According to Mark C. Sargent, Technical Director at Car and Driver (USA), this phenomenon is not only uncomfortable but can also lead to serious damage if not fixed in time.
Here are some of the main causes of unusually hot cars pointed out by Mr. Mark C. Sargent:
1. Refrigeration system broken
One of the common causes of unusually hot vehicles is due to broken or ineffective cooling systems.
The vehicle's cooling system includes many parts such as water cabin, fan, water pump and cooling water pipes. If one of these parts is damaged or not working properly, the engine temperature will increase.
2. Low cooling water level
cooling water plays an important role in keeping the engine temperature stable. If the cooling water is lacking or not replaced periodically, the engine will not be able to heat properly and can heat up quickly. Therefore, the vehicle owner should check the cooling water level regularly and supplement when necessary.
3. Dust and debris in the cooling system
The vehicle's cooling system can also be blocked due to dirt or debris accumulating in pipes or water cabinets. This reduces the system's heat loss and causes the engine to heat up abnormally. Regular cleaning of the cooling system is very necessary to ensure optimal cooling performance for the vehicle.
4. errors from the temperature sensor
The temperature sensor of a car is responsible for monitoring the temperature of the engine and sending a signal to the control system. If the sensor is faulty, it can report incorrect information about engine temperature, causing the driver to not recognize the unusual heat of the vehicle.
Regular temperature sensor checks and replacements are an effective way to prevent this problem.
5. Issues from the clutch or engine
When the engine is broken or the clutch is not working stably, the vehicle may experience overheating due to the engine having to work too much. Experts recommend that car owners take their cars to reputable maintenance centers for regular engine and clutch inspections.
