That is the way it is designed. When the key is turned on then it reads correctly.
why is the temperature gauge not moving on a 2007 Lincoln mkz
Defective temperature sensor or bad gauge
mostly likely something wrong with the sensor or gauge.
What are you talking about? My temperature gauge works fine. Though, if it wasn't I would check the temperature sending unit.
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.
the gauge is the measurement of how big around the stud or needle is
The 21 gauge is a smaller needle.
Gauge is the term that indicates the diameter of the needle. Most commonly the needles that are used for medical purposed range from 7 Gauge to 33 Gauge, according to the Stubs scale. 7 Gauge needle will have the largest diameter while as the number increase, the diameter decreases. Therefore the 33 Gauge needle has the smallest diameter. So a 26 Gauge needle will have a smaller diameter than that of the 18 Gauge needle.
Yes, the larger the gauge the smaller the needle size.
