The full name should be called antifreeze antifreeze coolant, which means there is antifreeze function of the cooling fluid, antifreeze can prevent the cold season parking Splitting coolant radiator and ice 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.
1. What is the use antifreeze
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.

2 antifreeze What is
In addition to selecting the antifreeze, the antifreeze in use, the majority of owners also need to pay attention to the following aspects:
a Note: Try to use the 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: multi antifreeze valid for a two (individual products take longer), confirmed that the product should be added within the validity period; when replacing the old net discharge liquid, clean cooling system after , then replaced with a new liquid;
three Note: avoid watered. Traditional inorganic type 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.
Appearance quality antifreeze should be clear and transparent, and eye-catching color, odor, and some root inferior antifreezeThis does not have anti-freeze and prevent boil function, although some antifreeze freezing point and the boiling point of qualification, but corrosive, water tanks and piping can “bite” riddled with problems, the impact of traffic.
