Is it harmful to the car to run continuously for 12 hours?

[LaKatherine]

The car itself has no problems or hidden dangers, and normal driving will not damage the vehicle. Driving precautions: 1. Cooling difficulties: Some of the heat generated by the engine is discharged through the exhaust, while the engine itself relies on the radiator for cooling. For cars that are old and poorly maintained, if the cooling system cannot keep up, the water temperature in the radiator will rise sharply, leading to boiling and smoking, commonly known as "overheating," which can cause significant damage to the engine. 2. Engine oil leakage: For many older cars, running continuously for 12 hours can cause the engine to leak oil due to aging, potentially leading to spontaneous combustion. 3. Impact on power output: Long-term operation of the engine generates excessive heat. If the temperature becomes too high, the exhaust system will activate self-protection, reducing the engine's performance and thereby decreasing power output. If the car is driven for long periods frequently, the damage to the engine and exhaust system is self-evident.
