Today on Briley Parkway, the kia's engine died. Came to a complete stop on the off-ramp. I opened the hood, checked the oil. Its good, not low, Checked the resivor for the radiator, it was full, opened the radiator cap ( after it kinda cooled down ) All belts are on, can't see the timing belt cause its covered. One thing I did notice before it died. I had steam coming in from the vents inside the cab. The gas preasure started to decrease. Once I came to a complete stop, I pop'd the hood, steam was coming from the engine. I didn't see any bubbling to show signs of a busted head. I'm not sure what it is. Any help would be greatly appreciated.
