Shaanxi automobile Delong k3000 warm air pipe is not hot.

The reason why the hot water pipe of Shaanxi Automobile Delong k3000 heater is not hot is that the cooling system lacks coolant. Coolant, commonly known as antifreeze, comes from this, and its principle is different from that of household air conditioning heating. Automobile warm air circulation is to connect a pipeline in parallel in the small circulation pipeline of engine coolant. The pipeline is connected with a warm air tank, and the blower blows the warm air tank to generate warm air, which is how the air conditioner warm air comes from. The lack of coolant in the cooling system is the most common and easily solved fault phenomenon that causes the warm air not to be hot.
