After the instrument assembly was removed, the whole picture of the heater was leaked. The heater is connected with three screws. Remove the upper one first, and then remove the other two screws. Then remove the water pipe connected to the heater water tank. Better take out the warm air tank.
Function of hot air tank
The function of the warm air tank is to provide heating for the car, raise the temperature inside the car and remove the frost and fog on the window glass. When the engine works, the coolant heated by the high temperature of the engine cylinder is under the action of the water pump of the engine cooling system.
It enters the heat exchanger through the water inlet pipe, and the air blown out by the blower sends the heat emitted by the cooling liquid to the carriage or windshield to raise the temperature in the carriage and defrost it.
The heat source comes from the engine coolant, and the water heating system is mostly used in cars, trucks and buses with low heating requirements. Water heating and warm air system is mainly composed of heater, hot water regulating valve, blower and control panel.
The blower is composed of a speed-adjustable DC motor and a squirrel-cage fan, and its function is to blow cold air to the heater, and then the cold air is heated and sent into the car.
