How To Choose

What are the good ways to buy auto parts? How can we buy the most suitable and cost-effective auto parts? Here, I recommend the following skills to help you choose the best auto parts: the lost parts should be returned and replaced.

1. Looking at the packaging, the packaging of original accessories is generally standardized, unified standard specifications, clear and formal printing, while the packaging and printing of counterfeit products are relatively poor, and it is often easy to find flaws in the packaging;

2. According to the color, the surface of some original parts shall be specified with a certain color. In case of other colors, they are fake and shoddy parts;

3. Look at the appearance, the printing or casting words and marks on the appearance of original accessories are clear and formal, while the appearance of counterfeit products is rough;

4. Look at the illegal businessmen who simply process waste parts, such as disassembly, assembly, assembly, painting, etc., and then sell them as qualified products to illegally obtain high profits;

5. According to the texture, the materials of original accessories are qualified materials according to the design requirements, and most counterfeit products are replaced by cheap and inferior materials;

6. The appearance of products with poor workmanship is sometimes good, but due to poor manufacturing technology, cracks, sand holes, slag inclusions, burrs or bumps are easy to occur;

7. Look at the "stored" auto parts. If there are problems such as dry crack, oxidation, discoloration mirror or aging, it may be caused by poor environment, long storage time, poor material itself and so on;

8. Look at the "engagement". If the rivets of the clutch plate are loose, the brake hose is degummed, the joints of electrical parts are desoldered, and the joints of paper filter elements are separated, it cannot be used;

9. Look at the marks. Some regular parts are marked with some marks, such as timing gear mark, piston top mark and other assembly marks, which are used to ensure the correct installation of parts. If there is no part, you can't buy it;

10. In order to ensure smooth loading and normal operation, the normal assembly components must be complete and intact. Individual small parts on some assemblies are missing, which are generally "parallel goods", which makes it difficult to load. The whole assembly parts are often scrapped due to the shortage of individual small parts;

11. Look at the protective layer. In order to facilitate storage and prevent parts from bumping, parts are provided with protective layers before leaving the factory. For example, bushings, large and small bearing shells, pistons and valves are generally protected with paraffin to avoid surface damage. If there is no protective layer on the surface of these important accessories, they are mostly "parallel goods";

12. Some important parts, especially assemblies, such as carburetors, distributors, generators, etc., are generally delivered with instructions and certificates to guide users in installation, use and maintenance. If they are not, they are mostly fake and shoddy products;

13. When purchasing auto parts according to the specifications, find out the main technical parameters, and the special technology shall meet the use requirements. The appearance of some fake and shoddy products is almost the same as that of the real products, but it is not suitable to install them. Either they are larger or smaller, they are always dissatisfied with their use, leaving hidden dangers of accidents.

14. The test report issued by the third party can not only prove the authenticity, but also show its quality.
