18 Carola turns on warm air in winter, and the water temperature drops by 83 degrees. What happened to speed?

In this case, this problem may occur if there is no thermostat or the thermostat is removed. In the final analysis, the choice is two points. One is that the heat generated by the engine is low and the other is that the temperature is too low. This is normal, don't worry. ?

It is normal for the water temperature to drop directly from 90 degrees to 60 degrees when the warm air is turned on, so riders don't have to worry. First of all, heating the car with warm air will reduce the temperature of some coolant circulation and increase the heat dissipation performance of the car, so the overall water temperature of the car will drop.

Secondly, the water temperature of the engine mainly depends on the wind from the front radiator water tank and the fan. This cycle is a small cycle. Therefore, turning on the warm air is equivalent to increasing the heat dissipation area of the water tank in disguise, increasing the heat exchanged, and naturally lowering the water temperature, which is also the reason why the water temperature of the car turns on the warm air.

In addition, heating the warm air in winter will continue to consume the heat of the engine. If the displacement of the engine is small, the heat generated by the engine operation will not be enough to offset the heat consumed by heating the warm air. Turning on warm air will more easily lead to a rapid drop in water temperature. Of course, it is normal for the water temperature to drop.

Suggestion:

When driving in cold weather, riders can wait until the whole car heats up, and it is best to turn on the warm air after driving at 90 degrees for a certain distance, so that the water temperature will generally become normal and the engine will be better protected.

Remember not to sleep in the car when the warm air is turned on, because the gas in the car is replaced by the air conditioner when the car is driving, and the carbon monoxide generated when the engine is stopped enters the car, which is easy to cause carbon monoxide poisoning in a closed car.
