The selection method of antifreeze is: 1. Choose the freezing point of the car according to its ambient temperature conditions. Freezing point is an important index of antifreeze, which should be about 10 degrees lower than local environmental conditions in winter. 2. Choose antifreeze according to different requirements of different vehicles; 3. Choose antifreeze with antirust, anticorrosive and descaling capabilities.
The function of automobile antifreeze is: 1, which plays an anti-corrosion protection role for cooling system components; 2, prevent scaling, and avoid reducing the heat dissipation function of the radiator; 3. Ensure that the engine can work within the normal temperature range.
Matters needing attention in using antifreeze are: 1. The liquid level of antifreeze needs to be checked regularly, and it needs to be replenished in time if it is lower than the lower limit; 2. Observe whether there is turbid sediment in antifreeze, and replace it in time if there is turbid substance; 3. Different models of antifreeze have different colors and cannot be mixed; 4. Before entering winter, it is necessary to measure the freezing point of antifreeze to prevent freezing.
