What does it mean when your car temperature gauge goes up and down?
The primary reason your car temperature gauge goes up and down while driving is simply because a component in your cooling system is not functioning correctly. This could be the thermostat valve, radiator hoses, radiator fan, the temperature gauge, or the coolant itself that circulates around cools off the engine.
Is it normal for temperature gauge to fluctuate?
A car’s temperature gauge rarely falters with age. Hence a fluctuating gauge is reason for concern, as it points to possible faults elsewhere. One common cause is a defective thermostat, a component that is inexpensive and easy to replace.

Why does my thermostat go up and down?
When your thermostat is not working properly or is stuck closed, this will not allow the coolant to properly circulate through the engine, which may cause the engine temperature to fluctuate erratically or in some cases just remain hot.
What causes fluctuating body temperature?
Your Temperature Naturally Fluctuates Your body temperature doesn’t remain constant, however, it fluctuates according to your circadian rhythm. Generally, this means your body temperature is at its lowest a few hours before you wake and its highest an hour or two before bed.
Why is my temperature gauge going up?
If the temperature gauge reads high, it could mean your engine is overheating. Another reason your reading might be high is you could be losing coolant. A small leak or evaporation may cause your radiator to slowly lose coolant. A third reason your temperature gauge reads high could be because the thermostat is broken.
Why is my car overheating with a new thermostat and radiator?
You could be having a problem with your radiator being clogged up. This will cause the flow of the coolant in the system to be restricted, causing the truck to overheat. A clog in the heater core could also cause this problem. However, if the car is still getting heat, the heater core can easily be ruled out.
Why is my temperature gauge high but car not overheating?
