Volkswagen Touran1.6,2015 heater water tank pipe 22mm. Moreover, the engine cooling system has air resistance, which leads to poor circulation of the cooling system, resulting in high water temperature and no warm air. In addition, if there is gas in the cooling system all the time, it is likely that the cylinder gasket is damaged and the gas leaks into the cooling system; If the inlet pipe of the small heating tank is very hot and the outlet pipe is very cold, this situation should be that the small heating tank is blocked and should be replaced.
Precautions:
The warm air of the car is blown into the cab by the blower. If the air volume is insufficient or the distribution of cold and hot air is uneven, the heat of the warm air tank cannot be radiated, which will also cause the temperature of the warm air not to rise. At this point, first check whether the filter element is dirty or blocked, clean it, and replace it in time if necessary.
