Why Does My Car Keep Overheating?

The term “overheating,” which describes a common issue with motor vehicles, refers to a condition when the engine is too hot to run. Drivers may find this prospect to be a nightmare, particularly in the heat.

Many drivers who are actively driving have undoubtedly pondered about what to do with their automobile while the temperature gauge is illuminated at least once. Despite the fact that issues with the cooling system of the automobile are typically to blame for the engine overheating, it is crucial to treat this situation seriously, look into potential reasons, and do regular maintenance on the car without skipping a beat. because the vehicle’s engine, which is its most essential component, can suffer catastrophic harm if it overheats.

How Much Should a Car Temperature Gauge Be?

The temperature indicator on the dashboard of the car shouldn’t go beyond 90 when driving safely. The temperature light turns on when the needle rises above 90, signaling that the engine is getting too hot.

Why Does the Car Overheat?

There are several reasons why cars overheat. The main causes of overheating can be listed as follows:

  • Low or exhausted coolant (antifreeze)
  • Leaks in the cooling system
  • Burning of the gasket
  • thermostat failure
  • Fans not working due to defective temperature switch
  • Cooling fan not working properly
  • Loosening or breaking fan belt
  • Deterioration of the circulation pump, which keeps the temperature level of the engine at a certain level
  • Air in the coolant
  • Clogging of radiator cores
  • Situations caused by driver errors, such as not driving at the appropriate gear and speed

What Happens When the Engine Overheats?

Today, although vehicles are produced more durable, in some cases the heat produced by the engine can exceed the required level. Even a minor malfunction in the cooling systems, which prevents the temperature from reaching the level that will damage the engine, can cause the vehicle to overheat.
In the overheated vehicle, the engine coolant cannot perform its function. Continuing on the road in such a situation leads to the development of a series of problems. As a result, the damage is not only to the engine that has become inoperable; it can also happen in vehicle parts that keep the engine running.

What Should You Do When Your Vehicle Overheats?

If your vehicle overheats;

Turn on the Heater

Turning the heater on can help the car cool faster by drawing heat away from the engine and into the passenger compartment.

Pull Over

It will be the right move to turn the ignition off without losing time by pulling the vehicle to a cool and shaded place.


After turning off the ignition, it is necessary to wait for the temperature in the engine and the cooling water to decrease.


After the vehicle has cooled down, the radiator cap should be opened to check the water level and if the water is low, clean drinking water should be added to the compartment. While doing this, it is very important that the vehicle cools down completely. Otherwise, boiled water may cause burns with the effect of pressure or steam.

Take to Service

If there is no decrease in the water level in the radiator, the vehicle must be returned to a mechanic immediately.
Editor’s Note: In any case, you should not forget that you should not neglect the periodic maintenance of your car in order to avoid overheating problems in your car!
