I'm working on a nc700 that has had wrong (green, silicated) coolant in there for most of its life. The cooling system internals are now coated with a white powdery substance similar to chalk. At its worst, white flakes were visible circulating in the radiator, I got those out after a few flushes. I can remove the white scale with a scotchbrite or a metal brush, but obviously brushes can't reach into the engine's internal passageways, so I am looking for a chemical solution here.
How do I get rid of this coating?
Steps already taken:
-Multiple commercial radiator flushes
-Multiple distilled water flushes
-Cooling system disassembled and inspected
-One test piece has been targeted for trying different cleaning methods - overnight vinegar soaking made no difference, and I'm now trying a CLR soak with results TBC.
