Như các bác cũng đã biết, súc xả dung dịch làm mát xe ô tô theo phương pháp thủ công có nhược điểm là tốn thời gian và khó xả hết dung dịch cũ ra. Em xin hỏi ở SG có chỗ nào có máy súc xả dung dịch làm mát (cooling system flush machine/coolant exchange machine/power flushing machine) không các bác. Đầu tiên phải tháo van hằng nhiệt (thermostat) ra. Đầu ống nối dưới được tháo ra khỏi block động cơ và gắn vào cái máy này, còn 1 ống kia của máy thì gắn vào động cơ. Máy sẽ bơm nước làm sạch hệ thống làm mát theo chiều ngược lại với chiều lưu thông của nước làm mát, sau đó ta cho dung dịch làm mát mới vào, tất cả chỉ trong vòng 15 phút. Em hỏi nhiều gara rồi và họ nói là không có máy này. Cái máy chỉ có 2-3K đô Mẽo thôi mà không ai chịu đầu tư hết

Cooling system power flush and refill
While you can replace old coolant by draining it out and replacing it with fresh coolant, the best way to properly maintain your cooling system is to have the system power flushed. Power flushing will remove all the old coolant and pull out any sediment and scale along with it.
Power flushing requires a special machine that many auto repair shops have for the purpose. The procedure requires that the thermostat is removed, the lower radiator hose is disconnected, and the flush machine is connected in line. The lower hose is connected to the machine and the other hose from the machine is connected to the radiator where the lower hose was disconnected from.
Water, and sometimes, a cleaning agent is pumped through the cooling system in a reverse path from the normal coolant flow. This allows any scale to be loosened and flow out. Once clear water is coming out of the system, the hose is reconnected and a new thermostat is installed. Then the cooling system is refilled with the appropriate amount of antifreeze to bring the coolant to the proper mixture of antifreeze and water. For most vehicles and most climates, the mixture is 50 percent antifreeze and 50 percent water. In colder climates, more antifreeze is used, but must never exceed 75 percent antifreeze. Check your owner's manual for the proper procedures and recommendations for your vehicle.
