【Car owner’s home car knowledge】With the advent of summer, heavy rainfall will once again "visit" most areas of China. After being used in the dry season, a large amount of dirt accumulates in the dead corners of the car. At this time, the drainage holes are blocked, and the car will face the embarrassing situation of "heavy rain outside the car and moderate rain inside the car." If sewers are the conscience of the city, then for cars, in order to live up to your "conscience", you should check the drainage holes before the rainy season and prepare for a rainy day.
Although the problem of clogged drain holes is not common, it will be very troublesome once it occurs. Not only will it be full of odor, it will affect the future use of the vehicle, but it will also leave light or heavy water stains on the interior panels. Although a 4S store only has dozens of cases of blocked drain holes a year, in order to eliminate the possibility of blocked drain holes, this article will introduce the location of the drain holes and the hazards of blockage, and use troubleshooting methods to determine the blockage and unblock methods, hoping to attract the attention of car owners.

●Drainage hole location
Drain holes on the car body are generally distributed in the following places: sunroof, inside the engine compartment, under the door panel, under the spare tire in the trunk, and inside the fuel tank cover. The most likely places to get clogged are in the sunroof and the engine compartment, because these two places are most easily ignored, and debris often accumulates here, causing the blockage to become more and more serious.
●Hazards of clogged drainage holes
Nowadays, car manufacturers are making more and more improvements in details. In order to prevent the drainage holes from clogging, the car manufacturers will use thicker rubber pipes and some even have direct open designs to allow water to drain along the rust-proofed car body. The "cheating" design of the cross-shaped drainage holes on the old Magotan has been greatly improved. But even this only reduces the chance of blockage of the drainage holes. The causes of blockage are different for drainage holes in different locations.
Fuel tank cap drain hole
We often ignore the situation inside the fuel tank cap after washing the car. Some vehicles have a drain hole because the fuel tank opening is upward and water easily accumulates in the lower part. This drain hole does not allow fallen leaves and other debris to enter. If it is clogged, it is basically caused by dust accumulation. More accumulated water will freeze the fuel tank cap in winter and breed bacteria in summer. In order to avoid this problem, some vehicles modify the interior shape to avoid the problem of water accumulation.
Drainage hole under door panel
Nowadays, most of the drainage holes under the door panels do not have hoses to guide them. Rainwater that leaks into the door will flow to the lower drainage holes along the door and be discharged. Because the drainage holes are in a low position, vehicles that drive on muddy roads for a long time will easily seal the drainage holes with mud. Car owners must pay attention to check. Once water accumulates in the door, the thin layer of waterproof membrane on the inside of the door panel cannot stop the erosion of a large amount of rain. A large amount of water will cause damage to the window lift, audio and other equipment.
trunk drain hole
Since the spare tire in the trunk is at a lower position in the car body, if the water wading position of the vehicle is too high or water seeps into the gap between the car lights, water will flow to this position along the interior of the car body. Therefore, drainage holes are reserved in the car. However, due to the inefficiency of using the drainage holes and the high probability of rainwater flowing back into the car, most manufacturers use soft plastic to block them and just open them when draining water.
