How to Identify the Production Year of Car Glass?
2 Answers
Methods to identify the production year of car glass: 1. The glass year is composed of black dots and numbers. If small black dots precede the number, it indicates production in the first half of the year, with the month calculated by subtracting the number of dots from 7. If the number precedes the small black dots, it indicates production in the second half of the year, with the month calculated by subtracting the number of dots from 13. 2. The glass year may also consist of black dots, a number, and asterisk-shaped black dots. The number represents the last digit of the year, the count of small black dots indicates the quarter, and the number of asterisks following represents the specific month within that quarter. The production date of the glass should predate the vehicle's production date. Knowing how to read the glass production date helps determine if the glass has been replaced. If the glass production date is later than the vehicle's production date, it means the glass was replaced afterward. The vehicle's production date is usually found on the vehicle's nameplate located on the B-pillar.
I recently researched how to identify the production year of car glass, and actually, there's a string of codes in the corner of each piece of glass. The key is to look at the combination of numbers and dots: the number represents the last digit of the year, for example, 9 could mean 2019 or 2009. The position of the dots determines the month—if the dots are on the left side of the number, subtract the number of dots from 7, so two dots would mean May; if the dots are on the right side, subtract from 13, so three dots would mean October. Last time I helped my dad check his car, I noticed his windshield had an 8 followed by two small dots, which calculated to August 2028 production. Remember to compare it with the vehicle's manufacturing date to avoid mixing up the decades. Additionally, some glass may also have a combination of black dots indicating the production week, but for us car owners, understanding the year and month is sufficient.
