Automobile drain holes are categorized into several types. One type is the door drain hole, designed at the bottom of the door to expel water that enters through the window gaps. The second type is the sunroof drain hole, which removes water from the sunroof gaps to prevent rainwater from corroding the rubber seals. More details about automobile drain holes are as follows: 1. Detail One: All vehicles are equipped with drain holes to discharge accumulated rainwater from the vehicle to the outside. The design principle and structure are relatively simple, and virtually all cars come with drain outlets. However, these drain holes are prone to clogging, so drivers need to regularly check their condition to ensure they function properly. 2. Detail Two: The drain holes are generally located near the car doors. If they cannot be found, the vehicle's user manual can be used as a reference to assist in locating them, helping to keep the car body dry and prevent corrosion.
