What happens when you overfill car with antifreeze?

I don't think you can actually overfill a car with antifreeze. There is an overflow chamber that prevents this. Perhaps this overflow can be overfilled but in that case the worst thing that can happen is the little plastic cover pops off and you get some excess antifreeze on the ground. It might also depend on the car. when car gets hot it will push coolant to reservoir (expansion) and when cold, into radiator. this is the function of the rad. cap....if u overfill reservoir it will only leak out of fill cap to the grd
