What To Do If Your Temperature Warning Light Comes On. STOP DRIVING IMMEDIATELY!. Pull over to the side of the road as soon as it is safe to do so, then shut off your engine and wait for things to cool down. WARNING: Do NOT attempt to open the radiator cap! The radiator contains hot water under high pressure.
Accordingly, how do you fix coolant over temperature?
What to Do When Your Engine Overheats
- Kill the A/C and crank the heat. Immediately turn off the air conditioner to reduce stress on the engine. …
- Find a safe place to pull over. Pull over and shut off the car. …
- Check and add coolant (if you have it). …
- Restart the engine.
Herein, is it safe to drive with the temperature light on?
While your car might still be drivable, continuing to run it with the engine temperature warning light on will only cause further damage and can lead to more costly repairs. At the very least, you should stop and let the engine cool down for around half an hour before driving further.
What does the thermometer symbol mean on a car?
A warning dashboard light that looks like a thermometer means the engine’s temperature is beyond the normal limits, and it should be checked immediately to keep your car from overheating. You’ll want to check the coolant level and make sure the radiator cap is properly sealed as well as look for coolant leaks.
Normal coolant temperature varies from car to car. However, the normal engine temp should be in the range of 195 to 220 degrees Fahrenheit. Though, most vehicles do not display the degrees of the coolant temp on the instrument cluster. They have markings that indicate low and high temperatures.
The usual cause is that there’s insufficient coolant in the system to keep the engine running at optimal temperatures. If a red engine temperature warning light comes on, it’s essential that you stop and turn the engine off as soon as it’s safe to do so.
In short, the most common cause of a car overheating then going back to normal is a bad or failing thermostat and now is failing to control the flow of hot water through the radiator to cool the engine down.
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.
Dashboard warning light: When coolant/antifreeze is low, your vehicle may notify you on its dashboard. However, not all cars are equipped with this feature. Rising temperature gauge: A rising temperature gauge may be due to an increase in your engine’s temperature.
