cold all the time?? a bad thermostat, staying open all the time. when you first start the car the engine needs to warm up fast so the thermostat will stay closed so coolant will only be circulated thru the engine and once the coolant has reached a certain temp it will cause the wax pellet in the thermostat to expand and circulate the coolant to the radiator to expel the heat. but if your thermostat is stuck open coolant is constantly being circulated to the radiator from cold start and is not allowing the engine to heat up properly causing poor gas mileage. to find the thermostat find the lower radiator hose (just trace the hose coming from the bottom of the radiator) to the engine block the hose should connect to a small housing held in by 2-3 bolts that's the thermostat housing remove that and inside is your thermostat by the way drain you coolant before you do that.
or your gauge could be bad.

What does it mean when your coolant temperature gauge reads cold even when warm and the idle is high?
Low Coolant or faulty gauge
Why is car temperature gauge reading cold whilst you are driving?
at the beginning it will be cold, but it will warm up as you start driving
Why does your car rev up and temperature gauge show cold?
Thermostat is gone, change it
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 heater blow cold and temperature gauge stays on cold on a 1994 Chrysler LeBaron?
Most likely cause is a failed engine thermostat.
Why is your refrigerator getting to cold?
turn your temperature gauge down. it should be around 3 or 4 I believe.
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 is the part on the engine block that sends the information to the hot and cold temp gage called?
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.
Why does your temperature gauge show hot when you drive less than 5 miles in cold weather?
Because Science.
How can I tell if my thermostat is bad?
Does vehicle overheat rapidly? Do you have heat? Does temperature gauge show that vehicle is running cold
How do you read the auto temp gauge to know where the needle should be when the temperature is correct?
normally the gauge should be in the middle.(between hot and cold) that is concider operating temp.
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.
