If you have the 3.4L V6 it's probably a blown head gasket. They're notorious for that! The sensor that popped out of the radiator is the low coolant level sensor. There's two bleeder valves on this engine. One at the thermostat housing and another on the metal heater hose pipe. Be sure you have both open when bleeding the system. HTH. -Jim
