Radiator repair

[Radek]

The leak is in the bond between the plastic top and the aluminum core.  The 
core is held to the plastic end by  U-shaped notches (for the lack of a 
better term) which I managed to set a little deeper with a punch. This has 
slowed down the leak.  Has anyone managed to separate the core from the top 
and bottom ends without destroying something?
