1, look at the glass label. In most cases, after the automobile glass is replaced, the label on the new glass will be very different from the original glass. Generally, the original glass label not only has the logo of the automobile brand, but also the logo of the glass brand. Due to some policies and regulations of automobile manufacturers, supporting manufacturers in the market prohibit the use of automobile brand trademarks. Therefore, most of the glasses that have been replaced only have the glass brand logo without the car brand logo;

2. Look at the production date, why should we look at the production date? Because under normal circumstances, the production date of the whole car glass is close to the production date of the whole car. If there is a big gap between the production date of a piece of glass and the production date of other glasses, it means that this glass has been replaced. If the production date of each glass is different, you should be careful. Rollover is possible. Automobile glass is similar to tires, and there is a way to see the production date through some figures above. But unlike tires, the calculation date unit of tires is weeks, while the calculation date unit of automobile glass is months;

3. Look at the manufacturer. By looking at the manufacturer code on the glass, you can see which manufacturer the glass comes from. Generally, automobile manufacturers buy glass in bulk, and don't use too many brands or the same brand from different places of origin. For example, the origin of a brand of vehicles is Shanghai, and its original glass should be produced by manufacturers in Shanghai and nearby, rather than choosing manufacturers in the north. Netizens can refer to whether the glass manufacturers of the whole car are all in one area to judge whether the glass has been replaced;

4. Look at the appearance, and judge whether the glass has been replaced by observing the appearance and surroundings of the glass. Generally, this method is not easy to distinguish, and it needs some common sense car owners to see the clue, and it is limited to the front and rear windshields.
