Question for the group about thermostats and temp and temperature gauge.
Assumtion here:  Not all temp gauges show the same range on the dial.  Also
I'm looking at a temp gauge in a '90 GL body, with tach.
Okay, given that.  Now, what should I expect to see on the gauge under
different conditions?  My temp gauge, under highway conditions that are
putting on a load like climbing a mountain pass, NEVER goes past a certain
point, actually just above the center of the LED.  As the systems heats up
the needle gets to that point, fan comes on and under extreme conditions the
fan will go into 'propeller mode'.
But here is what I have a question about.  In cold weather, generally 60 F
or below, the needle on the temp gauge, under normal driving conditions even
on the highway, will stay well below the LED and in 40 F weather way below.
Logically I would expect the thermostat to open and close to control the
cooling to hold the engine temp at a steady temperature.  But, assuming my
temp gauge is accurate that's not what I'm seeing.
So, what do others see, is what I'm seeing normal, or should I be putting in
a new thermostat?
BTW,  my rig has been this way for the seven plus years I've owned it.
