How to Check the Date on Car Windows?
3 Answers
There is a code located at the bottom left or right corner of the car window glass. The production date of the glass can be identified by the numbers and small black dots in the last or second-to-last row. Relevant information about car windows is as follows: 1. Introduction: The car window (car-window) is an essential part of the vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. 2. Window Names: Depending on the installation position of the glass, car windows are categorized into: front and rear windshields, side windows, and door windows. The design, structure, and quality of the windows significantly impact the driver's visibility, passenger comfort, exterior aesthetics, and aerodynamic characteristics.
I've been driving an old car, and the window date can be found in the corner upon close inspection, usually a combination of a number and a small dot. For example, if you see '20.', it means the glass was produced in 2020. The dot before the number indicates the first half of the year, while the dot after means the second half. My car's windshield has this code in the lower right corner, which I note down for regular age checks. Aged glass is particularly dangerous on long trips, as it's prone to cracking or even shattering. I recommend taking a quick glance at it every six months when washing the car. If you find the date too old, like from 10 years ago, it's time to consider replacing it. Window quality is crucial for clear visibility and emergency protection, so don't overlook this small detail.
I'm very familiar with automotive parts. The window date is printed as a small code on the edge of the glass, and decoding it is simple: the numbers indicate the last two digits of the year, and the dot distinguishes the position of the month. For example, '19.' means the product was made in the first half of 2019. The location is usually near the black border or in the corner of the door glass. The production date helps determine if it matches the original factory specifications or if replacement is necessary. I recommend checking it against the vehicle's maintenance records because old glass loses strength quickly and is prone to cracking or shattering on bumpy roads, posing a safety risk. Once you understand the format, it's easy to read at a glance.
