I got home from school yesterday and a kid I had with me said, "Pop your hood, there's steam coming out from under it and I smell coolant." I popped the hood and there was steam coming from the back of the engine. I let it cool down, filled up the coolant in the reservoir and the radiator. I drove it later and when I came home the same steam was coming from the same spot.

It's hard to see back there, but does anyone have any ideas what this could be? I really love this little vehicle and I hate to see it go, but if it has a cracked block or head I don't think I can afford to fix it.
