They ask for distilled water to be used when mixing with the coolant concentrate. The water here comes from the Murray, salt and all, at least the distillation will reduce the salt level.
The acid wash has been pressure flushed out, granted by using Murray salted water and compressed air, I could run a soda wash through it to clear out any remaining citric acid .... but I think the salt isore of a problem than any remaining citric acid, that stuff neutralises itself as it acts on the rust scale, so my guess is it would be fairly ph balanced by now.
I could run just distilled water through it fo a while, then drop that and add the coolant and distilled water ..... worthwhile? Or over the top?
That citric acid goes in clear, it comes out very dark green, almost black, the concrete was covered in what looked like fine clay silt, a lot of it, but this was all the cooling system stainer caught, so it doesn't look like there are large rust flakes in there anyway. I'll check the water strainer/filter every few days at first, just to see if anything gets stirred up while driving
