The reason why the car warm air is not hot;
1, the cooling system is short of coolant.
Coolant, commonly known as antifreeze, comes from this, and its principle is different from that of household air conditioning heating. Automobile warm air circulation is to connect a pipeline in parallel in the small circulation pipeline of engine coolant, which is connected with a warm air water tank, and the blower blows the warm air water tank to generate warm air, which is how the air conditioning warm air comes from. The lack of coolant in the cooling system is the most common and easily solved fault phenomenon that causes the warm air not to be hot.
2. The heater water tank is blocked
The structure of the warm air water tank is actually a miniature version of the radiator of the engine water tank, and there are many small cooling pipes in it, which are as easy to block as the radiator of the water tank. After the inside of the warm air water tank is blocked, the coolant flows slowly, the flow rate becomes smaller, and the heat is insufficient, so the air conditioner warm air is naturally not hot.

Mistakes in heating air:
1, warm air will increase fuel consumption.
Car heaters and air conditioners use completely different working principles. Car warm air mainly comes from the heat of the water tank. It uses the circulating water of the engine to generate heat, and then the hot air is blown out by the blower, which does not consume oil at all. 2. Turn on the warm air when the ignition switch is turned on.
In winter, the temperature of the water tank is low, and the warm air is turned on as soon as the engine is started, which will inevitably increase the burden on the engine and delay the rise of water temperature. And even if the warm wind is turned on, the cold wind will blow out, and the body feels uncomfortable. Although some car owners understand this truth, it is not correct to turn on the warm air before the water temperature indicator goes out after driving for a period of time.
