My car started overheating yesterday and went all the way into the red on the meter. My radiator hose came undone and was steaming from the hood. I checked all and noticed I have no water/coolant in the backup, low oil, and no water in the radiator what so ever. I noticed there is a redish water on the drive side floorboard. After adding water to the radiator, I noticed the water was more visible on the floorboard. I haven't tried to start the car or drive it since. What could be the reason for it overheating after adding water, oil and such? And where could the water be coming from??
