Why do cars overheat? Precautions against overheating

Especially on hot summer days, you can see that your car is overheating with smoke coming out of the engine. This is not a normal situation and there are steps you can take to prevent it. Let’s see with all the details why the cars heat up, what to do in case of heat and what precautions you will take.

Even if it never happened to you, you must have witnessed smoke coming out of a car’s engine due to overheating, at least in movies and TV shows. It is not uncommon for the car to overheat, but it does happen to many drivers, especially on hot summers. To avoid overheating for many different reasons, However, there are many effective steps you can take.

There is no single answer to the question of why cars overheat, and there is no single action you can take against this situation. Because even though the principle of car operation is simple, its working system is not at all simple and, therefore, even a small problem in the smallest part can cause a dangerous overheating. Bride why cars heat up Let’s see with all the details what to do in case of heat and what precautions you will take.

Why do cars overheat, what should we do, what precautions should we take?

First of all, what is heat?

In its most basic definition, overheating is when something heats up more than normal and becomes inoperable. The heat experienced in the car, as a result of the engine and its parts not working properly. represents the heating event. This temperature can be seen as a small change in value in the instrument panel or as dense smoke.

Why do cars overheat?

The car operating system is simple; Some parts run, activating the engine, and the vehicle moves with the resulting energy. In this process, some heat is produced. When the engine parts in question or the engine itself are not sufficiently cooled by the cooling systems, the heat increases and overheating occurs. There are some main reasons why the car overheats;

  • The temperature sensor is not working properly
  • Not enough refrigerant
  • The cooling fan is not working properly
  • Breaking the fan belt
  • Circulation pump does not work properly
  • You are experiencing a leak
  • The air is mixed with the refrigerant
  • Corrosion radiator obstruction
  • Incorrect driver change
  • Excessive engine tension while driving
  • Prolonged cruise at high speed

The main reasons for overheating the car are usually these. Under normal conditions, important parts such as coolant, cooling pump, radiator, thermostat, temperature switch Keep your car temperature under control. However, due to the problems experienced in these parts, the engine parts or the engine itself cannot be cooled and the heat increases and causes overheating.

What should we do when our car overheats?

As you drive along the road, you suddenly see the warning light on the instrument panel come on or, worse, smoke coming out of the hood. First, keep calm. Slowly slow down and turn off the ignition as soon as possible by pulling the vehicle. Never leave the vehicle running because the heat will continue to rise while it is still running.

After turning off the ignition, open all windows and allow the vehicle to breathe. Get out of the vehicle and opening the hood Allow the engine to breathe directly. If there is intense heat, turn on the heater. While the heater is running, it will speed up the cooling process as it will take the heat from the engine and dissipate it.

Depending on the temperature of the vehicle, the windows, hood and heater should be open. Wait 10 to 30 minutes. After this time, get in the car and turn on the ignition. Check the temperature level on the instrument panel. If all goes well, start the engine. If the engine makes strange noises or does not start at all, you should call the roadside assistance service. Most of the time it overheats due to lack of coolant, so keep one in the trunk.

Precautions you can take to prevent the car from overheating:

  • Park your car in the shade.
  • Use the canopy.
  • Apply window film.
  • Leave the car windows slightly open.
  • Open the floor grilles.
  • Set the air conditioning to fresh air.
  • Watch the temperature indicator.
  • Turn on the heater from time to time.
  • Check the engine coolant frequently.
  • Do not neglect radiator cleaning and other maintenance.
  • You may need to replace the car battery.

Park your car in the shade:

It will be difficult in areas where even normal parking is not easy to find, but especially on hot summer days. instead of leaving the car in the sun Try to find a shady spot. Covered car parks are much better options. Even if you don’t find all the shade, it’s extremely important to find an area that doesn’t get direct sunlight, at least.

Use the canopy:

Glass shutters produced for car windows or directly to cover the entire car car covers it is extremely useful. Thanks to its reflective properties, they will prevent the sun’s rays from directly affecting and heating your car, so that they will at least avoid the heat caused by the hot air.

Apply window film:

You may be a little scared because of the recent window movie mess, but don’t worry, window movies have certain proportions. You can’t disappear completely, though At least applying a film that blocks some sunlight will prevent overheating.

Leave the car windows slightly open:

Some days even when the weather is not warm enough to open the windows or turn on the air conditioning. It may be hot enough to heat the engine. So make sure the windows are always slightly open. You can also leave the window slightly open when you park your car in front of your eyes.

Sales open to the ground:

Vehicle vents are arranged to provide airflow from different points. Top ventilation creates a much cooler atmosphere though Remember that hot air rises. Therefore, first open the floor ventilation so that the hot air goes up and out. Then you can adjust it to your liking.

Set up fresh air conditioning:

Air conditioners have different configurations. The most common recirculation configuration is used, but no fresh air is taken from outside in this configuration. Adjust your air conditioning at least every 10 minutes If you set it up to get fresh air from outside, you will avoid overheating.

Watch the temperature indicator:

Many drivers do not notice the temperature of their car until it is dangerous or until smoke comes out of the engine. Don’t be one of them. Check the temperature indicator from time to time, especially during the hot summer months, on long journeys, and at high speeds.

Turn on the heater from time to time:

It doesn’t make much sense to run the car heater on hot summer days, but at least it does when you take a break or every hour Running the heater for a few minutes will dissipate engine heat and reduce the risk of overheating.

Check engine coolant frequently:

Even when you take your vehicle to the authorized service, the first place to look will be water and oil. Therefore, these are extremely important. Because It is a good idea to check the engine coolant from time to time. In fact, it is best to have one in the trunk, just in case.

Don’t neglect radiator cleaning and other maintenance:

Don’t forget to have it cleaned regularly, as the radiator is not working properly is one of the most common causes of overheating. with radiator It is also helpful not to neglect the hose, antifreeze, temperature sensor, indicator, and fan controls.

You may need to replace your car battery:

If you have been using your vehicle battery for more than 3 years it does not produce enough energy and therefore the engine may be overheating working harder. During routine inspections, also have your vehicle battery checked and replaced if necessary.
