ne isn't a word.

How much pressure did you apply, and how far did it drop. Pressure can't hold forever. Afterall, the radiator is designed with a controlled leak. It should hold fairly steady. With a leak that is obvious, the pressure tester will drop pressure quickly. Like right now. Check the cap itself, if your tester is capable.
