Default Re: Rusty Coolant

I cleaned up and painted an engine this summer for display. While I was high pressure washing it with the head off I held the nozzle in one of the water jackets. I didn't care if water went past the pistons. Rust came out for at least 20 minutes in chunks. Flushed back and forth it kept coming. I really don't think a short flush with a garden hose gets all the crud out.
