How to use cleaning agent for automobile water tank

1. After the engine stops, add cleaning agent and start the engine to run at idle speed 10- 15 minutes. Turn off the engine, drain the sewage from the water tank, and then clean the water tank with clean water. Generally, there is one bottle for small cars and two bottles for large cars. 2. Add new water from the water pipe of the water tank (radiator), which is the way to make antifreeze flow into the water tank quickly. Then, add another bucket of water from the water tank to the antifreeze tank until the antifreeze tank is almost full, and then drive for about 10 minutes. At this time, due to the partial removal of air, the liquid level of the cooling system has dropped, and then antifreeze is added and filled to the highest mark of the liquid storage tank. 3. Empty the old water tank, and then clean the liquid channel with clean water. Add clean water to the water tank, then inject clean water into the tank to make the clean water continuously flow through the engine cooling system, and then idle for 3 to 5 minutes to make the water circulate. The water in the pitcher is a little pink at first. Continue to inject clean water until the water becomes clean. Be careful not to forget to remove the heating water pipe and clean the water in the heating water tank.
