Strange, I can't get an answer through Google on this. Help.
All questions and answers about cooling system flushing seem to be aimed at descaling for maximum cooling efficiency. Our engines run at about 25% horsepower in our normal cruise. The heat exchanger I just took off had about half its RW tubes plugged an I never saw any temp rise even when running WOT to blow out the exhaust.
Our port engine ran for about a week with salt water instead of anti-freeze for coolant. I've filled and drained it a half dozen times with fresh water. My only concern at this point is getting rid of any salt left in it.
What, if anything, should I flush it with before re-filling with anti-freeze? We'll have a brand new heat exchanger so no worry about de-scaling that.
