What drivers used to know - using the heater to protect the engine
08/11/2017
Anyone sitting in a modern car today hardly ever thinks about the heating (and air conditioning). Digitally set to 22 degrees, electronics and various actuators ensure that the interior gets warm (or cold) as quickly as possible and that the temperature can then be kept constant.
Drivers used to think a lot more when using a car. This began when starting the car in winter. The interior heating was then opened as late as possible so that the cooling water circuit had less volume and the engine warmed up more quickly. This protected the sensitive drive unit and as soon as it was warm, the heating could be turned on without any problems.
The situation was exactly the same when the engine threatened to become too hot. Then the maximum heating effect was selected to remove some of the temperature from the cooling water. The health of the engine was simply more important than the well-being of the passengers.
Incidentally, both recipes still work for older cars today.
But perhaps there are other recipes on this subject that were familiar to drivers in the past? Just comment ...
