Why does my temperature gauge keep going up and down?
Why does my temperature gauge keep going up and down?
One common cause of a temperature gauge that malfunctions is the thermostat. Sometimes the thermostat gets stuck open, which can cause the temperature gauge to “warm up” slowly, never move back down to operating temperature range, or fluctuate randomly. If the thermostat is not stuck open, it may simply need to be replaced.
What does the temperature gauge on a car mean?
The temperature gauge is pretty straightforward. It shows whether a vehicle’s engine is hot or cold and indicates a safe zone in between. While some gauges have a digital readout that shows actual temperature, others simply have a light indication for hot and cold temperatures. What do you need to know about car temperature gauge?
What should the temperature of the engine be?
Read on and learn everything you need to know about your car’s temperature gauge. The ideal engine temperature should be somewhere between 195 and 220 degrees. An engine is operating normally when the needle points at the center or near the center of the gauge.
How can I tell if my light gauge is hot?
Check the gauge if the needle moves toward “Hot”, the wire from the gauge to the sending unit has an open or bad connection. If it does not move, connect a test light by grounding one end to a good known ground and the other end to positive side of the gauge (typically a pink wire).
What should you do if your temperature gauge is high?
What to Do If Your Temperature Gauge is High. If your temperature gauge is reading high, it means your car is overheating. This is a very serious matter and you should never drive an overheating car. If your car starts to overheat, shut off the air conditioner and open the windows immediately.
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.
