    Default Stuff in 3 year old coolant.

    Checked my coolant as it was starting to drop below min level. There's a ring of sandy material around the inside of my reservoir. What could have caused this?

    It's probably from casting the engine block. I had it in mine when I changed the water pump several weeks ago.

    I've read on other forums that it's a chemical formed innthe coolant when it gets exposed to high temps for too long.
