Have been trying to research the title code. While the common wisdom is a failed open thermostat I’d like to verify that the thermostat is the problem. I have an OBDII reader which tells me the coolant reaches 180-190F range. What I don’t know and haven’t been able to find is what the normal running coolant temp should be. Anyone have an idea of the “normal” temp range for a 2015 SC AWD XF?

thanks
Dennis
