What Should You Do When The Temperature Warning Light Comes On?

Engine damage can happen for many reasons, and overheating is one of them. For this reason, it’s necessary to take the coolant temperature warning light seriously. You will find it on the dashboard gauge cluster. It looks like a thermometer or shows the word ‘temp’ or ‘engine overheating.’ Whenever these words flash or the sign lights up, your car is in danger.

The computer system of your vehicle monitors the overall fluid level and the coolant temperature. The coolant temperature warning light comes on when there’s a problem with the fluid level or the temperature.

What The Coolant Temperature Warning Light Means

When the engine is started, the coolant warning light will illuminate for a few seconds to check the light bulb. In case that the coolant temperature warning light is still illuminated after starting the vehicle, it will signal that the vehicle is experiencing trouble in the system. And the most common reasons for a glowing of this temperature light car are usually the temperature or the fluid level of the coolant.

Remember once the low coolant appears means that your car has experienced some leakage and needs to be repaired as soon as possible. Otherwise, your car will be in low coolant mode again and the motor overheating risk will occur again. The car’s computer will often save the code in case of a problem, which to get the tools through the scan and connect, this is an extremely useful tool in the process of identifying problems for the coolant temperature warning light.

The Causes of Coolant Temperature Warning Light Comes on

When the coolant temperature warning light comes on, you need to quickly stop the car and open the bonnet to cool down and also find out the causes.

Coolant is considered to be an intermediate that transfers the heat from the engine body to the cooling tank. Coolant water quality will have a dramatic effect on the efficiency of the cooling system. If the water is not sufficiently cooled, the parts in the vehicle will overheat, allowing for extremely damage.

When the coolant temperature warning light goes on, the engine is seriously overheated, which can be caused by overheating, lack of cooling water or a cooling system that is having trouble. At this point, you need to park your car in a safe area with shade (if it’s summer) to open the bonnet.

If you observe that the water is still boiling, you can leave the machine in idle mode until the temperature drops below the red line and then turn off the machine (do not turn off immediately because it can cause heat congestion due to not saved water and fan do not work, make boiling water more intense). When you have cooled down, turn off the engine and you can check the cooling water to see if the water is at risk of leakage. If the water is lacking, it should be added with pure water and continue to run. Pay extra attention and follow up to find out the cause. In fact, there are many cases of heavy vehicles, which are too high, can cause the vehicle overheat, just let the car rest and operate again when the machine cooled.

You should never dare to continue driving when the light is on. Pull over as soon as possible and shut the engine off. Wait for at last 30 minutes for the engine to cool down. Wear a thick glove or wrap the hand with a thick towel or a piece of rag and remove the radiator cap to check the coolant level. Never do this when the engine is still hot because the steam coming out of it can burn you.

If the fluid level is low, add plain water and drive to a nearby repair shop to check everything thoroughly. Remember that it’s just a temporary solution. Low level of coolant means there a leak somewhere, which is needed to be addressed quickly.
