The high quality antifreeze is replaced once a year, and those vehicles with short running distance can be replaced every two or 30 thousand kilometers. Some excellent long acting antifreeze liquid, due to the addition of some additives, valid for up to three years.
Attention one
Use the same brand of antifreeze as much as possible. Because different brands of antifreeze liquid used in metal corrosion inhibitors are not the same, after mixing easy to reduce quality, so different brands of antifreeze as far as possible not mixed. The validity of antifreeze is generally for two years (the product of individual time, add some of the president) should confirm whether the products within the validity period; replacement should also put a clean old liquid, the cooling system after cleaning, and then replaced the new antifreeze.
Attention two
Avoid using water. Some of the traditional antifreeze can not be used with water, so easy to precipitate, seriously affect the normal function of antifreeze.
Attention three
The use of antifreeze in the vehicle, do not directly add tap water, should add distilled water or deionized water, if there is no condition, add cold boiling water better than tap water added. If the antifreeze occurs due to leakage loss, the same brand of antifreeze should be added. Antifreeze is a liquid that can be used all the year round.
Attention four
Some antifreeze can be stored for a year, there will be a small amount of flocculent precipitation, this phenomenon is mostly caused by additives precipitation, such antifreeze is not thrown away. Of course, if a large amount of particle precipitation occurs, indicating that the antifreeze has deteriorated, it can no longer be used.
Attention five
Another key to select antifreeze is safety performance. Advanced antifreeze has both antiseptic, anti scaling, anti boiling, anti freezing, anti rust and other functions, but also play a very good role in the protection of the water tank. The appearance of high-quality antifreeze is generally clear and transparent, and has eye-catching color, no smell, and some low-grade antifreeze does not have the function of antifreeze and prevent boil, corrosive, the water tank and pipeline corrosion in a disastrous state, affect the overall safety performance of vehicles.
