Second, drainage: drain the old antifreeze, and then clean the liquid channel with clean water. Add clear water to the antifreeze replenishment tank, then inject clear water into the tank to make the clear water continuously flow through the engine cooling system, and then idle for 3 to 5 minutes to circulate water. 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.
Third, change the new liquid: after about 1 hour, add new antifreeze from the water pipe of the water tank (radiator), which is the way to make the antifreeze flow into the water tank quickly. Then add a bucket of antifreeze to the antifreeze tank until the antifreeze tank is almost full, and take a taxi for about 10 minutes. At this time, due to the exclusion of some air, the liquid level of the cooling system drops, and then antifreeze is added and the storage tank is filled.
