Is it normal for a car with no overflow to dump a bit of antifreeze after a day

As usual great interesting info Slantsixdan ! Not sold on the evans fluid , your last post stating might not work with some older rads , will stick with 50/50 ,and coolant recov tank and cap from a 1974 Dart , don't think it is a pressurized system . Not 10% sure though .Oh and not to forget the distilled water , have always used that and in 40 years have never had a rad failure , and I put over 450,000 km on my cars before selling them . Of course I change all fluids every 2 years , brakes steering , rad and diff , Trans and oil more often . With the right maintenance cars last .
Thanks again for the informative post !
