Where is the car chassis waterproof plug located?

[LeBrooklyn]

Car chassis waterproof plugs are located inside the fenders on both left and right sides. Below is a detailed introduction about car chassis waterproofing: Introduction: Apart from normal drainage phenomena in internal operating systems such as the air conditioning system, muffler, and exhaust pipe, the car chassis also features specially designed drainage holes to discharge accumulated water from the vehicle body during rainy or snowy weather. These drainage holes include the engine compartment drainage hole, sunroof drainage hole, door drainage hole, and trunk drainage hole. Sunroof Drainage Hole: The sunroof drainage holes are generally located at the four corners of the sunroof on the car roof. After rainwater enters the drainage holes, it flows through the conduits inside the A-pillar/C-pillar and is eventually discharged from the drainage outlets near the front and rear fenders at the bottom of the car.
