I was driving my '94 SC around today, and all of a sudden the car got very hot, so I pulled over. I made sure that my face was right next to the cap whenever I took it off and the radiator didn't have any water in it. I let it cool down and filled it up with water. Whenever I got home, there was an ancient gurgling in the overflow tank.
I immediately jumped to HGs as a problem, so I dug into it. Once I got over to the radiator drain plug, I realized that the head of it had broken off. The threads are still in the radiator and I can see wet spots, with a bit of corrosion around it. I don't want to replace headgaskets, if it's an easier problem, so I'm checking here.
I'm just wanting to verify that I'm right. If the drain plug was leaking, it would bleed pressure out of the coolant system and wouldn't create bubbling in the overflow tank. If the overflow tank gurgles it means there is more positive pressure in the coolant system; therefore, the radiator cap will open to bleed the pressure off.
I'm pretty sure I'm answering my own questions. What else do you guys suspect?
