That was what I was kind of thinking it might be, but after thinking about it for a while I think it might have to do with the radiator cap. Since I bought the car I have never taken off the cap until yesterday, the levels of both the radiator and the overflow tank became normal after I took off and replaced the radiator cap. So what im thinking is the spring inside the cap might have been stuck or something and by taking it off it somehow fixed it. Oh and the low coolant light hasn't come back on either.
The other possibility is the fact that my dad touched my car, he seems to have magic car repair abilities where he can fix a car just by touching it. Here's an example, on time I was having ignition problems with my 85 ramcharger. I called him up and with the first try it started right up. It ran fine the whole time he was there sitting in the drivers seat, he then left and about a minute later it died and I couldn't get it to start again. The amount of times that he has done this with not just my car by others as well is astounding.
