normally the gauge should be in the middle.(between hot and cold) that is concider operating temp.

By hooking up a vacuum gauge could help indentify bad valve. the needle of the gauge would bounce erractically during idle.
It depends, sewing needles come in all different sizes.
I am in the process of fixing my fuel gauge problem now. I took the fuel pump out of the tank. at the top of the float arm there is a memory stick much like the sim card you install in your cell phone. it has many copper lines running through it (looks like the gas gauge) and the read needle on your float arm gives the reading of how full the tank is. the needle on the float arm seems to rock back and forth or side to side which over time pulls the needle which is spring loaded (no actual spring, but by the bend in the metal) away from the chart or sim card. you can try very very gently to put the spring back in the needle by inserting a small regular screwdriver or equivalent behind it and try and get the needle to make contact with the sim card again. if successful your fuel gauge should work properly again and you save a couple of hundred bucks.
when i first got my industrial piercing it was gauged at a 16 i would recomend this simply because the piercing needle is smaller and it is a smaller wound to heal than that of a higher gauge
why is the temperature gauge not moving on a 2007 Lincoln mkz
Defective temperature sensor or bad gauge
In any vehicle, when the radiator system is working correctly, the temperature gauge needle should be just below the half way mark when up to operating speed and temperature.
Below the middle mark. if you have not removed the battery and the needles poped past the stops. this willmove the temp gauge and place it at a higher reading. replace dash to correct this.
mostly likely something wrong with the sensor or gauge.
that depends on the thermostat. but the book calls for 190 degrees. your gage should be + or - 10
Needle in gauge should be midway between the 80 mark and the mark just above it.
A temperature gauge, that always read the maximum temperature, is usually not connected to the temperature sensor. The wire between the gauge and the sensor must be broken.
If the temperature gauge needle doesn't go back to zero when the car is shut off, it is possible that the needle is sticking. A little WD-40 or electronic spray on the gauge might fix the problem. There could also be a problem with the MAP Sensor or a Radiator Pressure sensor in the engine.

In the middle (about 195 degrees).
the normally position of needle in temperature gage is a half of gage.
