How to distinguish the authenticity of these three common auto parts?
One, glass water
Glass water is a special windshield washer fluid for automobiles. Because it is a poisonous liquid, it is usually blue or green. It's a must-have for everyday driving, providing owners with a great vision and driving safety. Although it may seem inconspicuous, there are many fakes on the market today.
Simple way to identify:
1. The most effective way to judge the authenticity of glass water is to look at its antifreeze performance. You can bring some liquids to freeze. Real glass water is cold-resistant and not so easy to freeze, and inferior products will freeze very quickly.
2. Shake the bottle vigorously to see if there is foam. Usually good glass water foam will be finer and finer.
3. Turn the bottle upside down and see the rise of the internal bubbles to determine the viscosity of the glass water. Usually the slower the rise, the better the viscosity and the higher the quality. You can even feel it on your hands.

Two, antifreeze
Automobile antifreeze mainly has the functions of antifreeze, anticorrosion, antirust, antifouling, antiboiling and so on. Due to the high freezing point of antifreeze in winter in northern regions, the antifreeze ability is often related to its color depth. Some unscrupulous merchants will add pigments to inferior products. These unqualified inferior antifreeze often not only easily lead to pipeline blockage, but also damage the cylinder block. Affects the performance and service life of the car engine, so car owners should purchase with caution.
Simple way to identify:
1. Due to the addition of chemical substances such as industrial methanol to many inferior antifreeze products, the taste is generally pungent, making people dizzy, tearful, and especially volatile, while genuine antifreeze has almost no peculiar smell, and you can smell it a little when you buy it. a bit.
2. Feel whether the antifreeze is astringent and not lubricating with your hands, and also see if its transparency is opaque and turbid. This product is usually of poor quality.
3. This antifreeze can also be identified by freezing, because a good antifreeze is undoubtedly superior in antifreeze and is not easy to freeze.

Three, the spark plug
The spark plug is an important part in the ignition system of the engine, just like the lighter of the engine, it needs to generate sparks to ignite the mixture so that the engine can work normally. However, if the inferior spark plug is replaced by the owner, the electrode may melt and the engine will be damaged after long-term use.
Simple way to identify:
1. First look at the threaded part of the spark plug. Usually this part of inferior products will be rough. In addition, being touched by a car will feel very uncomfortable, and even a little bit sticky, while the genuine product is smoother.
2. The words printed on the spark plug ceramic insulator can be picked out with your fingernails. If it is easy to buckle, the quality is absolutely unacceptable, and the fake part will feel uneven.
