You need to understand that when your car's temperature is very high, it is a significant issue, and it is not advisable to drive an overheated vehicle. If your car is experiencing a high temperature, you need to turn off the air conditioner and quickly open the windows.
If this does not minimize the overheating, turn on the heater to its maximum setting. If this doesn't work, pull over to the side of the road, turn off the engine, carefully open the hood, and wait for the vehicle to cool down.
When the engine is hot, never open the radiator cap because coolant might spray and burn you. Take the vehicle to a mechanic as soon as it has cooled.
