How to Check the Production Date of Toyota TSG Glass?
3 Answers
Toyota TSG glass production date identification techniques are as follows: 1. Determine the year: This format of date code has only one digit, which represents the last digit of the year. It can be determined based on the vehicle's manufacturing date. If the vehicle's production date is in 2007 or 2008, the glass year digit 8 should indicate 2008. The production dates of the glass and the vehicle won't differ by more than 10 years. 2. Determine the month: Dots before the digit indicate the first half of the year. Calculation formula: 7 - number of dots before digit = month. Dots after the digit indicate the second half of the year. Calculation formula: 13 - number of dots after digit = month.
When my car glass needs replacement, I learned that Toyota's glass production date can be found by locating a small serial code in the corner, usually starting with DOT followed by numbers and dots. Specifically, first find the printed markings on the edge of the windshield or other windows, and carefully observe the positions of the numbers and dots. The year is represented by the last two digits, for example, 23 means 2023. The month is determined by the position of the dots: if the dots are on the left side of the number, the number of dots indicates the month from 1 to 9; if the dots are on the right side, it represents October to December, calculated by adding 10 to the number of dots, for example, two dots mean November. Remember that the code may have multiple parts, so be patient and examine it carefully. The glass manufacturing date is very helpful for understanding the vehicle's history, such as checking whether the glass is original or has been replaced due to an accident when buying a used car, to avoid purchasing a problematic vehicle. For daily maintenance, it's also important to pay attention to the aging condition of the glass. Based on the production date, you can determine whether regular inspections for cracks or signs of aging are necessary to ensure driving safety.
I own a Toyota and once successfully identified its production date through markings in the corner of the windshield. The method involves locating a code resembling 'DOT' followed by numbers on the glass edge, where the digits represent the last two digits of the year (e.g., '22' for 2022). The dots indicate the month: dots to the left correspond to January through September (count the dots for the month number), while dots to the right signify October through December (subtract 9 from the dot count). Using a phone flashlight to illuminate the area makes the markings clearer. This trick helps assess a vehicle's usage timeline—for instance, I detected replaced glass when purchasing my car, saving on potential repair costs. Windshield age matters too, as newer glass ages slower. Regular checks can prevent wiper wear or sun damage from affecting visibility. Make it a habit to glance at these markings during car washes—it’s a small routine with big benefits.
