antifreeze gets older.
