As an important means of transportation for our daily travel, automobiles have greatly facilitated our lives. In addition to human factors, the impact of car life, accessories are also an important part of a good horse with a good saddle to play its strength, if you use the inferior accessories, not only do not save money, and sometimes also endanger the driver s life.
A: The glass water glass is a special tool used to clean the front and rear windshields of cars. It is generally blue liquid. When the line of sight is blurred, dial in the lever on the right side of the steering wheel and the glass water will wipe the glass with the wiper.
Glass water is a consumable product, especially in windy and rainy weather, and it is used at a high frequency. It takes a few days to make up for it. This item is also very good to buy, the general supermarket, street auto repair shop has sold. However, there is a very important problem. The glass-water fakes on the market are flooding. Although the prices are not expensive, the problem is that false glass water can easily block the nozzles and the glass is not clean.
How to identify it? The first is to find a container, go to a point and put it down in the refrigerator. Generally speaking, the freezing point of glass water is very low. After the second day, it is not sticky. The fluidity of the liquid is very smooth, indicating that this glass of water is not a problem. of.
Then smell it to see if there is any taste of alcohol. In general, genuine glass water has more or less ethyl alcohol in the ingredients because it has a low freezing point and good cold resistance.
If you can't unscrew the cap, you can shake it vigorously to see how much bubbles are in the bottle. The richer the glass foam is, the stronger the decontamination ability is.
Second: The engine oil is equivalent to the blood of the engine. They reduce the friction between metals, increase work efficiency and increase the life of the engine.
In general, there are three steps to distinguish between true and false oils.
A look is mainly to see the color, in the normal temperature state, the color of the authentic engine oil should be much deeper than the fake motor oil, and there is no impurity inside.
Both heard the smell of oil through the nose and found that the genuine engine oil had almost no sensitive taste, similar to the faint fragrance, while the fake motor oil had obvious irritating gas smell.
The method of three freezes is similar to that of glass water. Take a little oil into a paper cup and place it in a refrigerator at minus 15 degrees Celsius. After freezing for 48 hours, the genuine oil will show good low temperature fluidity, and the transparency and color are not. Obvious changes, while the fake motor oil will appear slightly viscous, and appear turbid state.
Three: Many of the brake pads are used to buying maintenance materials after going out of the insurance to go to some maintenance shops for maintenance. The brake pads are an important accessory. The fake brake pads not only fail to stop the car, but also threaten our lives and the poor. It is not unreasonable that nothing can be done without impoverishment.
If, in daily driving, the brakes are lightly accompanied by the sound of “iron-iron-iron†(alarm film), the braking distance will be significantly longer, which means that the brake pads will be more slid. Generally, the driving speed is 60,000. About a kilometer will consider replacement, even if it does not have to be replaced.
To select a good brake pad, the first is to look at the weight. The weight of the high-quality brake pad is much heavier than the fake one. You can use the old brake pad to weigh it. If the new weight is heavy, there is no problem.
Followed by the packaging, genuine brake pads are exquisitely packaged, and all have 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 face is tightly bound.
Finally, we must take a look. The position of the alarm film is not standard. This is a technical problem. If you can't even do this, then you can directly give up this fake product.
These are some simple ways to distinguish between true and false. In fact, the easiest way is to buy in the 4S shop. Although it is more expensive, the shopkeeper can guarantee your quality. Even if a problem occurs, it is very convenient to make a claim. Do not try to smash sesame but lose watermelon.
