1. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, high water temperature and slow failure of the warm air;
2. The heater water tank and filter are blocked or there is something wrong with the airflow control mechanism;
3. The water pump is damaged, so that the flow through the small warm air water tank is not enough, and the heat does not come up;
4. The thermostat is always on or the thermostat is turned on too early, which leads to the engine water temperature not coming up, which leads to the slow heating of the warm air.
The solution to slow down the heating of automobile warm air is:
1. Replace the air conditioner filter;
2. Replace the hose of the air conditioning system;
3. Clean the conduit of the evaporator;
4. Clean the condenser.
The heat energy of automobile warm air is cooling water. The reason for the slow fever is that the engine has just started and the water temperature is not hot. As long as the water temperature rises to 90 degrees, the heating will be normal. Start the engine to warm up, and then turn on the heating air conditioner after the engine temperature pointer reaches the middle position. At the same time, the air circulation is set to external circulation, so that the cold air in the car is discharged outside the car. After waiting for 2-3 minutes, set the air circulation to internal circulation.
Precautions when turning on the heating Don't sleep in the car: Just like the principle of turning on the air conditioner, when the engine is working, if the fuel is not completely burned, it will produce high concentration of carbon monoxide. When the car is running, the air in the empty car can convection and be replaced by air conditioning equipment, so the concentration of carbon monoxide is very low. Million car purchase subsidy
