What's wrong with the warm air in Ou Man?

1, the thermostat has been open or the thermostat has been opened too early, which makes the refrigeration system have a big cycle prematurely and the outside temperature is very low. Especially when the car is running, the cold air will quickly cool the antifreeze, the engine water temperature will not come up, and the warm air will not be hot.

2. The water pump impeller is damaged or lost, resulting in insufficient flow through the small warm air water tank and no heat coming in.

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 neither hot nor cold. If there is air in the cooling system all the time, it may be that the cylinder pad is damaged and the air flows to 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.
