Are the Drainage Outlets of New Cars Opened?
2 Answers
New cars' drainage outlets are not opened and need to be opened manually. Here is the relevant information: 1. Precautions: When cleaning hidden hoses such as those for the sunroof, avoid using hard objects like iron wires to unclog them, as these objects may cause the hoses to break or detach. Compared to other components in the car, the drainage holes, which are simple in principle and seemingly insignificant, are often overlooked. However, these small drainage holes can frequently cause significant trouble during vehicle use. You can routinely inspect and address these minor issues yourself. 2. Drainage Outlets: Apart from the sunroof drainage holes connected to hoses, the drainage outlets in areas like doors and front/rear taillights generally drain directly through the drainage channels inside the doors.
When I first got my new car, I also wondered about the drainage holes. There are designed drainage outlets in places like the doors, sunroof, and fuel tank cap, and these are all kept clear when the car leaves the factory. However, minor accidents can occasionally happen during transportation, such as leftover dust-proof stickers or wax seal residues. Last week, while helping a friend inspect his car, I found the door drain hole blocked by a sealing strip—just poking it with a thin wire cleared it. Especially remember to check the sunroof drainage tubes; I've seen many new owners experience water dripping inside the car during heavy rains, all because leaves blocked the hidden hoses in the A-pillars. There are also two small holes at the seams of the trunk lid, often overlooked. Regularly using compressed air to blow out the drainage channels during car washes can save a lot of trouble.
