How to buy automotive? First, look at the packaging. The original accessories packaging is generally more standardized, unified standard specifications, clear and formal writing, should be marked with product name, specifications and models, quantity, registered trademark, factory name, factory address, and telephone number, etc. Some manufacturers also mark on accessories. Second, look at the appearance. The printed or cast characters and marks on the surface of qualified accessories are clear and regular. The more important the accessories are, the higher the precision is, and the stricter the anti-rust and anti-corrosion packaging. If it is found that the parts have rust spots or cracked rubber parts, lose elasticity, or have obvious turning patterns on the surface of the journal, they should be returned. Then, look at the paint. The unscrupulous merchants simply processed the waste accessories, such as disassembling, assembling, putting together, painting, etc., and then posing as "qualified products" for sale. After removing the surface paint, the old paint can be found. Besides, look at the craft. Poor products are prone to cracks, sand holes, slag inclusions, and burrs due to poor manufacturing processes. If the cylinder gasket is squeezed and deformed, it will easily cause abrupt sealing and ablation during use, resulting in oil leakage, air leakage, and water leakage. Finally, look at the specifications. Most automotive have specified models and technical parameters. If you buy electrical equipment, you should check whether the voltage and power of the replaced parts are consistent.
