How to Identify Genuine OEM Auto Parts?
3 Answers
To determine whether vehicle parts are genuine OEM (Original Equipment Manufacturer) components, you can check the part numbers on the components and then input these numbers into the 4S dealership's system for verification. Below are some relevant national policies regarding automobiles: 1. Regarding vehicle scrappage: Non-commercial private vehicles have no mandatory usage period but are recommended for retirement after traveling 600,000 kilometers. Vehicles failing annual inspections will be mandatorily scrapped by the state. 2. Regarding annual inspections: Vehicles aged between 6 and 15 years require annual inspections once per year. For vehicles over 15 years old, biannual inspections are required.
As an ordinary car owner who frequently replaces parts, I can tell if they're genuine by checking a few key details. First, I examine the packaging labels for the brand's official logo - for example, Toyota parts must have the exclusive TOYOTA emblem, along with barcodes and batch numbers on the packaging that can be scanned via smartphone to verify authenticity on the official website. Secondly, during installation, I compare the new part with the old one - genuine parts perfectly match in color, material, and weight, while aftermarket ones feel rough and noticeably lighter. Once when I replaced brake discs, the genuine ones performed smoothly and lasted long, whereas the aftermarket versions started making strange noises within just three months - experience taught me never to prioritize cheap prices. Finally, I check warranty information - genuine parts usually come with warranty cards or have traceable records at authorized 4S shops, so for online purchases I only choose official flagship stores to avoid counterfeits. Once you develop these habits, distinguishing real from fake becomes effortless - ensuring both safety and peace of mind.
I often help friends repair cars, and the simplest way to identify genuine parts is to test the installation fit. Use a multimeter to measure voltage or current—genuine parts match the factory parameters, while aftermarket ones may differ by a few tenths of a volt. Feel is also crucial. For example, engine components from the original manufacturer fit snugly and tighten securely, whereas aftermarket parts often feel loose and don’t seat properly. I frequently shop at auto parts markets and always check the anti-counterfeit laser codes—genuine ones feel smooth and have a 3D effect, while fakes are blurry and prone to fading. Performance testing is another method. After replacing an air filter, drive for a few days: genuine parts ensure smooth airflow and normal fuel consumption, while fake ones cause sluggish acceleration and carbon buildup. In summary, the right tools and experience are absolutely essential.
