Default Coolant reading sits at 50?

Coolant meter sits closer to 50 barely see it budge and if it does it doesn't move much at all Is this normal? Bad temp sensor? This pic is just an example of what the gauge looks like, if you look over on the l

eft side of the dash you'll see the different levels.

The AJ6/16 engine cooling system thermostats fail OPEN.

Maybe replace the T-Mostat and report back? (is the heater putting out hot air?)

Is your oil pressure gauge slow to respond, like a 5 second time delay in both increasing in pressure with engine revs and the decrease in pressure when back down to idle?
Mine is with the digital dashboard.
As for the temp, mine sits 1 to 2 notches either below or above the 90 mark. At idle with the AC on and a hot day it sits 1 to 2 notches above the 90 mark and the electric aux fan will be running.
Driving along with the good airflow its below the 90 mark.
Also the snow, winter panels at the back of the electric aux fan have been removed.
