ok so i was driving home from work sunday night, and i was at a red light and all the sudden i see smoke out of the corner of my eye, and kinda smell radiator fluid. so i think to myself ahh crap something is wrong. so i get home and as soon as i park it starts smoking bad, so i get out and pop the hood and the smoke starts rising out and i hear a loud hissing noise, and it seems like the noise was coming from the back of the motor but i couldnt really see because it was dark, and now that i think about it the smoke seamed more like steam. any one think they know what it could be? i talked to a friend of mine who knows a lot about mustangs and he is thinking (well hoping) its a heater hose, or (not hoping for this one) a head gasket..could someone give me their 2 cents? thanks
