B-series Radiator?

[Demsum]

I'm running a B-Series engine with my old single core radiator from my original 1.5 liter engine that came with my EG. I had no problems with heat, until I recently flushed the radiator and refilled the coolant. I noticed what may have been some mineral deposits when we flushed it. At first the radiator leaked a little and the coolant that leaked got on the radiator, causing it to burn and raise my temperature level pretty quick. Now the leak is minimal and the coolant level has been pretty steady recently, But it's still overheating at a slow pace. It seems like the more I drive it, the more this problem works itself out. Has anyone seen anything like this before? Does anyone else use a single core radiator on a B-Series Motor? Let me know.

Nevermind, I just bought a new radiator, cap, and thermostat.
