Before completely replacing the antifreeze, do a comprehensive inspection to see if there are any traces of leakage and cracks in each pipeline, with the focus on the five-way water pipe. If there is leakage in this part, replace the water pipe or re-fix the interface according to the situation.

Drain

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.

New fluid

After draining about 1 hour, add new antifreeze from the water pipe of the water tank (radiator), which is the method to make antifreeze flow into the water tank quickly. Then, add another bucket of antifreeze into the antifreeze tank until the antifreeze tank is almost full, and run for about 10 minutes. Because the cooling system removes some air, the liquid level drops, and then add antifreeze to the oil tank until the highest mark "MAXT" is filled.
