Water can transfer much more heat than coolant. More water and less
coolant.
You obviously loose some of the safety margin if you start to overheat since
the boiling point will be lower.
You loose some of the lubrication and additives.
You may need to change the coolant in order to withstand the temperatures in
your area during the winter.
