Yesterday I bought a heater core from a used parts dealer but Im afraid its leaking. I run it with my submersive pump connected to the radiator and the other hose expelling the water out of the radiator in the bathroom sink. Fresh water comming to the pump from the sink. No water block was connected. After leaving the system for 10-15 minutes I realised a small wetness on the radiator surface, not really drops just a small glancing of wetness, but evident when you touch with a finger. Actually i could feel it on all radiator surface.
This is my first radiator (core) so i really dont know what to do. Before i return it to the dealer can I be sure its leaking or not?
Any suggestion highly appreciated.

Thanks in advance!
