Look at mango 130 km. What's wrong with no heating?

Reading Mango 130 km does not give off heat, but there is something wrong with the cooling system of the engine or the control mechanism of the warm air. Automobile warm air circulation is to connect a pipeline in parallel in the small circulation pipeline of engine coolant, which is connected with a warm air water tank, and the blower blows the warm air water tank to generate warm air, which is how the air conditioning 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.

The heater tank is blocked. The structure of the warm air water tank is actually a miniature version of the radiator of the engine water tank, and there are many small cooling pipes in it, which are as easy to block as the radiator of the water tank. After the inside of the warm air water tank is blocked, the coolant flows slowly, the flow becomes smaller, the heat is insufficient, and the air conditioner does not heat.

How to turn on the warm air

Start the engine to warm up first, don't turn on the air conditioner blower directly, wait until the water temperature pointer reaches the middle position, then turn on the air conditioner, set the air circulation to external circulation, and turn off the air conditioner switch. Wait a few minutes, and then change the loop mode to internal loop.
