How to disassemble the water tank of Audi q5 heater?

Disassembly of Audi q5 warm water tank. First, remove the connector behind the blower motor, separate the cable holder on the left side of the heater, and remove the screw on the terminal.

Then, after removing the instrument assembly, you can see the heater fan, remove the screw of the heater fan, and then remove the heater box.

The function of the warm water tank is to provide warm air to the car, raise the temperature inside the car and remove the frost and fog on the window glass. Its working principle is that when the engine is working, the coolant heated by the engine cylinder at high temperature enters the heat exchanger through the water inlet pipe under the action of the water pump of the engine cooling system, and the heat emitted by the coolant is sent to the engine room or windshield by the air blown by the blower, so that the temperature in the engine room is raised and defrosted.

The heat source comes from the engine coolant, and the water heating system is mostly used to heat cars, trucks and buses with low 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 adjustable speed DC motor and squirrel cage fan, which blows cold air to the heater and sends it into the car after heating. Adjusting the speed of the motor can adjust the air supply of the car.

The car warm air blows the residual heat of the engine into the car through the blower. When the engine was just started, it didn't generate enough temperature. In this case, turning on the warm air not only has no effect, but also increases the discharge capacity of the battery.
