In general, it is recommended to replace car seals within three to four years. This is because the sealing strip is a rubber product that will naturally age over time, thereby affecting its sealing performance.
However, the actual replacement frequency still needs to consider the specific situation and maintenance status of the vehicle. If the vehicle is frequently exposed to sunlight or parked in a cool place such as a garage, the aging rate of the sealing strip may slow down, so the replacement cycle can be correspondingly extended.
If the sealing strip is severely damaged, such as cracks or fractures, it should be replaced immediately instead of waiting until the preset time interval.
When deciding whether to replace, the sealing strip should also be checked for obvious signs of wear or damage, as well as whether special adhesive has been used for repair.
In summary, although it is generally recommended to replace the sealing strip every three to four years, the actual situation should be determined based on the actual use and maintenance of the vehicle. If there are any questions or problems with the sealing strip, it should be checked and replaced in a timely manner.
