Hao 336 heating pipe can't reach the heating water tank. What happened?
The thermostat is turned on too early.
Let the cooling system circulate too early, the outside temperature is very low, especially when the car is driving, the cold air will quickly cool the antifreeze, the engine water temperature will not come up, and the warm air will not be hot.
The impeller of the water pump is damaged or lost, so that the flow through the warm air small water tank is not enough and the heat cannot come up. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, high water temperature and not hot warm air.
