How to Check the Production Date of Imported Car Glass?
2 Answers
Methods to check the production date of imported car glass: 1. The most common method (80% usage): a. Date format: Numbers + dots, where the dots can be in front of or behind the numbers. b. How to read: If the dots are in front of the numbers, it indicates the first half of the year—subtract the number of dots from 7. If the dots are behind the numbers, it indicates the second half of the year—subtract the number of dots from 13. 2. Less common format: a. Date format: Numbers + small dots + large dots. b. How to read: The numbers represent the year, small dots represent the quarter (maximum 4 dots for 4 quarters), and large dots represent the month within the quarter (maximum 3 dots for 3 months). 3. The most complex format: a. Date format: First line—numbers + small dots; second line—large dots + small dots. b. How to read: The numbers represent the production year. The small dots on the first line represent the month (1-12 dots). The second line represents the days in the month—large dots stand for 10 days, and small dots stand for 1 day.
I've spent most of my life working in repair shops, and checking the production date of imported car windows is as routine as eating meals for me. You usually need to get close to the corner of the window and look carefully for a coding area there. The number represents the last digit of the year, for example, 9 would mean 2019. The dot may be in front or behind the number. When the dot is in front, the number of dots plus one equals the month. When the dot is behind the number, the number of dots plus seven equals the month. My regular customers often ask me about this trick, mainly to determine if the window is original or has been replaced, to avoid buying a car that's been in an accident. Sometimes the location of the imported car window is hidden, but using a small mirror can make it clear. Remembering this method is especially useful for used car inspections and can save you a lot of unnecessary expenses.
