Cleaning drainage holes (Opel Astra J)

During vehicle operation, with sharp changes in outside air temperature, moisture condenses in the internal cavities of the body and doors. In addition, when washing the car and in the rain, water can penetrate into these cavities. The water accumulated in the cavities causes corrosion of the body panels and doors.



To remove water, drainage holes are made in the lower edges of the side doors and in the thresholds. Over time, the drainage holes become clogged with road dirt, so periodically (preferably at every car wash) clean these holes with a thin wooden stick or screwdriver.



Three drainage holes are also made in the lower edge of the tailgate.

They should also be cleaned periodically, similar to the holes in the side doors.
