Hey I have kind of a weird question. I was looking over my fluids in my car today and saw that the coolant was low so I went to buy some and filled it up. I filled it all the way to the top (i'm sure I wasn't suppose to do that) and didn't spill any. After filling it I saw some come out of the bottom of the tank. Not a lot just maybe 2 tablespoons. After that it was fine. No more leaking. It never done that before and hasn't done that again so I was wondering if that's normal or something I need to get checked. I don't know much about cars, so sorry if this is a dumb question.
