Little advice.
For 2 bucks more u get just a full gallon of antifreeze. Take an empty milk gallon and fill that half way. Pour half the gallon of antifreeze in then the half of galon of water. With the half thing of antifreeze mix it with water and fill that up. Now u have 2 gallons of 50/50 for 10 bucks.
But yeah there's really no point to run ur car with water for a few days. Flush the dexcool out and put the good ol green stuff in there.
