rust in water
I have always had pretty good luck with the water being clear of rust in my cars. I use a bit of soluble oil in them with distilled water as my choice of coolants here in sunny CA at sea level + 384 feet. Then recently I had occasion to examine the radiator water on the roadster and found it low so I added a bit and went for a drive. When I got up to freeway speed, around 55, I noticed an orange froth just below my moto-meter. Got home and checked, never saw it rusty like that. What could have made the engine rust up that fast? I drained it all and filled with vinegar and will drive it a few weeks than flush and do a soda treatment or two before filling for good. Should I be using a coolant instead of water? Been driving this car since 93 with no real rust problems before. (But then that's what the guy aid when his horse died, "Never did that before.")
