How to troubleshoot the reason why the car heater is not hot and how to solve it
In the winter season, the weather becomes cold. I believe that all car owners will turn on the warm air in the car to keep the temperature in the car warm. However, some car owners have reported that their car is not hot, which is a headache. Let's take a look at some troubleshooting methods and solutions for the reasons why the car's warm air is not hot.
Generally, there are two main reasons why the heater of a car is not hot enough after it is turned on. The cooling system of the engine or the components of the heater control mechanism have problems and are not working properly. The owner can check the temperature of the two inlet pipes of the small heater water tank. If the temperature is hot enough, it indicates that there is no problem with the heater control mechanism. If it is cold or hot and cold, there is a problem with the cooling system.
The reason for the problem of the engine cooling system may be:
1. The cooling system of the engine is air-blocked and the cooling circulation system of the car does not operate normally, which leads to the problem that the warm air is not hot. If the small water tank of the warm air is hot in the inlet pipe and the outlet pipe is cold, the small water tank is blocked and needs to be carried out. replace.
2. The impeller of the water pump of the vehicle is damaged or lost, which reduces the amount of water flowing in the water tank, which causes the warm air to be not hot, and the impeller of the water pump needs to be replaced.
3. It is also possible that the thermostat has been turned on all the time or turned on prematurely, causing the cooling system to circulate in advance, and the outside temperature of the vehicle is low, the outside cold wind will quickly cool the antifreeze, resulting in insufficient temperature rise of the water tank and insufficient warm air. The thermostat needs to be adjusted or repaired.
The cause of the problem with the components of the warm air control mechanism may be that the filter is clogged, which makes the amount of air blown into the car by the blower insufficient or the distribution of cold and hot air is unreasonable. At the same time, check whether the various gears of the blower can reach sufficient speed, check whether the control flap of the warm and cold air has fallen off, and repair it in time.
Every car owner can try a little trick if you want to make the temperature in the car warm up quickly in winter. It is to start the engine to warm up first, instead of directly turning on the air conditioner blower, wait for the water temperature pointer to reach the middle position, then turn on the heater air conditioner, set the air circulation to external circulation, and also turn off the A/C switch. The circulation mode is changed to inner circulation.
