When designing the engine cooling system, the engine heat dissipation will be given priority, and then the warm air can work normally. When the coolant is insufficient, the coolant will first circulate in the engine. At this time, there is no water in the warm air circulation pipeline, and most of the warm air tank is gas. At this time, the air conditioning warm air is naturally not hot. After adding antifreeze, the warm air tank is filled with boiling coolant, and the warm air will naturally heat up.

Things to check when using cars in winter:
1, check antifreeze.
Antifreeze is called antifreeze coolant. Many people think that antifreeze is only used in winter. In fact, antifreeze is essential for the engine, and its main function is to cool the engine. It circulates in the engine cooling system, taking away the high-temperature heat generated during the engine operation, and making the engine run at the normal working temperature.
2, check or replace the tire
As the temperature drops, the tire will become hard and brittle, and the friction coefficient with the road surface will decrease, making it easier to puncture and puncture the tire than in other seasons.
In winter, the tires of vehicles should be checked more frequently than usual. Need to remind everyone that the tire life is generally 3-5 years, about 50,000 kilometers. If there are many small cracks on the sidewall, it means that the tire is seriously aging and needs to be replaced in time.
3. Is the vehicle losing control?
Deviation is also a very common and easily overlooked problem. Many friends don't care about this small deviation, but in winter, due to the influence of temperature, the road surface and car condition will decline, and the usual small problems will be amplified at this time, bringing more serious safety hazards.
