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 replacement, the sealing of the car may slightly decrease, but due to the use of adhesive during the process, the issue is not significant. Impact of Improper Installation: Generally speaking, if the windshield is replaced correctly, there are no adverse effects. However, if installed improperly, the sealant on both sides of the windshield may not fit tightly against the glass, which can affect the car. For example, during high-speed driving, wind may enter through gaps between the windshield and the car body, leading to increased interior noise. Additionally, when driving on bumpy roads, you may hear a rattling or impact sound from the front of the car. Repairable Situations: If the car windshield is cracked, it doesn't always need to be replaced—some cracks can be repaired. However, repairs are only possible when the crack is on the outermost layer of the windshield. Generally, repairable crack types include star-shaped cracks and linear cracks.
Replacing windshields is actually quite common, and it's a frequent topic among my friends. The key lies in the installation process - if the workers are careless or the adhesive isn't applied evenly, sealing issues may arise, such as rainwater seeping in through the edges or a sudden increase in wind noise at high speeds. Professional shops use high-quality polyurethane adhesive and skilled techniques to ensure a tight fit, comparable to the original factory sealing level. After replacement, it's best to avoid washing the car for 24 hours to allow the adhesive to fully cure, followed by a simple water spray test to check for leaks. Poor sealing not only makes the car interior uncomfortable due to dust and moisture infiltration but may also lead to long-term issues like wire corrosion or reduced heating system efficiency. Choosing a reputable repair shop with a warranty can save a lot of hassle later on. These small details are truly worth spending money on to get right.
