Something to think about: You have fuel injection; unless you reprogram the computer to think less than stock is good, I'd think you will be running like your coolant temp sensor is on the fritz.
Agreed, plus coolant temp showing lower than other values will trip error for coolant temperature sensor out of range or not plausible. I would say get a good Stant t-stat it only has one tiny vent hole and no rubber flapper unlike the factory one with the whole perimeter of the diaphragm perforated and the rubber umbrella.
Modern engines need higher coolant temps
