Coolant Leakage after replacing radiator

[megapat]

Hi all,

Last week, my girl friend drove my (1998) tiptronic boxster at nite and hit on a huge stone accidentally.... right bumper got slightly scratched and coolant has been leaking from the bottom right...

So I managed to drive the car home ... replaced the damaged radiator.. no more leakage on the front. I kind of followed the instructions as mentioned by pellican guide in burping the air in the system.

However, once my car has been warmed up , both the radiator manage to turn on now... the back of the car start leaking some coolant on to the floor... And im so suspicious... coz i have replaced the radiator.... and its only the front part that got hit.... why is there leakage at the back..

Could anyone please advice? Is there a hole somewhere near the engine bay to leak coolant out if there is an overflow or over pressure of air? Its making me very headache!! Thank you in advance if anyone could help !!!
