The blockage of the heater water tank is also a possible reason why the heater is not hot. 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. Clean the inside of the warm air water tank and the radiator of the water tank. The lack of antifreeze in the cooling system is the most common reason why the warm air is not hot. When designing the engine cooling system, engineers will give priority to engine heat dissipation, and then the warm air can work normally.
Extended data:
The usage of small heater water tank of Changan van is introduced as follows:
There are two main reasons why the general car warm air is not hot enough after it is turned on. There is something wrong with the cooling system of the engine or the control mechanism of the warm air, which can't work normally. The owner can check the temperature of the two inlet pipes of the warm air small water tank. If both are hot enough, there is nothing wrong with the heating control mechanism. If they are all cold or hot and cold, there is something wrong with the cooling system.
The cooling system of the engine is blocked by air, which leads to the abnormal operation of the cooling circulation system of the automobile and the problem that the warm air is not hot. If the inlet pipe of the warm air small water tank is hot and the outlet pipe is cold, it means that the small water tank is blocked and needs to be replaced.
