Indeed, the cooling fan is the main protector of the power unit against overheating. It turns on when the temperature of the antifreeze reaches certain values and turns off when it returns to normal. But what happens if you turn off the engine while it (the fan) is still running? Many people think that heat stroke is inevitable. That is, if you do this regularly, the oil will begin to break down and the connecting rod and piston group will wear out.
If we look at the measurements of a number of European car publications, it can be said that when the engine is switched off, the coolant temperature rises anyway. Say, in the heat of the “jump” it can be as much as five degrees. Not much. Therefore, it is important to focus on the technical characteristics of a particular vehicle and its operating conditions.
However, the technology is now very advanced. For example, if the car has a turbo timer or is equipped with an additional water pump, then you can turn it off immediately and not think about any consequences. The electronics independently drives the antifreeze through the system, cools it with a fan and only then does the noise stop under the hood.
And in other cases, the car, put on the alarm, will work for a few more minutes. This clever “brain” also cooled her down. For example, a similar solution is present on the old Ford Mondeo.
As for the aspirated, there are no solutions listed above. However, under normal operating conditions, you should not be afraid of temperature jumps after the end of the work of the “heart”. They are not critical for a cast iron cylinder block.
However, if the driver drove for a long time in the heat, and even through a mountain serpentine, then you need to let the car idle for a few minutes. After all, these are all increased taxes that are not in vain. The lubricant may begin to break down slowly and the antifreeze may boil away. Especially if a concentrate was poured into the system and the dosage was wrong. That is, there was too much distilled water in the composition.
