How to buy cost-effective Petrol Car parts

What is a good way to buy Petrol Car parts, and how to buy the most suitable and cost-effective Petrol Car parts.

1. The packaging of original packaging accessories is generally relatively standardized, with unified standards and specifications, and clear and formal printing. However, the packaging printing of counterfeit products is relatively poor, and it is often easy to find defects in the packaging;
2. Look at the colors specified on the surface of some original parts. If there are other colors, they are fake parts;
3. The appearance is printed or cast, and the markings are clear and formal, while the appearance of counterfeit products is rough;
4. Look at the illegal dealers in paint who go through simple processing, such as disassembly, assembly, painting, etc., and then sell them as qualified products, illegally obtaining high profits;
5. According to the design requirements, the original design requires the use of qualified materials, and counterfeit products mostly use cheap and inferior materials;
6. Look at the appearance of products with poor workmanship. Sometimes, although they look good, due to poor production technology, they are prone to cracks, sand holes, slag inclusions, burrs or bruises;
7. If there are problems such as drying, oxidation, discoloration or aging when storing Geely Car parts, it may be due to poor storage environment, long storage time, poor materials themselves, etc.;
8. It cannot be used if the clutch rivets are loose, the brake hose is deglued, the electrical component joints are desoldered, or the paper filter seams fall off, etc.;
9. Mark some marks on the official parts of the logo part, such as time gear mark, piston top mark and other assembly marks, to ensure the correct installation of the parts without purchasing;
10. Check that the missing formal components must be intact to ensure smooth loading and normal operation. Some small parts on some components leak, usually parallel imports, making loading difficult. Due to shortages of individual small parts, entire components are often scrapped;
11. Look at the protective layer. In order to facilitate storage and prevent parts from colliding, parts have a protective layer before leaving the factory. For example, bushings, large and small bearings, pistons, valves, etc. are generally protected by paraffin to avoid damaging their surfaces. If there is no protective layer on the surface, most of these important accessories are parallel imports;
12. Check the certificate for some important components, especially the assembly, such as carburetor, distributor, generator, etc. When leaving the factory, there are usually instructions and certificates to guide users in installation, use and maintenance. If not, most of them are fake products;
13. When purchasing Geely Car parts, the main technical parameters should be ascertained, and special technologies should meet the usage requirements. Some fake and shoddy products are similar in appearance to genuine products, but are not suitable for installation, large or small, and are always unsatisfactory when used, leaving potential accidents.
14. The test report issued by a third party can not only prove the authenticity but also show its quality.
