Like Jeff said, may not have a bad radiator.
If it is coming out near the valve cover, it could be a blown head gasket (cheap), cracked head (little more expensive), a heater hose? Where exactly is it coming from? Front, back, side, top of the head, bottom? Pics help greatly. Even a picture of you pointing at where it came from.
Betcha' wish your girlfriend was as dirty as my Jeep!
Zombies hate fast food.
Hang on! This is gunna' be a thrill ride of geriatric proportion!
