Temperature gauge keeps going up and down?
Temperature gauge reads signals off the coolant temperature sensor. It can also point to a faulty thermostat. If your car runs rough in cold, idles rough and uses up more fuel then coolant temperature sensor is your problem. They are normaly a cheap and easy diy to do.
Why would the temperature gauge read cold when the antifreeze is low?
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...
What does it mean when the temperature gauge keeps going from cold to hot then back to cold?
Could be low on coolant or a sticky thermostat.
Why does the temperature gauge fluctuate in cold weather and heat comes on and off?
Check coolant level Could be thermostat opening and closing due to engine coolant temperature flutuation
Temp gauge reads cold no hot air 2002 f-150?
If your coolant level is fine , it sounds like your thermostat is sticking open
Why would a 2001 Honda civic temperature gauge is moving from cold to hot?
Probably low coolant or a faulty thermostat
Would the temperature sensor cause the coolant temperature dial to always stay in the middle even with the engine cold and where is it located on a 1996 Mitsubishi Galant?
Unplug the coolant temp sensor and check what the gauge says...If it falls to cold, then the sensor is at fault. If it stays, then the gauge is either faulty or the contact points on the back of the gauges need to be cleaned...

What could cause the AC to quit putting out cold air and the temperature gauge to rise?
Hey Ken==Check the coolant in the radiator WHEN THE ENGINE IS COLD. Sometimes the coolant recovery bottle wilpopiooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooool still have coolant but the rad low. GoodluckJoe
1982 Chevy C10 temperature sensor reads cold even when the truck is warm. Warm air from the heater. Is it the sensor or the gauge?
It is easier and cheaper to replace the temperature sensor--try that first
What is causing your temperature gauge to be in the cold position and radiator fluid to leak?
A low coolant level could cause the temp gauge not to read correctly. A faulty temp gauge sending unit could also be the cause. The coolant leak, you would have to find the source of the leak to determine the cause.
1993 ford explorer limited edition temperature gauge always reads cold Changed thermostat but this is not the problem What might be wrong and how would you fix it?
check the connections behind the gauge they could pop loose
Why does the temperature gauge act erratic goes from cold to hot quickly then drops to cool When in red there is no heat from heater When in cool there is hot air from heater?
Low coolant, check when engine is cold.
