Hi I have the car listed above 2LT (V6 automatic). I have been having intermittent overheating issues. I will be driving normally with an average running temperature of about 210* but suddenly my temperature will spike sometimes to ~260* then, if not directly bury itself in the red. I get a warning on my dash saying "high coolant temperature idle engine" before getting "engine overheating stop engine". This has happened about five times. I have only received the "stop engine" message twice. all five times I have received "idle engine" warning. It had been in weather that ranged from overcast and about 70* to sunny and about 85*. It occurred while i was driving in both regular city/urban/suburban environments as well as highway driving.
