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 causes temperature gauge in car to be cold?

If you are referring to the temperature reading on the gauge, then it's possibly a bad thermostat.It will also read 'cold' until the engine has sufficiently warmed up.Lack of fluid (water and/or antifreeze) in the radiator.Low engine temperature (bad thermostat).Low coolant level.Bad gauge.Wiring issue.Coolant temperature sensor bad or not correctly grounded.Problem in an electornic control module.

Check your thermostat. Looks like it is stuck open and needs replacing. That could be why your engine is running cold. Atleast its not stuck in the closed position.

Most likely cause is a failed engine 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...

turn your temperature gauge down. it should be around 3 or 4 I believe.


What should you do if on your '93 Taurus the temp gauge fluctuates and you can smell antifreeze?

Make sure it is full of coolant. There probably is a small leak causing the smell. Check it cold as sometimes it leaks cold but not hot.

In the engine block of a vehicle, the part which is responsible for sending information to the temperature gauge is called the temperature gauge sending unit.

Probably - your head gasket is blown. Antifreeze will be coming out of the tail (exhaust) pipe.

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.


Why does the temperature gauge act erratic goes from cold to hot quickly then drops to cool on a 1993 mercury villager?

Can be a defective temperature sending unit. If you just chance the coolant can be air trapped in the cooling system. You would need to bleed all air from the system. Can also be a defective gauge, but highly unlikely.

heater core possibly plugged and leaking
