How to Check the Production Date of New Car Glass?
2 Answers
New car glass dates can be found by locating a code in the lower left or right corner of the window glass. The last or second-to-last row contains a number and several small black dots. These dots indicate the production month of the glass. If the dots are in front of the number, subtract the number of dots from 7; if the dots are behind the number, subtract the number of dots from 13. The result is the production month. Some glass may also have a few larger black dots after the production year and month, which indicate the specific week of the month. For example, 5 dots represent the first week; 4 dots represent the second week; 3 dots represent the third week, and so on.
Checking the production date of new car glass is actually quite simple. There are small codes in the corners of the glass, consisting of a number and a decimal point. The number usually represents the last two digits of the year, for example, 23 stands for 2023. The dot represents the month. If the dot is on the left side of the number, it indicates the first half of the year, and the month is calculated by subtracting the number of dots from 7. If the dot is on the right side, it indicates the second half of the year, and the month is calculated by subtracting the number of dots from 13. For example, if the windshield is marked with three dots and 23, with the dots on the left (indicating the first half of the year), the number of dots is 3, so 7-3=4, meaning April. The code is usually located at the bottom of the windshield or the edge of the window. When buying a new car, it's essential to check this because it helps you determine if the car is freshly manufactured. If all the glass dates are inconsistent or earlier than the vehicle's production date, the car might have been stored for too long, turning into overstock. I recommend using a flashlight at the dealership to carefully inspect the dates on several pieces of glass, ensuring they are close to each other and match the vehicle's production time. This can help avoid quality issues later on.
