Do New Cars Need Their Drain Holes Opened?

[VonAbel]

Yes, they need to be opened. After purchasing a new car, it is essential to promptly check the drain holes on the doors to ensure they are open. If the drain holes remain closed, water can accumulate inside the doors during rain or car washes, leading to rust over time. Below is an introduction to car drain holes: 1. Depending on their location, car drain holes can be categorized into door drain holes, sunroof drain holes, air conditioning drain holes, fuel filler drain holes, and drain holes beneath the front windshield. 2. During regular use, it is important to frequently clear away visible leaves and debris near the drain holes inside the car. If a drain hole becomes blocked, water can accumulate inside the door, which over time can cause the door's sheet metal to rust and deteriorate.
