hey guys, ever since I got the rig, I noticed the engine temp arrow is always a little past the center, I checked operating temps, and it runs at 118F all the time, already replaced thermostat, water pump, new expansion tank, I did NOT however replace the little sensor at the bottom of the expansion tank, could that be my issue or is there something bigger going on?

Car runs great other then that, but it just bugs me that it runs that hot
