What is the optimal position for car antifreeze?

It is advisable to fill the car antifreeze to the midpoint between the upper (MAX) and lower (MIN) marks on the reservoir. The method for replacing antifreeze is as follows: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way water pipe. Antifreeze flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any leakage of antifreeze in this section, replace the water pipe or re-secure the connection as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue filling it until water continuously flows through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir may appear slightly pink. Continue adding clean water until the outflowing water is clear. Note: Remember to disconnect the heater hose and drain the water from the heater core. After draining for about an hour, add the new antifreeze through the radiator hose. Then, pour another container of antifreeze into the antifreeze reservoir until it is nearly full. Start the car and let it run for about 10 minutes. During this time, the coolant level will drop as some air is expelled from the cooling system. Add more antifreeze until the level reaches the "MAX" mark on the reservoir.
