There are four drainage holes in the car. The first is the sunroof drainage hole, the second is the engine compartment drainage hole, the third is the drainage hole at the bottom of the door, and the fourth is the drainage hole at the bottom of the trunk. The following is a related introduction to Changan Oushang: 1. Introduction: Changan Oushang is a new passenger car brand under Changan Automobile (Group), forming the "one body, two wings" of Changan's independent passenger car brand development together with Changan Automobile. Changan Oushang fully shares Changan Automobile's global R&D, procurement, and manufacturing systems to create products that better meet the travel needs of young Chinese families. 2. Company Introduction: With the slogan "Walking with a Better Life," Changan Oushang is committed to becoming a user-led brand that is more concise, efficient, friendly, and approachable. It advocates growing together with users, co-creating value, and helping users pursue a better quality of life.

When driving the Changan Oushang, I noticed that the drain holes are mainly located along the bottom edges of the doors, where small holes allow rainwater to drain out. Additionally, if the model is equipped with a sunroof, there are drain holes around the sunroof frame to prevent water from accumulating inside the vehicle. I remember one time during heavy rain, the door didn't drain properly, and some water leaked into the car. Later, I learned to gently clear these holes using a thin wire or a straw to avoid water accumulation, which can lead to rust or damage to interior components. There's also a drain hole in the engine compartment below the windshield. If not cleaned regularly, it can become clogged over time, affecting the air conditioning system. Regularly checking these areas can save a lot on repair costs, especially when parked under trees, as leaves and dust can easily block the holes. It's recommended to inspect and clean them after each car wash.

I've worked on many Changan Oushan models in the garage, and the most common drainage holes are located under the doors and around the sunroof on the roof. When you open the door, you can see those small holes at the bottom, which are positioned quite low and prone to debris accumulation. I often encounter customer vehicles with battery compartment flooding or seat corrosion due to poor drainage. Therefore, I recommend avoiding parking under trees where leaves can fall. Cleaning these holes every few months with a soft brush or high-pressure air can prevent such issues. There are also drainage holes under the windshield, sometimes tucked away and requiring a closer look from underneath. Keeping these areas clear helps avoid minor problems like unpleasant air conditioning odors. Doing this maintenance yourself not only saves money but also extends your vehicle's lifespan.

From a safety perspective, blocked drainage holes on Changan Oushan vehicles can pose risks. For example, clogged holes at the bottom of doors may allow water to seep into the cabin, damaging wiring or electronic components. I often remind people to check these locations along the vehicle's underbody edges and sunroof frame to ensure proper water drainage and prevent body rust or structural corrosion. Prevention is simple: regularly cleaning these holes with a thin rod or compressed air can prevent leaks and mechanical issues, ensuring driving safety. Never wait until problems occur before taking action.
