Turn on the heating. When the water temperature reaches 90, it drops directly to 60.

It is normal for the water temperature of warm air to drop from 90 degrees to 60 degrees immediately, so the owner need not worry. First of all, heating the car with warm air will reduce part of the temperature of the refrigeration liquid circulation system and improve the heat dissipation characteristics of the car, so the overall water temperature of the car will be reduced.

Secondly, the water temperature of the engine depends on the front cooling water storage tank and the wind from the fan. This circulatory system is a small circulatory system. Therefore, turning on the warm air is equivalent to changing the direction to improve the total heat dissipation area of the water storage tank. The heat generated by exchange increases, and the water temperature of course drops, which is also the reason why the water temperature of the car turns on the warm air.

In addition, heating air in winter will continuously consume the heat of the engine. If the engine displacement is small, it will lead to the situation that the heat consumed by heating air cannot be offset by the engine operation. When warm air is turned on, it will easily lead to a rapid drop in water temperature. Naturally, it is normal for the water temperature to drop.

I suggest that when driving at a relatively cold temperature, the owner can turn on the warm air until the vehicle is completely warmed up, preferably at 90 degrees. After driving for a certain distance, the water temperature will generally become normal and the engine will be well maintained.

Remember not to fall asleep in the car when the warm air is turned on. Because the air inside the car changes under the action of central air conditioning when the car is driving, carbon monoxide caused by the engine finally enters the car, which is easy to cause carbon monoxide poisoning in a closed car.
