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 rate becomes smaller, and the heat is insufficient, so the air conditioner warm air is naturally not hot.
The blockage of warm air tank has no effect on engine heat dissipation. The reason is that the coolant contains too much scale, impurities, flocs and so on. These impurities are caused by careless maintenance. When adding coolant, replace them with water or other brands of coolant. Once the heater box is found to be blocked, the radiator of the engine water tank will also be partially blocked. Clean the inside of the warm air water tank, the inside of the radiator of the water tank and replace all the coolant, so as to completely eradicate the fault.
Extended data:
The cooling system is short of 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, 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. After the coolant is replenished, the warm air tank is filled with boiling coolant, and the warm air will naturally heat up.
