Picking good car parts is an important part of ensuring the performance, safety and longevity of your car. Here are some key tips to help you pick quality car parts.
1. Check the markings
-Completeness: The outer packaging of genuine products is of good quality, with clear writing on the box and bright overprint colours. The product name, specification, number, quantity, registered trademark, factory name, and other information should be marked on the package.
Quantity, registered trademark, factory name and address, contact number and other details should be marked.
Anti-fake signs: some important parts, such as generators, distributors, injection pumps, etc., can also be equipped with manuals, certificates of compliance and inspector seal, which helps to identify the authenticity.
2. Observe the combination of parts
-Flatness: parts may have burrs, indentations, breaks or cracks during handling and storage, affecting the use of the effect. Selection
Combined parts should be carefully checked to see if they are flat and flawless.
3. Evaluate the flexibility of rotating parts
Flexibility: For the oil pump and other rotating parts assembly, turn the pump shaft by hand should feel flexible and free of stagnation. Selection of rolling bearings, one hand to support the inner ring of the bearing, the other hand to spin the outer ring, the outer ring should be able to rotate quickly and freely and gradually stop. If the rotating parts do not rotate well, it may indicate internal corrosion or deformation.
4. Check the protective surface
Integrity: most of the parts in the factory are coated with protective layer. Selection should pay attention to check whether the protective layer is intact, such as piston pin, axial tile paraffin protection, piston ring, cylinder liner rust oil. If the sealing sleeve is found to be broken, wrapping paper is lost, anti-rust oil or paraffin wax loss, it should be returned.
5. Verify the geometry and shape
No deformation:Check whether the parts have deformation phenomenon. For example, the shaft parts along the glass plate rolling a circle, observe the parts and the glass plate affixed with no light leakage to determine whether the bending. Selection of oil seals, should check whether the end face is round, no deflection.
6. Confirm the integrity of the assembly components
-Completeness: the regular assembly components must be complete to ensure smooth assembly and normal operation. Selection should be carefully checked whether there are missing parts.
7. Check the surface corrosion of parts
-Finish: qualified spare parts surface should have a certain degree of precision and bright finish. Selection should pay attention to check whether the parts surface rust spots, mould spots or rubber parts cracking, loss of elasticity and other phenomena.
8. Observe whether the rubber parts are loose
-Tightness: by two or more parts combined into the accessories, parts are not allowed to have loose phenomenon. Selection if found loose, should be replaced.
9. Refer to the brand and reputation
Brand reputation: Choose well-known brands and auto parts brands with good reputation, which usually have stricter quality control and better after-sales service.
User evaluation:You can check the evaluation and feedback of other car owners to understand the actual use of accessories and problems.
10. Consult the professionals
Professional advice:If you are not sure how to buy, you can consult auto repair technicians or professional salespersons, who can usually provide more professional advice and help.
To sum up, choosing a good auto part requires comprehensive consideration of several factors, including logo marking, bonding area, flexibility of rotating parts, intactness of protective surfaces, geometric dimensions and shapes, integrity of assembly parts, surface corrosion of parts, tightness of glued parts, as well as brand name and reputation, and so on. Through careful inspection and comparison, you can choose the quality auto parts for your vehicle.
