So I've done everything that I can think of to cure my overheating problem to no avail. I started with a coolant system clean and flush then replaced the thermostat, put an electric fan on it, replaced the water pump, the coolant temperature sensor, and put a new two row radiator in it. Everytime I've been sure to bleed the air out of the system. There is no oil in the coolant and no coolant in the oil. There are no bubbles in the radiator. I'm out of ideas here.
