According to each manufacturer's model, antifreeze replacement intervals will vary. Generally speaking, the replacement interval of powerful coolant is 8 years or 160,000 kilometers, and the second replacement interval is halved, i.e. 4 years or 80,000 kilometers. In addition to following the cycle, we also need to regularly observe the level, if the coolant is insufficient should be added immediately to avoid safety hazards.

The role of coolant is: 1, the cooling system components to play a role in anti-corrosion protection; 2, to prevent scale, to avoid reducing the role of radiator cooling; 3, to ensure that the engine can work within the normal temperature range.
