You can't fill your rad to the neck, the coolant expands when it gets hot and if there's no room in the rad the rad cap spring opens up and it spits out of the overflow. You might just have to much coolant in it.

But check the basics to ensure you have no oil in your coolant and vise versa.

Is it just too full? Mine runs down about an inch or more from the top.
