i have a 90 honda accord and this morning i saw some steam coming out from under the hood. i looked and sure enough, there was a small split along the top of my radiator that had anti freeze bubbling out. what would cause this? i just redid the head a couple of weeks ago--is it possible that i screwed something up while doing this? maybe i didnt get all the air out? im just trying to figure this out before i replace it so i dont have the same hting happen again.
