Mine must not be original, as I have no writing on top side of housing.
I replaced it at around 140,000 miles. It did not fail, but I thought it was running a little too cool, maybe 160. So I changed it and the temps went up a few degrees, maybe to 165. Both were 80 thermostats. So the old OE thermostat probably was still okay.
