    everyone, I been having high engine temperature issues or maybe it is normal? 2nd Gen Prius engine temperature will reach to 230-238F after 30 minutes of highway drive (outside temperature 95F) and AC is off and I use Torque pro to monitor coolant temp. And no, the engine overheating logo has no been on MFD at almost 240F
    Things I done to the car: bleed coolant system followed all the YouTube videos( jump the coolant pump relay, open bleeder etc) Removed thermostat for testing purposes, new radiator cap.

    Is the Torque instrument calibrated correctly?
    Have you used other measuring instruments for comparison?
    A faulty measuring instrument can show the temperature on the surface of Mars and inside a volcano vent at the same time.
