Need Radiator Help Quick

this morning on the way to work the jeep overheated, tried putting coolant in the bottle, but its running out a little fitting that is located on the side of the radiator, donw at the bottom, by the battery kinda, the coolant just runs out on the road, apparently, it blew out of there when it overheated, cuz the bumper under the headlight had coolant and the wheel well was really wer from all the steam or something, is the rad. shot or just that piece or what???

ok with a little searching on the net, looks like a radiator drain cock, but why is it pouring out, i guess im gonna try to call the stealership and talk to a mechanic or something

Your description points to the draincock. Have you tried turning it to see if it's just open? If it overheated, though, it may have ruptured where the drain is fitted into the plastic tank. If that's the case, with a '90 you're overdue for a new radiator anyway.
