There are no leaks in the coolant hoses anywhere in the engine bay, or anywhere else. I am just wondering if the latter is tied to the former. Any ideas?
Check closer for leaks. If you are losing fluid that quickly you MUST have a leak somewhere.
The rust points to a radiator problem. Maybe you have a small hole in it somewhere. It take a closer look at it. If all else fails, drain out all the fluid and pressure test it.
