How to choose the most cost-effective auto parts, here, I recommend the following tips to help you choose the best auto parts: the loss should be replaced.

1, the original factory packaging accessories packaging is compared commonly specification, standard specification, printing clear, formal and counterfeit products packaging and printing is poor, often can easily find the flaw from the packaging;

2. Look at the color of some parts of the original factory, and if it meets other colors, it will be fake and shoddy.

3. Look at the appearance of the original parts of the factory.

4. Look at the painting of illegal dealers to make the waste parts by simple processing, such as dismantling, assembling, assembling, scraping, painting and other processing, and then passing off as qualified products for sale, illegally obtaining high profits;

5. The materials of the original parts of the material are qualified materials according to the design requirements, and the fake products are mainly used for cheap and inferior materials;

6. It is good to look at the appearance of inferior products, but due to poor workmanship, it is easy to crack, sand hole, slag, burr or bruising;

7, see "storage" auto parts if weather-shack, oxidation, BianSeJing or aging problems, may be in store environment is poor, and poor storage time is long, the material itself causes;

8. See "joint" if there is a clutch disc riveting, the brake rubber tube degumming, the electric parts joint soldering, the paper filter core joints removed and so on, it can not be used;

9. Look at the parts of normal parts marked with certain marks, such as gear marks, piston top marks and other assembly marks, to ensure the correct installation of the machine parts and no purchase;

10. The normal assembly parts must be complete in order to ensure smooth loading and normal operation. Some small parts on the assembly parts leak, usually "water cargo", which makes it difficult to load. Due to the shortage of individual parts, the whole assembly parts are scrapped.

11. The protective layer should be protected to keep the parts from being knocked off. For example, the liner, size bearing, piston, valve and so on are protected by paraffin wax, so as to avoid damage to the surface, these important accessories, if the surface is unprotected, are mostly "water";

12, see some documents important components, especially the assembly class, such as carburetor, distributor, generators, etc., when the factory generally with manual, certificate of approval, to guide users to install, use and maintenance, without these are fake and shoddy products;

13. When looking at the car parts, the main technical parameters should be identified and the special technology should meet the requirements. Some fake and inferior products look the same as real goods, but they are not suitable for them. They are either big or small, and they are not always satisfactory.

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