How to identify the authenticity of these three common Petrol Car accessories?

1. Glass of water

Glass water is a windshield washer fluid specially designed for Petrol Car. Because it is a poisonous liquid, it is usually blue or green. It is a must-have for daily driving, which can bring beautiful vision to car owners and ensure driving safety. Although it may seem inconspicuous, there are many fakes on the market now.

①The most effective way to judge the authenticity of glass water is to look at its antifreeze performance. You can bring some liquid to freeze. Real glass water has strong cold resistance and is not easy to freeze, and inferior products will freeze quickly.
② Shake the bottle vigorously to see if there is any foam. Usually the water foam in a good glass will become finer and finer.
③ Turn the bottle upside down and look at the rise of the bubbles inside to determine the viscosity of the glass water. Usually the slower the rise, the better the viscosity and the higher the quality. You can feel it even if you put a little on your hands.
2. Antifreeze
Antifreeze for Petrol Car mainly has the functions of anti-freeze, anti-corrosion, anti-rust, anti-scaling, and anti-boiling. Since the freezing point of antifreeze in northern areas is higher in winter, its antifreeze ability is often related to its color depth. Some unscrupulous merchants will add pigments to inferior products. These unqualified and inferior antifreeze often not only easily lead to pipe blockage, but also damage the cylinder block. Affects the performance and service life of Roewe Car engines, so car owners should purchase with caution.
① Because many low-quality antifreeze products add industrial methanol and other chemicals, their smell is generally pungent, making people dizzy and tearful, and they are particularly easy to evaporate. However, genuine antifreeze has almost no odor, so you can smell it a little when buying it. .
②Feel the antifreeze with your hands to see if it feels astringent and not lubricated, and also see if its transparency is opaque and turbid. This product is usually of poor quality.
③ This kind of antifreeze can also be identified by freezing, because a good antifreeze is undoubtedly superior in antifreeze and is not easy to freeze.
3. Spark plug
The spark plug is an important component in the engine ignition system. Just like the engine lighter, it needs to generate sparks to ignite the mixture so that the engine can work properly. However, if inferior spark plugs are replaced by car owners, the electrodes may melt and the engine will be damaged after long-term use.
①First look at the threaded part of the spark plug. Usually this part of inferior products will be rough. In addition, if it is hit by a car, it will feel very rough and even a bit prickly, while the original one is smoother.
② You can use your nails to pick out the words printed on the ceramic insulator of the spark plug. If it is easy to buckle, the quality is absolutely unacceptable, and the fake part will feel uneven to the touch.
