How does the car heater work?
According to the types of heat sources, automobile heating systems are mainly divided into two types: one is to use engine coolant as the heat source (currently used by most vehicles), and the other is to use fuel as the heat source (used by a few middle and high-class vehicles). When the engine coolant temperature is high, the coolant flows through the heat exchanger in the heating system (generally referred to as the small heater tank), and the air sent by the blower exchanges heat with the engine coolant. After being heated, the air is sent into the car by the blower through various air outlets.
The heat source we know is the principle of heating by using the heat of coolant, so we should first check whether the coolant is enough. If there is a lack of coolant, the heating effect of the air conditioner will be poor.
You also need to check whether the cooling fan is working properly. If the cooling fan rotates frequently, the water temperature cannot rise, and the heating effect of the air conditioner will become worse.
The blockage or leakage of the warm air tank will also lead to poor heating effect or even no heating.
