How to Check the Production Date on Car Glass?
2 Answers
To check the production date on car glass, follow these steps: 1. Look for the code at the bottom left or right corner of the window glass; 2. The numbers represent the year, and the dots represent the month. Dots before the number indicate the first half of the year, and the month can be calculated by subtracting the number of dots from 7. Dots after the number indicate the second half of the year, and the month can be calculated by subtracting the number of dots from 13. Types and functions of car glass: 1. Laminated glass: Transparent adhesive plastic film is applied between two or three layers of glass, enhancing the glass's resistance to breakage; 2. Tempered glass: Ordinary glass is quenched to form internal stresses. When impacted and broken, the glass splits into small pieces with blunt edges, reducing the risk of injury to passengers.
As an experienced car enthusiast who frequently tinkers with my vehicle, I've found that identifying the production date of car glass is actually quite simple. Typically in the corners of the windshield, side windows, or rear windshield, you'll notice a series of small dots or a combination of numbers and dots, which indicate the year and month. For example, the number 13 with dots represents 2013, and more dots signify a later month—eight dots, for instance, stand for August. This not only helps you gauge how old the glass is but also determines whether it needs replacement to avoid unexpected shattering risks. I once nearly overlooked this myself, only to later discover the glass was too aged; replacing it significantly improved safety. During regular car washes, take a moment to check these small markings—it’s an easy way to prevent issues. Just remember to inspect them in good lighting for clarity.
