What to Do (& Not To Do) When Your Car Overheats

Why Does the Vehicle Engine Overheat?

Many drivers face the problem of overheating cars, especially in the summer. There is overheating while the energy required for the engine to run is released. After a while, this heating may cause the engine and its connected parts to lose their function or be damaged. It is essential to pay attention to the temperature issue in the vehicle for driving safety and engine life. 

Engine parts are in a series of motions to start the vehicle. The energy generated is necessary for the movement of the engine and, therefore, the car. However, as energy is released, there is also heating. This is the reason that melts the parts - burns them, and prevents the engine from starting. Mechanical engineers realized the importance of using some parts to avoid this heating over time, and with the development of these parts, the temperature was brought under control. The maintenance of these parts is therefore essential.

Which parts prevent overheating in the car?


In motor vehicles, oils and fluids are essential. The fluid used to remove the heat from the engine and keep the engine at the desired operating temperature is also called coolant.

Cooling pump

It works for the circulation of the coolant. The rotation speed of the pump and the circulation speed of the cooling water is similar.


It is the mechanism that cools the coolant. It has channels through which the cooling water will flow. After the liquid passes through the pump, it goes to the engine, warms up during cooling, and cools in the radiator.


It is responsible for adjusting the amount of flow that will go to the radiator. It measures how hot the water coming from the pump is getting. When the engine rises above the desired temperature, the thermostat is activated.

Temperature sensor

The task of the temperature sensor is to determine the coolant temperature and report it to the engine control unit.

In summary, there are essential parts such as the engine temperature sensor and the temperature gauge in vehicles, which allow controlling the heating. Here, the heat can be prevented by the harmonious operation of these parts. As you can imagine, problems with these parts can also cause the engine to overheat. 

Why Does the Engine Overheat?

1. Refrigeration Equipment Problems

Problems with cooling parts are the most common cause. We can list some of them as follows:

  • Defective temperature sensor (Incorrect measurement of the sensor prevents the radiator fan from activating, which may cause the temperature to rise)
  • Insufficient cooling water
  • The cooling fan not working
  • Broken fan belt
  • Water pump failure
  • Having a fluid leak
  • Air in the coolant
  • Clogging inside the radiator due to corrosion

2. Driver Errors

The way the vehicle is used can also cause the engine to overheat more often. The engine may overheat for incorrect gear shifting, overexertion of the machine, and driving at high speed for long hours.

What To Do If The Engine Overheats?

Please do not stop the vehicle and let it idle when the temperature rises. Because in this case, the radiator will not cool down. You need to take your foot off the gas and slowly stop as you continue forward. Opening all the vehicle windows and turning on the heater also helps to lower the engine coolant temperature. Then check the cooling system. Be careful when you check the parts because the parts that get hot here can also harm you.

How to Avoid Engine Overheating?

For cooling system maintenance, have the following parts serviced and checked:

  • Radiator hose check,
  • Antifreeze water change,
  • Temperature sensor and indicator control
  • Coolant control
  • Cooling fan control and maintenance
