Hello, My name is Chuck and I'm new to the forum, I've recently had a freeze plug blow out completely while driving, I hade to pull over and get a tow home, after replacing the freeze plug I did a complete fluid change, anti freeze (obviously) and oil change, no sign of anti freeze in the oil, when I was finished the Jeep would not start, it wanted to but just couldn't, so I tested everything from the coil to spark and replaced the crank sensor @ $78, finally the jeep started but only when I had the gas peddle to the floor for a period of time, rough idle, rough start and shaky, now the temp guage is way hot but the water is bubbling out of the over flow tank ice cold, can also hear the water in the radiator bubbling and moving, no heat at all but again the jeep is hot according to the temp guage, I fear it's a head gasket but wanted to see some other opinions and maybe theirs something else I can do to confirm it's what I think it is, thanks in advance for your time! Chuck.
