There have been isolated reports on this Forum of catastrophic coolant loss caused by failure of the plastic part of the radiator.
It seems that some of the radiators fitted by MMC in the 2008-2010 period may not be robust enough.
The answer is probably to fit an all aluminium radiator from MulFab.
MulFab I suspect that if your radiator is weeping at this point it is going to fail.....sooner than later.
