Hey man. I also drive a 97 pathfinder. My gauge sits at the same level as yours, never seen it go any higher. It’s my understanding that the gauge position reflects a pretty wide temperature range. I have one of those Bluetooth OBD2 scanners hooked up to a tablet I keep in the car. There’s a coolant temperature sensor on it that I use for longer drives, my coolant is usually between the high 170s and mid 190s (Fahrenheit) when the gauge is in that position. I want to say the gauge won’t move any higher until the temp is like 220 or something, but I don’t know for sure.
