Where and how much antifreeze should be added?

Coolant can not only be used in winter, but also has the functions of antifreeze, cooling, corrosion prevention and scale prevention. The most important thing is anti-freezing and cooling, which can not only ensure the normal use of the car in cold climate without freezing, but also cool the engine running at high temperature. You can't add too much or too little coolant, so how much coolant is appropriate? Most coolant tanks basically have water level scales, the highest water level and the lowest water level. Most people advocate an increase of about 4 liters, which should be adjusted according to the actual situation of the car. Too little automobile coolant will affect the engine or the frost crack of the water tank, leading to engine failure. It is recommended to add most of the coolant to the position between the highest water level and the lowest water level of the coolant tank. If there is no water mark, raise it a little along the center line of the kettle. If it is added too much, it may overflow, and the coolant is corrosive, which may cause certain corrosion to the rubber parts in the car. A small amount of additives will affect the engine or water tank to freeze or even crack in cold climate, which will not achieve sufficient cooling effect and lead to engine failure.
