The guage on the dash uses the ONE wire sensor... This is located in the block near the drivers side. Eric First check to see if you have coolant in the radiator. If there is no coolant you will not get any reading from the temperature sensor. If there is coolant then change the temperature sensor.
The needle on the coolant gauge should typically be in the middle of the gauge's range when the engine is at normal operating temperature. If the needle is in the blue zone, it indicates the engine is too cold, while a needle in the red zone signals overheating, which can lead to engine damage. It's important to monitor the gauge regularly and address any abnormalities promptly.
why is the temperature gauge not moving on a 2007 Lincoln mkz
engine coolant
Defective temperature sensor or bad gauge
Bad gauge or defective coolant temperature sensor
water temperature. 180-220 degrees
Low Coolant or faulty gauge
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
The temperature sender (the sensor that sends the temperature signal to the gauge) has to be immersed in coolant in order to correctly read the temperature. If the coolant is so low that it leaves the sender high and dry, the temperature shown on the gauge will not be a true reading. if the sensor is not immersed in the coolant, there a big chance it wont read at all...
The needle stock behind the stopper on a temperature gauge typically indicates the maximum temperature reached by the gauge, serving as a visual reference for monitoring temperature changes. When the temperature exceeds a certain level, the needle moves and can become stuck due to thermal expansion or a malfunction. To reset or adjust the gauge, it may be necessary to carefully manipulate the stopper or recalibrate the gauge according to the manufacturer's instructions. Regular maintenance can prevent this issue and ensure accurate temperature readings.
seriously? it tells you what temperature you engine coolant/antifreeze is. that is how your gauge on the dash knows what your temperature is at.
mostly likely something wrong with the sensor or gauge.
