Does Replacing the Windshield Affect Sealing?
2 Answers
There is basically no significant impact. The front windshield of a car is generally adhered to the windshield frame with sealant, and with sufficient adhesive, there is little difference from the original. After replacing the windshield, the sealing may slightly decrease. However, since adhesive is used in the process, the issue is not significant. Be sure to drive smoothly for the first few days after replacement to avoid vibrations. Additional tips: To prevent air or water leaks, avoid washing the car for three days, and remove the tape securing the windshield position after three days. Try to avoid driving on excessively bumpy roads to prevent windshield displacement. Avoid sudden braking and rapid acceleration, and maintain smooth driving.
As someone who frequently tinkers with cars, I feel that replacing the windshield can definitely affect the seal. Think about it—the windshield is glued to the car body with specialized adhesive. If the installation isn’t done professionally, like if the adhesive isn’t applied evenly or doesn’t cure properly, leaks and drafts will happen immediately. I once saw a friend replace their windshield at a cheap shop, and they used low-quality adhesive. Within two months, the car flooded during rain, soaking the seats and causing rust. If done professionally, they’d use high-quality polyurethane adhesive, ensure tight sealant application, thoroughly clean the frame, press it firmly with suction cups, and test for leaks before finishing. Don’t just save money—choosing a reliable repair shop is key. A failed seal isn’t just embarrassing; it also increases wind noise and rattles, and damages the car’s structural integrity over time.
