Ok, yesterday, my car overheated for an unknown reason... I bought 2 gallons of antifreeze and put it in the reservoir, and the car cooled down and was fine. After driving another 30 miles, the car overheated again. I looked under the car, and the antifreeze was pouring out from the excess tube, since the antifreeze started boiling... Anyway, I finally got the car home, watching my temps, and making sure it didn't go over 230F. At home, I poured a gallon of water into the reservoir to try to find out where the leak was. I checked the upper and lower radiator hoses, and the leak isn't coming from them. The leak appears to be coming from somewhere in the middle of the car, and drips out of the bottom from an underbody pan or something. After placing the water in the reservoir, there was no leak, until I started the car and then I could see the water leaking from the places described above. I don't think its a blown head gasket, but I'm not sure what it is. The car still runs fine, and still has its full power and speed. Please help me, and tell me what could be wrong! Is it maybe my water pump or heater core? Also, if its the heater core, how much does that cost to get replaced in a shop, and how much would it be if I could do it myself? I'm sort of leaning towards the water pump, but I'm not sure....
