Is there any relationship between turning on the heater while driving in winter and reducing antifreeze?
It doesn’t matter.
The oil in the car is a consumable product, as is antifreeze. The full name of antifreeze is called antifreeze coolant. As we all know, it plays the role of cooling and preventing boiling. Since it is a liquid and prevents high temperatures, Then under the influence of high temperature, it will be more or less volatile, so the loss of antifreeze is normal.
The validity period of antifreeze is generally two years. Expired antifreeze will cause cylinder corrosion, and in severe cases, may even cause serious damage to the engine. In addition, the freezing point of antifreeze is generally around -25°C. If you go to a colder place, you need to replace the antifreeze with a lower freezing point.

Causes of air conditioner warm air:
1. The heater water tank is clogged
The structure of the heater water tank is actually The reduced version of the engine water tank radiator has many small heat dissipation pipes inside, which is easy to get clogged inside like the water tank radiator. When the inside of the heater water tank is clogged, the coolant flowing through becomes slower, the flow rate becomes smaller, and the heat is insufficient, so the air conditioner warm air is naturally not hot.
2. Thermostat failure
A common failure of the thermostat is that it cannot be opened, but the reason why the heater is not hot due to thermostat failure is that the thermostat is turned off. If not, it is commonly known as the thermostat is always open. After the thermostat is normally open, the coolant circulates widely from the engine idling. If the water temperature is low for a long time in the northern winter, the air conditioning warm air will naturally not be hot. It can also be clearly seen from the water temperature gauge that the needle is significantly lower than the normal scale.
3. Heating water valve failure
Heating water valve is common in luxury brand models. It is actually an electronically controlled valve. The warm water valve is installed between the water inlet pipe of the heater water tank and the small circulation pipe of the engine. The opening of the valve is controlled by the air conditioning computer, thereby controlling the flow of coolant into the heater water tank, achieving the purpose of more accurately controlling the temperature of the air conditioner warm air.
