JEEP was leaking anti-freeze some time ago. Took it in to the shop, and they replaced the radiator, and heater core hoses. Still leaked. Took it back, and they replaced one of the freeze plugs. Still leaked, and they replaced all the freeze plugs. Still leaks. Took it back today. I put about a half gallon of anti-freeze in before I left. Got about a mile outside of town, looked in my rear view mirror, and couldn't even see the truck that was behind me for the smoke/steam. Wasn't sure what it was until I pulled over and seen anti-freeze everywhere. Dumbass here forgot to put the radiator cap back on. Duh. Luckily, the cap got caught between the bumper and frame, and was still there. Good morning to me.
