I suspect you may have damaged one of the connectors at the condenser. That is the think in front of the radiator that actually looks like another radiator. That is my first suspect for a leak. The condenser and condenser block are attached to the radiator. Although you don't have to drain the Freon or take any of it apart, something is most likely leaking from the work.
Did you take apart the condenser?
