How much does it cost to change a heating box?

The warm water tank is blocked. You can blow it yourself with a high-pressure air gun to see if it can be unblocked. Remove two pipes from the warm water pipe and then connect them to the warm water tank for ventilation. Although this method is simple, it can only be used when the water tank is blocked by softened sludge. Encourage riders to clean the warm water tank regularly on weekdays. If it is broken, a new warm water tank needs to be replaced, and 500 yuan is needed.

In addition, riders can find a parking lot to clean their cars, and then ask the repairman to remove the inlet and outlet pipes of the car's warm water tank, and then wash the car back and forth with a high-pressure water gun until the washed water becomes clear water. If there is a special scale remover, you can drain the original cooling liquid of the car first, and then clean it with the scale remover. After cleaning, add new coolant.

1. Prepare tank cleaner, coolant, gloves and carp tongs. Open the buckle of sewer pipe with carp pliers, then unscrew the inlet pipe of warm water tank, and then open the pipe after the buckle is opened.

2. Insert the nozzle of the high-pressure air pump into the water inlet pipe of the warm water tank, turn on the air pump, and high-pressure air will be blown into the whole circulating waterway, including the warm water tank pipeline. With the entry of high-pressure air, the remaining dirty water in the water tank will also be blown out.

3. Add cleaning agent, fill the water tank with tap water, start the car to rotate for 30 minutes, and turn on the warm air. That's it. Add water three times. Before each water change, dredge the pipeline with high-pressure gas. Every 10 minute, the color of the discharged water becomes clear. Finally, adding coolant is enough.
