Causes and solutions of car fever

The reason why cars don't heat is that there is not enough air-conditioning refrigerant, so it is necessary to add air-conditioning refrigerant.

The reason why the car is not hot may be that the heating box is blocked, or it may be the influence of insufficient antifreeze in the cooling system. These factors related to the heater not heating need to be detected one by one. After the engine is started, the temperature of engine oil and antifreeze will continue to rise, and at the same time, the residual heat generated by the engine will be taken away. The antifreeze will flow through the heat exchanger in the heating system to heat the air, and then it will be sent into the car by the blower. This is the principle of air conditioning heating that is often encountered.

Another reason is the lack of antifreeze in the cooling system, which is also the most common phenomenon that the warm air is not hot. If you get out of this situation, just add antifreeze.

Check the vehicle

If the vehicle's warm air is not hot, it is probably affected by the blockage of the warm air tank. There are many small pipes inside the warm air tank, which are very easy to cause blockage during work. After the inside of the warm air tank is blocked, the antifreeze flowing through it slows down. In this state, the warm air of the air conditioner will not be very hot.

Turning on the air conditioner without preheating will affect the efficiency of the engine. When the vehicle is cold started, the temperature of the engine is very low. Suddenly turning on the heating will not only increase the load of the engine, but also affect the fuel consumption of the vehicle.
