Are the Drain Holes of a New Car Opened by the 4S Store?

[EthanRose]

The drain holes of a new car are already in an open state, so there is no need for the 4S store to open them. Concept: Vehicle drain holes are outlets designed to drain accumulated water from the vehicle during rainy weather. Generally, the drain holes are located in the following areas: the front windshield of the engine compartment, the four corners inside the sunroof, the lower part of the front and rear doors, inside the fuel tank cap, at the bottom of the spare tire in the trunk, and the gaps between the front and rear headlights and the body fenders. Precautions: There is usually a drain hole below the fuel tank cap. If it becomes blocked, water may accumulate in the fuel tank during car washes or rainy weather, potentially causing damage to the fuel tank. The spare tire in the trunk is generally located in a lower part of the body. When driving through water, if the water level rises above the headlights, water may seep into the interior of the vehicle. The drain holes in this area are used less frequently.
