Coolant, as the name implies, is used for cooling, can be antifreeze, can also be purified water. Any liquid that has a cooling effect can be called a coolant. But antifreeze prevents freezing in the first place, and it also has a cooling effect. The antifreeze and water on the car are called coolant. So the coolant includes but is not limited to antifreeze, antifreeze is not only cooling, the two can not be equal.

The freezing point of general antifreeze should be below minus 35 degrees Celsius. Because this is below this temperature, it will be relatively large oil, oil large antifreeze is not easy to corrosion engine, will not block the water channel inside the tank.

And our northeast region should choose minus 45 degrees Celsius antifreeze, because the choice of -45 degrees Celsius antifreeze, only the environmental temperature is lower than -45 degrees Celsius will freeze. Your car mainly according to their own environment to choose suitable car coolant oh。
