My temp gauge used to read pretty much in the middle. A while ago it started reading from below the N to the line at the bottom of the range. It also was not stable anymore sometimes it would be at the N other times all the way down at the minimum line and it would bounce around too.
Mechanic replaced thermostat he said the gauge was reading correctly and temp was a little low. Initially was acting more normally would rise to between N and O and stay there.
But about a week later noticed it is acting strange again. One day after driving about 6 mi I noticed the needle pointing at that line to the left of the N again. I stopped at a light and after a bit the needle rose back to between the N and O and stayed their for the remaining few miles to home. Then today it had warmed up to between N and O then it dropped back down to halfway between the N and that min. line.
The temp used to be stable, what would cause it to start bouncing around like this besides the thermostat that was already replaced?
