Land Rover found four reasons why warm air is not hot.

Land Rover found four reasons why the warm air is not hot: 1, the thermostat is always on or the thermostat is turned on too early, which makes the cooling system carry out a large cycle too early, and the outside temperature is very low, especially when the car is driving, the cold air cools the antifreeze quickly, the engine water temperature does not come up, and the warm air will not be hot; 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 does not come up; 3. If the inlet pipe of the small warm air tank is very hot and the outlet pipe is very cold, this situation should be that the small warm air tank is blocked, and the small warm air tank should be replaced.
