How to choose the most appropriate car parts with the highest cost performance ratio? Here, I recommend the following tips to help you choose the best car parts: Lost parts should be returned.
1. The packaging of the original accessories is generally standardized, with unified standard specifications and clear and regular handwriting, 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 accessories shall be specified with a certain color. In case of other colors, they are fake and inferior parts;
3. Look at the appearance. The printing or casting words and marks on the appearance of the original accessories are clear and regular, while the appearance of the counterfeit products is rough;
4. It is seen that the illegal paint dealer will simply process the waste parts, such as dismantling, assembling, splicing, painting, etc., and then sell them as qualified products to illegally obtain high profits;
5. According to the texture, the materials of the original accessories are qualified according to the design requirements, and the counterfeit products are mostly replaced by cheap and inferior materials;
6. Although the appearance of the product is sometimes good due to poor workmanship, it is easy to have cracks, sand holes, slag inclusions, burrs or bruises due to poor workmanship;
7. If the "stored" auto parts have dry cracks, oxidation, discoloration mirror or aging problems, they may be caused by poor storage environment, long storage time, poor materials, etc;
8. Look at the "engagement". If the rivets of the clutch plate are loose, the brake hose is unglued, the electrical parts are soldered off, and the paper filter element is detached, it cannot be used;
9. The regular parts and components are marked with certain marks, such as timing gear mark, piston top mark and other assembly marks, to ensure the correct installation of the parts, and those that are not can not be purchased;
10. The missing and normal assembly parts must be complete and intact to ensure smooth loading and normal operation. Some small parts on some assemblies are not loaded, which is generally "junk", which makes loading difficult. 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, protective layers are provided before parts leave the factory. For example, bushings, large and small bearing shells, pistons, valves, etc. are generally protected with paraffin to avoid surface damage. If there is no protective layer on the surface of these important accessories, most of them are "junk";
12. Some important parts, especially assemblies, such as carburetors, power distributors, generators, etc., are usually accompanied with instructions and certificates when leaving the factory to guide users in installation, use and maintenance. If they are not, most of them are counterfeit products;
13. When purchasing auto parts according to the specifications, find out the main technical parameters, and the special technology should meet the use requirements. Some fake and shoddy products have the same appearance as the real ones, but they are not suitable for installation. They are either larger or smaller, and are always not satisfied with use, leaving potential accidents.
14. The test report issued by a third party can not only prove the authenticity, but also show the quality.
