Does anyone know what pressure rad shops test heater cores at?
I have one out, and although it has a little bit of green around the pipes it holds 16-17 PSI for hours. I've tested it dry and tested it filled with water, same results. I adapted the pump and hose from my cooling system pressure tester to a T fitting with two hoses on it for the core tubes.
Anyone who has tried to find a good replacement for a Beaumont heater core knows why it's so important to have a good original core. The replacements are small and don't fit right.
I tested mine at 15lbs for the 63, not sure now where I got that number but it works fine. I usually over check for a spec like this.

As long as it holds more pressure than the rad cap, I think you are good.

If I recall the test pressure was always 3 psi higher than the radiator operating pressure. So a 15 psi system would be tested at 18 psi. This was for testing the radiator only, in a test tank. I would think your heater core is okay at the pressure shown in your picture.

I remember a neighbour pressure testing his heater core (in about 1976). Hooked it up direct to the garden hose. The core expanded like an accordion. Grew by about 4 inches.
The good news? It didn't leak....

I had one repaired about 2 years ago (not recored, the new cores usually aren't the quality the original cores are) and I think it was a bit under $200.

Did you reverse flush the core with a chemical?
