 because there's no cap on the radiator. It's circulating, and it has an air release at the top of it that goes into that coolant reservoir where the cap actually is that you're filling. So it's bleeding the system, self-bleeding on its own. So if you've driven it, it's going to be good and clear now, so you should be fine. Sure. I warmed it up about four times just until I got the hoses warmed.
