In the purchase of auto parts, we often worry about accidentally buying fake and inferior parts and inappropriate parts. So, how can you buy the right accessories?
1. See if the model is suitable
Most auto parts have specified models and technical parameters.
2. Check whether the trademark logo is complete
The quality of the outer packaging of the authentic product is good, the writing on the box is clear, and the overprint color is bright. Some important components, such as generators, distributors, fuel injection pumps, etc., are also equipped with instruction manuals, certificates of conformity and inspector seals to guide users in correct use and maintenance. When purchasing, you should recognize it carefully to prevent you from buying fake and shoddy products.
3. Check for deformation
Some parts are easily deformed due to improper manufacturing, transportation and storage.
4. Check whether the joint is smooth
During the handling and storage of spare parts, due to vibration and bumping, burrs, indentations, breakage or cracks are often generated in the joint parts, which affects the use of the parts. Pay attention to check when purchasing.
5. See if there is rust on the surface of the parts
The surface of qualified spare parts has both a certain precision and a bright finish. The more important the spare parts are, the higher the precision is, and the stricter the packaging is to prevent rust and corrosion. When purchasing, pay attention to inspection. If the parts are found to have rust spots, mildew spots or cracked rubber parts, loss of elasticity, or obvious turning tool lines on the surface of the journal, they should be replaced.
6. Check whether the protective surface is in good condition
Most parts are factory coated. Such as piston pin, bearing bush with paraffin protection. The surface of piston ring and cylinder liner is coated with anti-rust oil and wrapped with wrapping paper. Valves, pistons, etc. are dipped in anti-rust oil and packaged in plastic bags. If the sealing sleeve is damaged, the wrapping paper is lost, and the anti-rust oil or paraffin is lost when purchasing, it should be returned.
