Auto parts purchase tips

1. Check whether the trademark logo is complete. The outer packaging of authentic products is of good quality, the writing on the packaging box is clear, and the overprinting color is bright. You should carefully identify it when purchasing to prevent buying counterfeit and shoddy products.

2. Check whether the geometric dimensions are deformed. Some parts are prone to deformation due to improper manufacturing, transportation, and storage. The outer edge of the skeleton-free oil seal should be straight, and it should be deformed by holding it with your hand, and it should be able to return to its original state after letting go. When purchasing various types of gaskets, you should also pay attention to checking the geometric dimensions and shapes.

3. Check whether the joint is flat. During the transportation and storage of spare parts, due to vibration and collision, burrs, indentations, breakage or cracks often occur at the joints, affecting the use of parts.

4. Check whether the surface of the parts is rusted. The more important the spare parts are, the higher the precision is, and the stricter the packaging is for rust and corrosion prevention. The surface of qualified spare parts has both a certain precision and a bright finish.

5. Check whether the protective surface is intact. Most parts are coated with a protective layer when they leave the factory. For example, piston pins and bearings are protected with paraffin; piston rings and cylinder sleeves are coated with anti-rust oil and wrapped with packaging paper; valves, pistons, etc. are soaked in anti-rust oil and packaged in plastic bags.

6. Check whether the glued parts are loose. The parts are pressed together, the friction plate and the steel plate are riveted or glued; the paper filter element frame and the filter paper are glued; the wire ends of electrical equipment are welded. Select

7. Check whether the rotating parts are flexible. When purchasing rolling bearings, support the inner ring of the bearing with one hand and rotate the outer ring with the other hand. The outer ring should be able to rotate quickly and freely, and then gradually stop. If the rotating parts do not rotate properly, it means that the inside is rusted or deformed, so do not buy it.

8. Check whether the assembly parts are missing. Regular assembly parts must be complete and intact.

Replacement cycle of important car parts:

1. Air filter:

The replacement cycle of the air filter is about 10,000 kilometers or 1 year. Blow it with an air gun for each minor maintenance. If the filter is full of dust, it needs to be replaced.

2. Gasoline filter:

It should be replaced every 10,000-20,000 kilometers; and the oil pump can be replaced every 60,000 kilometers. If it is not replaced, the oil cannot be filtered, which will cause the internal parts of the engine to wear faster due to impurities in the oil.

3. Air conditioning filter:

It should be replaced every 15,000 kilometers or once a year, but it is recommended to replace it once or twice before turning on in winter or summer, depending on the air quality.

Auto parts (autoparts) are the various units that make up the whole car and a product that serves the car. There are many kinds of auto parts, and the categories of auto parts are:

1. Starting system

Engine assembly, filter, cylinder and parts, oil seal, oil pump nozzle, fuel saver, valve tappet, oil pipe, connecting rod assembly, crankshaft camshaft, bearing and connecting rod bearing, valve and parts, fuel tank, piston, flywheel ring gear, tensioner, belt, supercharger, carburetor, three-way catalytic converter, fuel injection device, starter and accessories, other starting system and other auto starting system accessories.

2. Travel system

Front axle, rear axle, shock absorption system, suspension system, bridge housing, half shaft, balance block, buffer, rim, wheel hub, frame assembly, car tire, agricultural vehicle tire, engineering machinery tire and other travel system and other auto parts.

3. Car body accessories

Car shell, car door, car glass, car mirror, license plate frame, seat and accessories, car bearing, armrest, handle, handle, center grille, fender, cab and accessories, airbag, car seat belt, glass lifter;

Car antenna, wiper, car muffler, car horn, car seal bumper, luggage box, luggage rack, extrusion, stamping, exhaust pipe, other car body accessories and other auto parts.

4. Steering system

How to choose auto parts:

1. Look at the packaging:

Original parts packaging is generally standardized, with unified standard specifications and clear and regular printing, while counterfeit product packaging is relatively crude and printing is often easy to find flaws in the packaging;

2. Look at the color:

Some original parts have a certain color specified on the surface. If other colors are encountered, they are counterfeit and inferior parts;

3. Look at the appearance:

Original parts have clear and regular printing or casting and markings on the surface, while counterfeit products have a rough appearance;

4. Look at the paint:

Illegal merchants process waste parts through simple processing, such as disassembly, assembly, assembly, combination, painting, etc., and then sell them as qualified products to illegally obtain high profits;

5. Look at the texture:

The materials of original parts are qualified materials according to design requirements, while counterfeit products are mostly made of cheap and inferior materials;

6. Look at the craftsmanship ：

Poor products may look good sometimes, but due to poor manufacturing process, they are prone to cracks, sand holes, slag inclusions, burrs or bumps;

7. Check "storage":

If auto parts have problems such as cracking, oxidation, discoloration or aging, it may be caused by poor storage environment, long storage time, poor material itself, etc.;

8. Check "joining":

If the clutch plate rivet is loose, the brake hose is debonded, the electrical parts joint is desoldered, and the paper filter element joint is detached, it cannot be used;

9. Check the logo:

Some regular parts are marked with certain marks, such as the gear mark, the piston top mark and other assembly marks to ensure the correct installation of the parts. Those without them cannot be purchased;

10. Check the missing:

Regular assembly parts must be complete and intact to ensure smooth installation and normal operation. Some small parts on some assembly parts are missing, which are generally "parallel imports", which cause difficulties in loading. Often, the entire assembly is scrapped due to the shortage of individual small accessories;

11. Check the protective layer:

In order to facilitate storage and prevent parts from being bumped, parts have a protective layer before leaving the factory. For example, bushings, large and small bearings, pistons, valves, etc. are generally protected with paraffin to prevent their surface damage. If these important accessories do not have a protective layer on the surface, they are mostly "parallel imports";

12. Check the certificates:

Some important parts, especially assemblies, such as carburetors, distributors, generators, etc., are generally accompanied by instructions and certificates when leaving the factory to guide users in installation, use and maintenance. If these are not available, they are mostly counterfeit and shoddy products;

13. Check the specifications:

When purchasing auto parts, it is necessary to find out the main technical parameters, and special technologies must meet the requirements of use. Some counterfeit and shoddy products look almost the same as the real ones, but they are not very suitable when installed, either too big or too small, and they are always not very satisfactory to use, and leave potential accidents.

14. The test report issued by a third party can not only prove the authenticity, but also show its quality.

The things made of auto parts are actually very messy. General auto parts are defined as selling parts of existing vehicles, including body panels (shells), engine parts or complete machines, transmissions, tires, etc. Anyway, as long as they are installed on the car, they are all sold. In addition to selling auto parts, current auto parts stores also sell lubricants (engine oil, gear oil, brake oil, steering oil, lithium grease, etc.), car coolants (water tank water, such as antifreeze), and car maintenance products. Remember to adopt it.
