Sagitar warm air is not hot. What happened?
The heating box is blocked and the cooling system is short of coolant, which are two reasons.
The blockage of the heater water tank will lead to the slow flow of coolant through it and insufficient heat, which will lead to the phenomenon that the air conditioner heater is not hot and needs to be cleaned in time.
Insufficient coolant in the cooling system will also lead to the phenomenon that the warm air is not hot, which is also a common fault of the warm air in the daily car use process.
Extended data:
The solution to the problem that the automobile warm air is not heated;
1, the thermostat is always on or the thermostat is turned on too early, which causes the cooling system to make a big cycle prematurely, and the outside temperature is very low, especially when the car is driving, the cold air quickly cools the antifreeze, the engine water temperature does not rise, and the warm air does not heat up.
2. The water pump impeller is damaged or lost, so that the flow through the warm air small water tank is not enough, and the heat can't come up.
3. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and lukewarm air. If there is gas in the cooling system all the time, it is likely that the cylinder pad is damaged and the gas leaks into the cooling system; If the inlet pipe of the small heating tank is very hot and the outlet pipe is very cold, this situation should be that the small heating tank is blocked and should be replaced.
