    Hi! I have a 2012 Durango with a 3.6. I keep getting code p0128 coolant code. What to try? Theromstat or coolant sensor? Thanks in advance!

    The heater and temp gauge works OK? I would try the PCM flash that is addressed in TSB # 18-110-16. It fixes a slew of false fault code sets including P0128.
    It should be covered under your 8/80 extended federal emissions warranty:
