During the winter, many car owners will add to the car antifreeze, antifreeze sales Qingdao gradually lower the temperature in recent days into the season. Reporter visited the learned, currently on the market the antifreeze mixed, cottage products co-exist with the so-called "import" cheap antifreeze and even businesses claiming the sales of substandard products. En Rui automotive brake caliper reminded owners, the antifreeze may seem trivial, but the car is great, ranging from clogged pipeline corrosion damage to the engine, so owners should choose a regular antifreeze avoid cheaper plans.
Learned that the uneven quality of the antifreeze market the existing cottage products, there are so-called imported products, prices ranging from three to 40 yuan to several hundred dollars.
Compared to City Auto Parts and roadside auto repair shop, 4S shop of antifreeze relatively regular price is naturally higher. About 100,000 of the cars, for example, only the original antifreeze shall be more than 100 yuan, about 200,000 cars original antifreeze is 130 yuan. , 4S shop mostly original antifreeze and other brands, and charged time charge for.
Vehicle owners how to choose their car antifreeze it? Antifreeze is an essential item for winter car care, winter car failure, largely with antifreeze, therefore, timely inspection and replace the antifreeze is very necessary. We must first understand the the antifreeze characteristics can be the right choice antifreeze. , Antifreeze antifreeze has winter, summer, anti-boil function, and the ability to anti-corrosion, anti-scaling, protect the engine cooling system, to improve the cooling effect, improve engine efficiency. The antifreeze composition generally by the base fluid and additive, the base liquid composition, consisting of water and ethylene glycol or diethylene glycol, additives include anti-rust agents, antifungal agents, pH adjusting agents, anti-foam agents and coloring agents.
In kind, the antifreeze is generally divided into two kinds of concentrated and non-concentrated, non-concentrated antifreeze can not be diluted with water. In addition, the different brands and types of antifreeze applies temperature also vary. Example, a well-known brand of antifreeze freezing point of -46 ° C, -30 ° C and -15 ° C, "In layman's terms, the three temperature represents the minimum withstand the temperature of the freezing point of the antifreeze is in this temperature under before icing. "
Owners can select the appropriate antifreeze according to the location and environment, lower in general, than the local minimum winter temperatures 10 ℃, shall be suitable for the freezing point. Example Qingdao, Qingdao last winter minimum temperature of about -13 ℃, that to suitable the Qingdao owners antifreeze freezing point shall be -23 ° C, so owners can choose antifreeze freezing point below -25 ℃.
Currently on the market many types of antifreeze, the quality is good and bad, there is no formal inspection products tend to have strong corrosive, easy to damage the car's cooling system, some antifreeze will tank corrosion perforation into the engine, cause serious engine failure, so owners must choose the regular brand of antifreeze.
In addition, to remind owners of in and select antifreeze, but also pay attention to the following points:
First of all, try to use the same brand of antifreeze. Different brands of antifreeze production formula different mix between a variety of additives is likely to occur chemical reaction affect the results.
Secondly, most of antifreeze valid for two years, owners should confirm that the product is within the validity period, at the same time must be changed regularly antifreeze added, "generally replaced every two years, ran away car should replace some of the ground. '
Filling antifreeze must first remove the old antifreeze and engine cooling system cleaning to remove accumulated scale engine cooling system Zhongyuan. Adding antifreeze liquid level is generally around plus away from the tank outlet 10mm is appropriate, too much and too little, and are likely to cause cooling system appear hidden.
En Rui automotive brake caliper also reminded owners if it is the year to buy a new car, do not need to replace the antifreeze; if the vehicle has been used for more than two years, you need to replace the antifreeze in a timely manner.
City quality supervision staff to remind consumers, in accordance with state regulations, the antifreeze must have basic information such as the make site, production and sales units must have a business license, regular antifreeze manufacturers more than in adding a coloring agent in antifreeze color looks Refreshing luster, its main ingredient is ethylene glycol, no odor. The main raw material of poor quality antifreeze industrial methanol chemical fusel scraps, corrosive, pungent odor. Consumers to buy the the antifreeze best choice for regular automotive stores or supermarkets, the price is significantly low antifreeze is best not to buy. |
