Automobile warm air not hot cause elimination method and solution
In the winter season, the weather gets cold, I believe that all the owners will open the warm air in the car to keep the temperature in the car warm, but some owners reflect their car warm air is not hot, it is a headache, the following can understand some of the reasons for the elimination of hot car warm air and solutions.
There are two main reasons why the warm air of general cars is not hot enough after opening. There are problems with the cooling system of the engine or the control mechanism parts of the warm air, which are not caused by normal work. The owner can check the temperature of the two inlet pipes of the warm air small water tank. If the temperature is hot enough, it shows that there is no problem with the heating risk control mechanism. If it is cold or one hot and one cold, it is a problem with the cooling system.
And the engine cooling system problems may be caused by:
1. The cooling system of the engine is affected by the air resistance, resulting in the normal operation of the cooling circulation system of the car, which leads to the problem that the warm air is not hot. If the warm air small water tank is hot in the inlet pipe, and the outlet pipe is cold, the small water tank is blocked and needs to be replaced.
2, the vehicle pump impeller is damaged or lost, resulting in the reduction of water flow through the water tank, resulting in the warm air is not hot, the need to replace a new pump impeller.
3. It may also be that the thermostat is always open or opened prematurely, causing the cooling system to circulate in advance, and the external temperature of the vehicle is low, and the external cold wind will cool the antifreeze rapidly, leading to the temperature rise of the water tank is not enough, and the warm wind is not hot enough. The thermostat needs to be adjusted or repaired.
The reason for the problem of the warm air control mechanism parts may be the blockage of the filter, so that the air volume of the blower blowing into the car is not enough or the distribution of cold and hot air is not reasonable. At the same time, it is necessary to check whether each gear of the blower can reach enough speed, and check whether the control flap of the warm and cold air falls off. It is necessary to maintain and deal with it in time.
You owners in the winter want to let the car temperature quickly warm up, you can try a small technique. It is to start the engine to preheat first, rather than directly turn on the air conditioning blower, wait for the water temperature pointer to reach the middle position and then turn on the warm air conditioning, set the air circulation to external circulation, also turn off the A/C switch, wait for A few minutes before changing the circulation mode to internal circulation.
