How to choose auto parts

Owners, we must pay attention to the following aspects when repairing auto parts. Don't let “Silver” be easily taken away.

Do not ignore packaging information

When selecting automotive parts, it is often easy to identify flaws on the packaging and should be carefully identified. In general, the authentic outer box is clearly written, overprinted, and vivid in color. It is marked with the product name, model number, quantity, registered trademark, factory name, site, and telephone number, etc. Parts such as generators, distributors, etc., are also equipped with instructions for use to guide users in proper use and maintenance. Some auto parts will be marked with "Indonesia", "France", etc., but they cannot provide the relevant import customs clearance procedures. The true and fake products are difficult to judge, and many of them may be counterfeit products.

No wear on the surface

The surface of the purchased new parts shall be free from wear. If any surface is found to be worn, or if the painted part reveals the presence of old paint after uncovering the surface paint, it shall be a disguised waste part. At this time, it must be returned.

Rotate parts to be flexible

The steering knuckle is one of the main parts on the steering bridge of a car, which can make the car run steadily and transmit the driving direction with sensitivity. When you buy a rotating part, turning it will feel no sticking and turning. If the rotating parts do not rotate smoothly, it indicates that the parts are rusted or deformed and cannot be purchased.

The binding site must be leveled

During the handling and storage of spare parts, due to vibrations and bumps, deformation often occurs at the joints. In the inspection of shaft parts, the shaft parts should be placed on a glass plate or other object with a flat surface to roll. See if the light leaks at the junction between the part and the plane to determine if the shaft part is straight or not.

No loose parts glued

A fitting consisting of two or more parts is assembled by pressing, gluing, or welding. No loosening is allowed between them. For example, the plunger of the oil pump and the adjusting arm are assembled by pressing; The clutch driven wheel and the steel plate are riveted together. The friction plate and the steel plate are riveted or glued together. The filter frame of the paper filter and the filter paper are glued together; the thread of the electrical equipment is welded. If it is found to be loose during purchase, it should be exchanged.

Parts surface without rust

Qualified parts surface, both a certain degree of precision and bright finish, the more important parts, the higher the precision, the more stringent rust-proof and anti-corrosion packaging. Should pay attention to inspection when purchasing, if you find parts of rusty spots, mold spots or rubber pieces cracking, loss of elasticity, or the surface of the journal has a clear turning pattern, should be exchanged.

Assembly components without missing parts

The regular assembly components should be complete and intact. If some small components on some assembly components are missing or missing, the components will not work properly or even be scrapped, which will cause potential safety hazards.
