When you say "overflowing" where do you mean it is flowing from?
One possibility if it is overflowing from the Plastic Reservoir is simply that if you try to keep THAT full it will ALWAYS overflow.
The coolant expands when it gets hot and so if the system is topped off all the way instead of to the "MAX FILL" line, there is no place for the fluid to go as it heats up... so the excess coolant flows out the drain tube. Likely this is not your issue, but it IS a common mistake for people to fill it completely and then wonder why the fluid keeps overflowing and the reservoir doesn't stay full... it NEVER will as explained above.

@chisantos what year is your Hyundai? Does it overheat? Any other symptoms beside the overflowing?
