Where is the drainage hole of the Changan CS35 trunk located?

[DeLydia]

The drainage hole in the trunk is located beneath the spare tire and is sealed with a rubber plug. The drainage hole prevents rainwater from entering the vehicle body during rainy conditions and drains liquids from the car to the outside, fulfilling its intended function. Location of drainage holes: The drainage holes of a car are generally distributed in areas such as the fuel tank cap, engine compartment, below the door panels, sunroof, etc. The most prone areas to clogging are the sunroof and engine compartment. Classification of drainage holes: The drainage holes in a car are mainly divided into the following categories: engine drainage hole; door drainage hole; sunroof drainage hole; fuel tank cap drainage hole; air conditioning drainage; exhaust pipe drainage hole.

I've been driving the Changan CS35 for several years, and it took me some effort to locate the trunk drain holes before. The design of the drain holes on this car is quite hidden, not something you can spot at first glance. The specific locations are at the four corners of the spare tire well, and you need to lift the trunk mat to find them. Last week when I was washing the car, I just cleaned them: first, remove all the clutter from the trunk, peel back the felt mat, then take out the spare tire (my model doesn't have a full-size spare, just a small storage compartment), and at the four corners of the spare tire well, you can see coin-sized round holes. These holes lead directly to the underside of the car, and they're crucial for draining accumulated water on rainy days. When parking under trees, be especially careful as fallen leaves can easily block the holes. It's recommended to check them every quarter. When cleaning, use a vacuum to remove debris and a soft brush to clean around the holes—never poke them with hard objects. Once, I forgot to clean them, which led to water accumulation inside the car, and it took several days of airing out to get rid of the smell.

Speaking of the drainage holes in the trunk of the Changan CS35, we need to start with the underbody design. I've carefully studied my car, and the drainage holes are located at the four corners of the spare tire compartment, slightly smaller than a standard bottle cap. During the last maintenance, the mechanic demonstrated to me: you need to empty all items from the trunk, lift the bottom cover plate, and for some models, there's an additional waterproof film underneath that must be carefully removed to reveal the metal base of the spare tire compartment. These four diagonally positioned holes are a crucial design to prevent water leakage. If they get blocked, rainwater can accumulate in the spare tire well during rainy days, and in severe cases, it may seep into the carpet layer. I once encountered drainage issues when my car was parked under an old camphor tree. Later, I applied some grease around the holes to prevent rust and regularly used a high-pressure air gun to clear the passages. I remember a fellow car owner sharing on the forum last year that the hole near the right taillight is more prone to mud clogging than the one on the left.

I often remind fellow car owners to pay attention to the trunk drainage holes. On the CS35, the drainage holes are all located in the spare tire well, with one in each of the four corners. Clear out the trunk, lift the mat, and remove the spare tire to see the round holes on the floor panel. Routine maintenance is simple: use a vacuum cleaner to remove dust around the area, and use tweezers to pick out any accumulated leaves. During the last heavy rain, I found the spare tire well had water two fingers deep—it turned out the rear left corner hole was clogged. These holes are designed to drain water without letting insects in, which is crucial, but accumulated mud and sand can affect the seal. It's best to apply some silicone sealant below the holes for leakage prevention when you get a new car.
