It is necessary to remove two pipes from the heating water pipe and blow through the heating water tank. This method is simple, but it can only be used when the inside of the water tank is blocked by softened sludge. It is inevitable that cars will produce exhaust gas after running for a long time, so riders should pay attention to car maintenance at ordinary times to avoid the water tank and other parts being blocked by waste.
In addition, a simple way to solve the blockage of the warm air tank is to find a washing station, and then let the repairman remove the inlet and outlet pipes of the warm air tank, and then wash them back and forth with the water gun of the car wash until the washed water becomes clear.
If there is a special scale remover, you can also take off the original antifreeze and use it with the scale remover, and then add a new coolant when it is used up. If the above methods can't be solved, you can only change to a new heater tank.
Matters needing attention in the use and maintenance of automobile water tank;
1. Hard water should be softened before use to avoid internal blockage and scaling of radiator. When using antifreeze, in order to prevent the radiator from being corroded, we should choose high-quality long-term antirust antifreeze produced by regular manufacturers, which meets the national standards.
2. Check the water level at any time in daily use, and then add water after stopping the machine to cool down. When adding water, slowly open the cover of the water tank, and keep your body away from the water inlet of the water tank as far as possible to prevent high-pressure steam from spraying from the water inlet.
