Coolant temperature sensor

So here is the story. Last week, on the way to work, my temperature gauge started rapidly climbing at a stop light. Once I got moving, it dropped to about half range. But, all the way to work it was having wild fluctuations. I thought the problem would either have to be the thermostat or the impeller. Being the easiest and cheapest thing to start with, I decided to do the thermostat first.

Fast forward to today. I have a new thermostat and orings, and finally have the time to work on it. When I get the tank off, this is what I find. Looks like the connector previously broke on the temperature sensor, and someone did a sloppy job trying to solder it back on. I am going to solder it again to get it working, but also just ordered a replacement sensor.

So here is my poll question. Since I already have the tank off, and already have a new thermostat, should I go ahead and replace the thermostat? The bike was not otherwise acting like it was overheating, so not sure if it is worth the effort.

If you already bought it, go ahead and put it in. Summers coming, I'd rather have a new one than an old one (that you do t know how old it even is)
