In the upper right corner of the engine compartment, the water tank is used to hold automobile coolant. Tap water or mineral water cannot be added directly. If coolant is added, the same type of coolant should be added. If the models are different, they should be replaced, and they cannot be mixed. Water tank is an important part of water-cooled engine, which can absorb the heat in the cylinder. The engine is cooled by the night circulation of cooling water, and the working temperature of the engine is not too high by using the thermal conductivity of water and the convection of large area fins.
Although the colors of different brands of coolant look different, these colors are actually formed by adding dyes in order to distinguish coolant from other liquids.
However, different coolants have different compositions. Some use ethylene glycol and some add phosphate, so different coolants can't be mixed, otherwise it will be corrosive and harmful to the engine. Automobile coolant should be added in time, and antifreeze coolant should be selected to cope with the low temperature weather in winter.
