What does a temperature light in your car mean?  

Do you see the sign of a thermometer with two wave signs beside it? That’s the temperature light. If you see this light blinking, your engine is probably overheated, and you’ll need to seek help immediately.  

Coolants like ethyl glycol and water in proportion manage your car engine. When this mixture runs through the engine, the engine stays cool. This indication also means that it is safe for you to drive. The temperature lights start blinking when the coolant levels drop, and the engine starts heating up.  

The lights begin to flash as the temperature inside the car drops. This trouble can happen anytime. Hence, when something like this happens, it is important to understand the reasons behind it and what can stop the temperature light in your car from blinking.

What switches the temperature light in your car on? 

Here are some of the common causes why the temperature light in your car starts blinking: 

Frequent stalling 

While driving, it is important to maintain your engine cool to ensure it works properly. When the engine heats more than it should, it can harm your car and put you at great risk. Due to this overheating, the temperature light in your car can switch on. However, once the light turns on, the risks may reduce. 

Additional load 

Putting an additional load on your car or making it work more can make it switch on. For instan, your engine strains to pull the load if you’re driving uphill road. With an extra load, the engine also puts more effort into equalizing the temperature and airflow inside the car. This load can furthermore increase the leakages and mechanical damages on your car. 

Extreme weather 

Driving in extremely hot weather, with ac on and braking frequently, you can switch on the temperature light in your car. Hence, when you feel that your ac has a problem, take your car to a mechanic immediately. Also, remember to use normal water to fill the container. In any case, visit a mechanic and check your car before taking further steps. 

Mechanical fault 

At times, there can be internal damage that cannot be visible on the outside. The parts that mostly face damage are the radiator, service belt, and water pump. These are also the parts that take up extra energy. As a final step you can just , dry your gasket and then try restarting the engine. 

Drop in coolants 

If your coolant amount is less or falling, then the temperature light in your car can come on. If your car uses up all the coolant, this might result in a drastic drop in your coolant level. There are also chances of a leak which sucks out all the coolants.
