Just what it says, I have rusty coolant. I have tried the vinegar trick, I have flushed, flushed again... Vinegar actually caused leaks from my experience. My Dad always ran water because he said antifreeze creeps in places water can’t (smaller molecules).

The engine is only a few years old on a rebuild where it was extensively cleaned out. The radiator was replaced after the vinegar experiment and subsequent leaks. But it’s still rusty.
What do you do to stop the rust? Is there an additive? Do I run antifreeze instead?
