Then you are fine. If you are really concerned, I'd go grab a 180* thermostat from the part store. They come in three temps, 195*, 180*, and 160*. I wouldn't go with the 160* ever but that is me, I run a 195* in my truck and it never surpasses that unless its like 100*+ sitting in dead stop traffic. As I said, pull the dipstick out and TASTE it. If you are running antifreeze, you will IMMEDIATELY taste bitter nastiness. Like super bitter.
