The car engine can overheat for several reasons:
loss of refrigerant
low oil level
forced march
Car at low speed for a long time
In any case, it is harmful for the engine to keep it like this for a long time, so we must lower its temperature immediately.
First we must complete the oil and coolant if they are low, force the radiator fan to turn on, turn on the heating fan with maximum temperature and speed.
Wait 3 minutes for the radiator to cool down and then start the engine for about 20 seconds, allowing cold coolant to enter the engine.
Repeat this procedure about 4 times, so you will notice that the engine temperature drops quickly.
