Life skills to teach you to identify genuine and fake auto parts
In this age of car proliferation, it is not really possible to have any knowledge related to automobiles, such as the maintenance and repair of vehicles, the cleaning and replacement of spare Parts, etc. In particular, the replacement of spare parts, if you encounter shoddy, real accessories, it is still very dangerous, fake pit people probably say that.
One: glass water
The glassy water is blue liquid, which is mainly used to clean the front and rear windshields of the vehicle. It is a consumable product. The use frequency of windy and rainy weather is relatively high, and it will be completed within a few days. And the major supermarkets, auto repair shops have sold, then the problem has come, the glass of water on the market counterfeit, although the price is not expensive, the problem is false glass water is easy to block the nozzle, and the glass is not clean.
Identification method:
1. If you can't unscrew the bottle cap, shake it vigorously to see how much bubbles are in the bottle. The richer the bubble of glass water is, the stronger the ability to decontaminate the glue.
2, can be used to open the smell, to see if there is the taste of alcohol, in general, the authentic glass of water in the composition there will be more or less there is ethanol, so there will be the taste of alcohol.
3, to find a container, go to the point and put it down in the refrigerator, in general, the freezing point of glass water is very low, after the next day out, there is no adhesion phenomenon, the fluidity of the liquid is very smooth, indicating that this glass of water is no problem Because of its low freezing point, it has very good cold resistance.
II: Motor oil
The role of oil is to reduce the friction between the metal, improve work efficiency and increase the life of the engine. If the engine is the heart, then the oil is equivalent to blood, if the blood is false, the problem is big.
Identification method:
1, see, mainly to see the color, at room temperature, the color of genuine oil than the fake oil to a lot deeper, and there is no impurity inside.
2, smell, smell the smell of oil through the nose, will find that the authentic engine oil is almost no sensitive taste, similar to a touch of fragrance, while the fake motor oil has a clear smell of gasoline.
3, frozen, this method is similar to glass water inspection, take a little oil to a paper cup, and then place it in the refrigerator at minus 15 degrees Celsius, frozen for 48 hours, genuine oil will show good low temperature fluidity, while transparency and There was no significant change in color, while the fake motor oil appeared slightly viscous and turbid.
Three: brake pads
Brake pads are an important accessory. A fake brake pad will not only fail to hold the car, but it will also threaten our lives. It is not unreasonable that the poor should not be underpowered. In daily driving, light brakes are accompanied by the sound of “Iron Iron†(alarm film), and the braking distance is significantly longer, which means that the brake pads will be more slid. Generally speaking, the driving distance will be 60,000 kilometers. It is necessary to consider replacing them, and even if they do not change, they must be checked.
Identification method:
1, to see the weight, the weight of the high-quality brake pads is much heavier than the fake ones. You can use the old brake pads to weigh it. If the new weight is heavy, there is no problem.
2, look at the packaging, genuine brake pads packaging exquisite, and are equipped with a certificate. Then look at the brake pad for the presence of an intermediate diversion groove. The function of this groove is to expel the rubbing debris and ensure that the work surface is tightly bound.
3, look at the location of the alarm film is not standard, this is a process problem, if even this can not do well, then you directly give up this fake it.
