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.
