What do you mean Max is in the car?

Max means "maximum". The max logo on a car is usually on a jar filled with antifreeze. And brake oil from the pressurized oil tank. It means upper limit, that is, don't exceed this scale when adding.

The full name of antifreeze is antifreeze coolant. It has three functions: 1. Prevent the vehicle from freezing when it is not started. Because the antifreeze is in the cylinder, the volume of the liquid will expand when it becomes solid, so it will freeze and rupture the cylinder. 2. After the vehicle is started, cool the engine. Prevent the engine from being damaged due to excessive temperature. 3. Antifreeze also plays a role in controlling corrosion and preventing pipelines from being blocked due to excessive scale. Antifreeze is generally replaced once every two years, about 6W km. If the antifreeze is not replaced for a long time, the quality of the antifreeze will change, thus reducing its internal antirust quality and causing damage to the radiator and pipeline. It will also affect the boiling point and freezing point parameters, antifreeze effect or cooling effect, which is harmful to the engine. Don't wait until the antifreeze turns black before replacing it. The blackening of antifreeze indicates that antifreeze has been seriously deteriorated. The scale has also formed a lot. The pipeline has been damaged. So every time you do maintenance, you can use a freezing point meter to detect the freezing point of antifreeze. If the freezing point is too high, the antifreeze has deteriorated and needs to be replaced.
