Golf 6 Why is the warm air not hot?

The water pump or cooling loop of Pacific Auto Network is blocked by air, which leads to problems in the engine cooling system and the coolant cannot be circulated. Naturally, the heated coolant can't be sent into the warm air tank, resulting in the warm air not being hot. Damage to the impeller of the vehicle water pump will reduce the amount of water in the water tank, thus causing the warm air not to be hot.

The filter of automobile air conditioner is blocked, and the parts of the control mechanism of warm air have problems, which makes the air volume blown into the car by the blower insufficient, or the distribution of cold and hot air is unreasonable, resulting in the phenomenon that the warm air is not hot. Some cars will also be equipped with a warm air water valve to cut off the coolant circulation of the warm air water tank and reduce unnecessary heat loss when the warm air is not used. If the heater water valve is damaged, the coolant may not enter the heater water tank, resulting in the heater not being hot.

If the thermostat of a car is always on or opened too early, the cooling system will circulate ahead of schedule, and the temperature outside the car will be low, and the cold air outside will quickly cool the antifreeze, resulting in insufficient temperature rise of the water tank and insufficient warm air, so it is necessary to adjust or maintain the thermostat.
