What is?
The full name should be called antifreeze antifreeze coolant, which means there is antifreeze function of the cooling fluid, antifreeze coolant to prevent freezing during the cold season parking Splitting the heat and frozen engine block, but we have to correct a misunderstanding, not just winter with antifreeze, car maintenance of normal project, each year traveling, the need to replace the engine antifreeze, antifreeze special vehicle replacement frequency is higher .

what’s the use?
1, corrosion protective effect on the components of the cooling system.
2, to prevent scale, to avoid reducing the cooling effect of the radiator.
3, can ensure that the engine operates at a normal temperature range.
Thus, the engine antifreeze must have antifreeze, anti-boil, anti-corrosion, dirt, non-foaming characteristics, is not affected by seasonal and geographical. Among them, freezing and boiling points are basic indicators antifreeze.

Did you know?
In addition to selecting the antifreeze in the antifreeze during use, the majority of owners also note the following aspects:
Note a: to make use ofThe same brand of antifreeze. Different brands antifreeze metal corrosion inhibitor used is not the same, so different brands of antifreeze can not be mixed.
Note II: mostly antifreeze is valid for two years (president of a number of individual products), confirm that the product should be added within the validity period of;
should replace the old net liquid discharge, after the cooling system is clean, then replaced with a new liquid;
three Note: avoid watered.
non-traditional type of antifreeze can not be watered, that would generate precipitation, seriously affect the normal function of the antifreeze.
There are models antifreeze can be watered, but not against too much water.
Note 4: Use of vehicle antifreeze, do not directly supplement the water should be added distilled or deionized water, if there is no condition, add cold water better than tap water added. If the antifreeze due to leakage losses, should be added to the same brand of antifreeze. Antifreeze should be four seasons, summer water service method is unscientific, and it is worth the candle.
Note Five: Some antifreeze stored for one year later, there will be a small amount of flocculent precipitate, this phenomenon is mostly caused by precipitation of the additive, does not have to throw away. If a large number of particle precipitation appears indicating that the antifreeze has changed, we can no longer be used.
Note Six: Another key to select antifreeze is to ensure safety. Senior antifreeze both corrosion, scale, anti-boil, antifreeze, rust and other effects, but also play a very good protection for the tank, it can be used all year round. The appearance of quality antifreeze should be clear and transparent, and eye-catching color, no smell, and some low-quality antifreeze does not have anti-freeze and prevent boil function, although some antifreeze freezing point and the boiling point of qualification, but corrosive, can tanks and piping “bite” riddled with problems, the impact of traffic.
