How to operate the Touareg heater
Touareg (check transaction price | model details) operating steps for using the heater: 1. About 8-15 minutes after starting the car, the water temperature rises to normal temperature, at this time you can turn on the heater (i.e. water When the temperature rises to the middle); 2. Adjust the air conditioning circulation mode to indoor circulation; 3. Enter the warm air mode, some vehicles are in the red area, and some vehicles are in the sun state; 4. Turn on the air conditioner (do not turn on the AC switch), because Warm air uses the heat cycle of the car itself to save energy.
The reasons why the vehicle heating system is not hot can be divided into two aspects: one is caused by the engine cooling system, and the other is caused by poor working of the heating control mechanism. When repairing, we must first determine which cause is the cause, and then perform corresponding repairs.
The method of identification is very simple: look at the temperature of the two water inlet pipes of the small warm air water tank. If both pipes are hot enough, it means there is a problem with the air volume control mechanism. On the contrary, if both water pipes are cold, Or if one is hot and the other is cold, it means there is a problem with the cooling system.
Possible problems in the cooling system are:
1. The thermostat is always open or the thermostat is opened too early, causing the cooling system to undergo a large cycle prematurely, and the external temperature It is very low, especially when the car is running, the cold air will quickly cool down the antifreeze, the engine water temperature will not rise, and the warm air will not heat up.
2. The water pump impeller is damaged, causing insufficient flow through the small warm air water tank and preventing heat from coming up.
3. There is air blockage in the engine cooling system. The air blockage leads to poor circulation of the cooling system, causing high water temperature and low heating of the warm air. If there is always air in the cooling system, it is likely that the cylinder gasket is damaged and air is flowing into the cooling system; if the water inlet pipe of the small heater water tank is very hot and the water outlet pipe is cold, this situation should be that the small heater water tank is blocked. , the small heater water tank should be replaced.
