Car window untight seal failure and solving methods

In the car window glass damage, want to change with the same original window glass, at the same time to check the glass guide groove and seal has no damage. Because of the window after repair is often difficult to return to its original shape, therefore, when in addition to ensure easy pulling or lifting window glass, but also pay attention to the window glass in the windows closed after around of tightness, you need Auto tools to detect.

When changing the car roof, the roof should be applied at the periphery lamination layer of conductive sealant, well then be welded seams in the water tank and fold over the painted plastic, which will not only contribute to the body of the seal, but also can prevent the body for flanging seam water, you need Launch X431 GDS or Launch X431 Diagun III tools to detect.

Produced early rust. When you want to assemble the door panel in the door window to paste an entire sealed off following the film, if not forming a seal barrier film, you can use plain paper instead of plastic, and then affix the seal spacer film compaction, and finally carried out interior panels production assembly.

When repairing a door seal flange, the flange should be noted that repair damaged seal, to accurately restore the original shape of the flange. After repairing the door to be tightness check, check method is: put a piece of cardboard in a sealed position, close the door, and then pull the paper, based on the size of the rally to determine whether a good seal. If the force required to pull the paper too much explanation sealed tight, it will affect the normal shut the door, and may also make the seal due to excessive deformation surface quickly lost in the sealing performance; if the force required to pull the paper too small, that seal bad, often can appear the phenomenon of the rain. In the replacement of the door must pay attention to apply in the inner and outer plate flanging occlusal hemming adhesive for car door, and some left in the stamping process of small hole with the base tape block.

Repairing the car line, should be all body hole, hole in the sealing ring is arranged in the wire harness, because they not only act as a seal ring, but also play a role in the protection harness. If the seal is damaged or harness can rotate or ran in the ring, you should replace the seals, and compare it with the body hole, hole assembly firm, stable good harness. you can use Autel MaxiDas DS708 or Autel MaxiSys Pro MS908P tools to detect.

When replacing the entire body, except for the above projects should be completed, but also on the lap portion of the weld joints are coated with a layer of sealant layer thickness should be about 1mm, and may not have a virtual sticky glue , bubbles and other defects; at the hem hem should be coated with special glue; in the entire floor surface should be coated elastomeric coating and anti-corrosion coating 3mm-4mm lower surface and the front cover; to paste the sound and heat insulation, vibration damping plate surface and the surface of the film in the floor, and then covered with insulation block, finally put on a carpet or a decorative floor. The corrosion rate of these measures can not only greatly enhance the vehicle sealing and slow down the body, but also can greatly improve the ride comfort.
