Commercial vehicles require frequent delivery and use, resulting in significant component wear and tear. Timely maintenance and replacement of old components will make our driving smoother and safer. For the sake of economy and convenience, many car enthusiasts are accustomed to purchasing car parts through the internet or auto repair shops. At this time, it is important to keep your eyes open and remember the several principles of choosing parts.

1、 Not greedy for cheap things

In automotive parts, counterfeit products are usually several times cheaper than genuine ones, but this comes at the cost of quality differences. So it's best to pay attention to the prices of commonly used car parts. If you find that the price of the product is too different from your impression, you should be vigilant. It is important to determine whether low-priced products are normal discounts or price reductions, or if they are counterfeit goods slacking off in troubled waters.

2、 Observe packaging

Generally speaking, the packaging box of authentic products has clear handwriting, accurate overprinting, vivid colors, and is labeled with product name, specifications, quantity, etc. Some important components are accompanied by user manuals. And many counterfeit products have rough packaging printing and no user manual. Authentic products are printed according to unified standard specifications, with clear and formal handwriting; Counterfeit and inferior products can always find flaws in their packaging.

For example, the original accessories of Changan Kaicheng are packaged in cardboard boxes, adhesive tape, plastic packaging with Changan logo, and have dedicated accessory labels. The surface of the accessory has a permanently engraved part name and part number, as well as a supply code. The supplier code rule is composed of a capital English letter and five Arabic numerals, such as "S04121". Alternatively, spray the part number, supplier code, and production batch number with white paint on the surface of the physical object.

3、 Select 'Original'

If the key components of the vehicle malfunction, you should go to the designated 4S store or service station of Changan Kaicheng to purchase authentic original parts; Fake and inferior parts that are not assembled by the original factory often cause damage to the vehicle body.

4、 Visual inspection of color

Some original accessories are specified with a certain color on the surface, and if other colors are encountered, they are mostly counterfeit and inferior products.

5、 Observe the paint

Some unscrupulous merchants sell discarded parts as qualified products after simple processing, disassembly and assembly, painting and packaging, illegally obtaining high profits. The authenticity of these parts can be determined by appearance painting or performance inspection.

Taking original sheet metal parts as an example, in order to prevent rusting of the accessories, they are all coated with electrophoretic primer without topcoat. Electrophoretic primer has strong adhesion on metal surfaces, with a smooth and bright surface. There are two types: gray and black. Changan Kaicheng chooses gray.

6、 Carefully examine the materials

Authentic products use high-quality materials according to design requirements, while counterfeit products often use cheap and inferior materials as substitutes. If rust spots are found on new parts, rubber parts crack and age, and there is detachment or debonding at the joints, such accessories are likely to have problems.

7、 Is there any protection

Most automotive components are coated with protective layers at the factory, such as piston pins and bearing shells protected with paraffin wax; Apply anti rust oil to the surface of the piston ring and cylinder liner, wrap the valve, piston, etc. with packaging paper, and then package them in plastic bags. If the sealing sleeve is damaged, packaging paper is lost, rust proof oil or paraffin wax is lost, even if it is not a counterfeit product, it will still damage the product.

Many car parts are related to driving safety, therefore, it is best for everyone to go to authorized dealers or service stations of Changan Kaicheng for maintenance and replacement of parts, which ensures better quality and safer driving.
