Why Leaks: Long Term Without Maintenance is the Key
Sunroof leaking your car will be like this? "Why is my skylight leaking?" Some car owners have found that the sunroof of the car is closed even though it is used for a period of time. However, it is still wet on rainy days. I wonder why.
This problem, the experts said, this is due to owners in the daily car will ignore the maintenance of the sunroof, and the sunroof of the sunroof will gradually wear out in use, the aging of the seal ring will not be timely maintenance and replacement if it is aging. Affects the sealing performance of the sunroof, leading to leaks in the sunroof. Nowadays, most cars are equipped with skylights to cater to the preferences of Chinese car owners. Some 4S shops even install sunroofs on their vehicles in stores. The workmanship and quality of these cars will also be uneven.
Some vehicle sunroofs will shift after the sealant is “lifted†after maintenance. This happens only when the sunroof goes down from top to bottom, or when it goes from bottom to top, it is “lifted up†to indicate the strip and The friction between the roofs is too great. This situation usually occurs shortly after the cleaning of the strip, which is because the dust on the strip has been wiped off and the friction coefficient of the strip has increased. Talc powder can be regularly lubricated to reduce excess friction on the basis of tightness.
Coupled with the low occupancy rate of sunroofs used by some owners, even many car owners are concerned about sunroofs, and they are prone to ageing when they are not maintained for a long time. To know that any one thing is prone to various problems if it is not used for a long time. So how do we do it?
DIY maintenance skylight is actually very simple
Many owners also know the importance of sunroofs, and they will think of necessary maintenance for sunroofs. Some car owners who like DIY would like to complete their maintenance work. How to maintain sunroofs? The technicians answered this question for us. The basic content of self-operated maintenance of the sunroof is very simple: you can open the sunroof completely, wipe the dust on the slide with a clean soft cloth, and then use a lubricant that does not absorb dust. Lubricate the slide section of the sunroof and the transmission pipe.
In addition, daily special attention must be paid to the dust protection of the sunroof seals. In spring and autumn, you can use a wet sponge to clean the seal once every quarter. Before the vehicle is parked for a long time, it is necessary to thoroughly clean the skylight with talcum powder in order to avoid the natural aging caused by the chemical changes in the air in the air.
In the usual car wash, be sure to check the skylight's strips and grooves for dust, leaves, or twigs. When using the high-pressure water gun to wash the car, do not directly spray the water directly at the sealing ring around the sunroof. Otherwise, the sealing ring may be deformed under the pressure of the high-pressure water column. It will be easy to enter the water within a long time.
Leak repair is a priority
From the normal design, the sunroof can guarantee the corresponding seal. And many original sunroofs rarely leak. There are several reasons for leakage. One is a problem with the drainage system. There is a pit at the sunroof. If the drainage is not good, it will flow into the room. The cause of water leakage is mainly the two drain pipes in the A-pillar. For example, when the rubber of the sealing joint is aged or damaged, it will cause water leakage.
It is advisable to go to the repair shop to let the service technician take the water and test the skylight, find the leak point and then repair it. Another reason is that the vehicle is leaking due to a collision accident, which is likely to make the vehicle's body size not correct.
The sunroof leak after the collision requires the technicians of the 4S shop to use the most primitive sheet metal technology to find the deformation point by point, and carry out the sheet metal work to restore the deformation of the roof. This is a work that takes a long time, and the owner does not choose to change the roof, only to repair the sheet metal.
