How to Check the Production Date of Glass on Changan Vehicles?
1 Answers
The production date of automotive glass is primarily displayed in two ways. The first method uses a combination of black dots and numbers or numbers and black dots. The second method uses numbers, small black dots, and asterisk black dots. For the first method (black dots plus numbers or numbers plus black dots): If small black dots precede the number, it indicates production in the first half of the year, with the month calculated as 7 minus the number of small black dots. If the number precedes the small black dots, it indicates production in the second half of the year, with the month calculated as 13 minus the number of small black dots. For the second method (numbers plus small black dots and asterisk black dots): Typically, the number comes first, followed by several small black dots and then asterisk black dots. The interpretation is as follows: the number represents the last digit of the year, the small black dots indicate the quarter (e.g., two dots represent the second quarter), and the asterisk black dots represent the month within that quarter (e.g., four asterisks indicate the fourth month). When purchasing glass, automakers ensure that the windshield, rear window, side windows, and sunroof glass are from the same batch with identical production dates to guarantee glass quality. If a vehicle has glass with a different production date from the others, it suggests that the glass has been replaced, indicating the vehicle may have been involved in an accident.
