I recently replaced my radiator. I added water to the new radiator and ran the engine for about 5 minutes then drained the radiator and did this several times. But each time only about 1 gallon drains out with some old fluid. Is this normal? Do I just continue to fill and drain the radiator or is there something I'm missing?
