How does the water drain out of the car？
Car internal drainage is very important, the following is the introduction of effective drainage methods and drainage holes:
First, car drainage method:
1. Slight water: If the car is only slightly water, you can open the window in sunny weather, so that the water in the car naturally evaporates.
2. More water: If there is more water in the car, it is necessary to clean up the water in the car. The lower part of the vehicle chassis is provided with a sealant plug, which can be opened to discharge water.
3. Remove moisture: If there is still moisture in the car, you can open the air conditioning, adjust the circulation switch to the outer circulation, so that the water vapor in the car is discharged.
Second, car drainage hole introduction:
1. Air conditioning drainage hole: responsible for discharging the condensed water generated during the use of air conditioning, generally located at the lower part of the evaporation box.
2. Engine room drainage hole: located on both sides of the front windshield wiper, used to discharge sewage and fallen leaves.
3. Skylight drainage holes: The four corners of the skylight are provided with drainage holes, which need to be cleaned regularly to prevent blockage.
4. Tank cover drainage hole: the drainage hole provided at the lower part of the tank port is used to discharge water.
5. Door drainage hole: located at the lower part of the door panel, long-term driving on the muddy road should pay attention to cleaning.
6. Trunk drainage hole: located in the spare tire pit, can be opened manually in extreme cases.
7. Bottom large side drainage hole: some large SUVs are equipped with this drainage hole, which should be maintained to prevent rust.
In fact, there are many drainage holes hidden in various parts of the car, and the normal operation of the drainage holes affects the use of the car to a large extent. Most of the time it's not that we don't pay attention to it, but that we simply don't know its importance, or even where it is.
The drainage holes of the car are generally distributed in the fuel tank cover, engine compartment, under the door panel, skylight and other places, and the most easily blocked places are in the skylight and engine compartment.
1. Oil tank cover drainage hole
Open the cover of the fuel tank filler port, and you can see the drainage hole under the oil tank cover. The oil tank cap is not tightly sealed, and the inside is concave, so a drainage hole is designed. Because the vehicle is used outdoors, wind sand will pass through the gap of the oil tank cap and accumulate around the oil tank cap. If the drainage hole is blocked, it may be thought that the water in the tank is stagnant in the car wash or rainy weather, resulting in damage to the tank.
After washing the car, we are easy to ignore the situation in the tank cap, some car fuel tank opening is on the upper side, the lower part is very easy to collect water, then the design of the drainage hole, the drainage hole blockage is mostly due to the accumulation of dust, more water will freeze the tank cap in winter, and the summer will breed bacteria.
2. Skylight drainage holes
Generally speaking, if the skylight is not opened for a long time, the possibility of blockage of the four drainage holes at the skylight is small, and blocking one is not enough to make the water flood into the car. In most cases, the water is caused by water infiltration in the rubber gap, and the moisture of the interior decoration board is the manifestation of the blockage of the skylight drainage hole. The loss of the skylight drainage pipe will also cause the interior decoration board to be damp. Damp interior will not only bring unpleasant musty smell, but also will breed bacteria.
3.3. Lower drain hole of door panel
The door drain holes are located at the lower part of the door plate. There are generally 1-2 holes. Most of the lower drainage holes of the door panels do not have hoses for dredging, and the rainwater is discharged directly through the door panels treated with rust prevention. Nowadays, most of the door panel lower drainage hole and no hose to dredge, leakage into the door of the rainwater will flow down the door to the lower drainage hole discharge, due to the low location of the drainage hole, long-term driving in the muddy road vehicles, the drainage hole is easy to be blocked by silt, the owner must pay attention to check, once the water in the door, The thin waterproof film on the inside of the door panel is unable to prevent the erosion of a large amount of rain, and a large amount of water will cause damage to the window lift, audio and other equipment.
The various drainage holes on the car body, among which the most easily blocked place in the sunroof and engine compartment, because these two places are most easily ignored, and debris often accumulates here leading to more and more serious blockage, owners should regularly clean up the health of the car, maintain the various parts of the car to prevent the car drainage holes from being blocked.
