What causes the temperature gauge to go down while you are driving?
What causes the temperature gauge to go down while you are driving?
The core, and thus the heating system, gets its thermal energy from the engine’s cooling system. Thermostat valves can fail in one of three ways: open, closed or stuck halfway. If the valve sticks in the closed position, coolant will constantly recycle through the engine without going to the radiator, causing the engine to overheat.
What should car temperature be at highway speeds?
Car temperature drops to a little less than 1/4 at highway speeds. Any reason to be concerned? Car is a Mk1 Golf. Driving around town the temperature behaves normally – it sits at the middle of the gauge, sometimes goes a little higher if I’m sitting in traffic but not much.
What happens when your engine temp drops to cold?
If your thermostat failed, it wouldn’t turn cold while driving. It would never get hot. THe thermostat is supposed to open as the water temp goes up. If it is stuck open, the water would never heat up. When your indicator is cold, are you getting heat from your vents??
How does the temperature of the car change?
Driving around town the temperature behaves normally – it sits at the middle of the gauge, sometimes goes a little higher if I’m sitting in traffic but not much. However, on the highway the temperature slowly decreases until it sits just below the 1/4 mark. Once back in city traffic it goes back up again and acts normally.

When does the needle go to the middle of the gauge?
If the needle goes to about the middle of the gauge, that means the engine has reached normal operating temperature, usually between 180 an 210°F. It goes up quickly after starting, then stabilizes. This is normal.
Why does the gas needle go up and down?
The needle may rise above the midpoint if you are travelling up a long uphill grade, especially if your vehicle is carrying a heavy load, because the engine is burning more fuel to work harder (bigger fire). It should return to normal as you level out or go downhill. You may notice that the needle moves up and down a little while you’re driving.
What do you mean by temperature gauge is fluctuating?
Temperature gauge is fluctuating, sometimes showing overh… Q: Temperature gauge is fluctuating, sometimes showing overheating.
If the needle goes to about the middle of the gauge, that means the engine has reached normal operating temperature, usually between 180 an 210°F. It goes up quickly after starting, then stabilizes. This is normal.
When does the car temperature gauge go up?
Your car temperature gauge goes up from 100 to 200 degrees F in 3 to 5 minutes after your car engine starts running, that is normal, because your car thermostat is close.
Why does the temperature gauge stay on cold?
Air in the coolant system can also cause the temperature gauge to stay on cold if there is an air bubble right at the sensor spot. This can also often be indicated with a fluctuating coolant temperature gauge. If you suspect air in the coolant system, you have to bleed your coolant system with a unique technique.

What causes the temperature gauge to spike up?
Temperature gauge spikes up after driving for about 5–10 minutes, then returns just as quick to normal. Happening more lately wheezing traffic causing engine to sound likes it’s working harder to accelerate and temp fluculates My car has 100500 miles. My car has an automatic transmission.
Why does the coolant temperature gauge stay on cold?
The most common causes of a coolant temperature gauge which stays on cold are with the coolant temperature sensor itself. It’s recommended to check this component first.

What can I do if my temperature gauge stops working?
Any decently equipped auto repair shop can use a *professional quality scanner* set to functional test and check the signal to ALL GAUGES in the instrument cluster.. Then each gauge can be tested with the scanner to see if it is responding accordingly .. Im talking about a REAL automobile scanner that probably cost 8k $ and up ..
