Why Do Cars Overheat? Precautions Against Overheating

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

Even if it has never happened to you, you must have witnessed smoke coming out of the engine of a car due to overheating, at least in movies and TV shows. It is not normal for the car to overheat, but it happens to many drivers, especially in hot summers. In order to prevent overheating due to many different reasons, However, there are many effective measures you can take.

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

Why do cars overheat, what should we do, what are the precautions to be taken?

First of all, what is heat?

In its most basic definition, overheating is when something gets hotter 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 warming event. This temperature can be seen as a small value change on the instrument panel or as a dense smoke.

Why do cars overheat?

The operating system of cars is simple; Certain parts work, activating the engine, and the vehicle moves with the resulting energy. In this process, a certain 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;

  • Temperature sensor not working properly
  • Not enough coolant
  • Cooling fan not working properly
  • Breaking of the fan belt
  • Circulation pump not working properly
  • Experiencing a fluid leak
  • Air mixing into the coolant
  • Radiator clogging due to corrosion
  • Incorrect gear shifting of the driver
  • Excessive engine strain while driving
  • Prolonged cruising at high speed

The main reasons for the car overheating are generally like this. Under normal conditions, important parts such as coolant, cooling pump, radiator, thermostat, temperature switch Keeps the 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 the car overheats?

While driving normally on the road, you suddenly saw the warning light come on on the instrument panel, or worse, smoke coming out of the hood. First of all, stay calm. Slowly reduce your speed and turn the ignition off as soon as possible by pulling the vehicle over. Never leave the vehicle running because the heat will continue to rise as long as it continues to run.

After turning off the ignition, open all the windows and let the vehicle breathe. Get out of the vehicle and by opening the hood Let the engine breathe directly. If there is intense heat, turn on the heater. While the heater is running, it will accelerate 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 between 10 and 30 minutes. After this time, get in the car and turn on the ignition. Check the temperature level on the instrument panel. If everything looks normal, start the engine. If the engine makes strange noises or does not start at all, you should call roadside assistance. Most of the time it gets overheated due to lack of coolant, so have one in your trunk.

Precautions you can take to prevent the car from overheating:

  • Park your car in the shade.
  • Use canopy.
  • Apply window film.
  • Leave car windows slightly open.
  • Open the floor vents.
  • Set the air conditioner setting to fresh air.
  • Keep one eye on the temperature gauge.
  • 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 your car in the sun He tries to look for a shadow place. Covered parking lots are much better options. Even if you can’t find full shade, it’s extremely important to find an area that won’t get direct sun, at least.

Use canopy:

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

Apply window film:

You may be a little scared due to the recent window film mess, but don’t worry, window films have certain proportions. You can’t completely black out but At least applying a film that will block the sunlight a little will prevent heating.

Leave car windows slightly open:

Some days even when the weather isn’t hot enough to open the windows or run the air conditioner. It may be hot enough to warm the engine. So make sure the windows are always slightly open. You can also leave the window open a little when you park your car in front of your eyes.

Open floor vents:

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

Set the air conditioner setting to fresh air:

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

Keep an eye on the temperature gauge:

Many drivers don’t notice their car’s temperature until it’s dangerous or smoke comes out of the engine. Don’t be one of them. Check the temperature gauge occasionally, especially in hot summer months, on long trips and at high speeds.

Turn on the heater occasionally:

It doesn’t make much sense to run the car heater on hot summer days, but at least it’s when you take a break or every hour If you run the heater for a few minutes, the heat in the engine will dissipate 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. So these are extremely important. Because It’s a good idea to check the engine coolant from time to time. In fact, it’s best to have one in your trunk, just in case.

Do not neglect radiator cleaning and other maintenance:

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

You may need to replace the car battery:

If you have been using your vehicle’s battery for more than 3 years not producing enough power and therefore the engine may be overheating by working harder. During routine checks, also have your vehicle’s battery checked and replace if necessary.
