How to Check the Manufacturing Date of Car Glass?
2 Answers
Car glass production date can be checked by looking at the trademark in the corner of the glass, which consists of several dots and a number. The number represents the production year of the car glass. If the dots are on the left, it indicates the first half of the year, while dots on the right indicate the second half of the year. Additional details: 1. First, the number is the production year of the glass, representing the last digit of the year. This must be determined based on the vehicle's manufacturing date. If the vehicle was manufactured in 2007 or 2008, then the glass year number '8' would correspond to 2008. The difference between the glass and vehicle production dates should not exceed 10 years. 2. The small black dots indicate the production month of the glass. If you observe other car glasses carefully, you will notice that some glasses have the black dots before the number, while others have them after the number. If the black dots are before the number, subtract the number of dots from 7. If the black dots are after the number, subtract the number of dots from 13. The result will give you the production month of the glass.
Let me teach you a super practical way to check the date on car glass. Squat down and look at the corner of the windshield, where you'll usually find a code made up of a series of dots and small numbers. For example, if you see the number '23' followed by three small black dots, it means the glass was produced in April 2023. The number represents the year, and the position of the dots is crucial: dots before the number indicate the first half of the year, while dots after indicate the second half, with each dot counting as one week. Remember this rhyme: 'First 6, last 6'—if the dots are in front, subtract the number of dots from 6 to get the month; if they're behind, subtract from 13. That's how I figured out that one of my car's windows was made in July 2023 and the other in November 2023. Even the repair shop mechanics praised me for being professional.
