The drain hole of the trunk is located under the spare tire in the trunk, and the spare tire position is the bottommost part of the trunk. Extended content: The drain holes are usually blocked with rubber plugs to prevent rainwater from flowing back into the car through the drain holes. If there is a water leak, the cause of the leak should be identified and resolved at the source. Since the spare tire area in the trunk is a lower part of the vehicle body, water may flow to this position from inside the car body if the vehicle wades through deep water or water seeps in through the gaps of the headlights. Therefore, drain holes are reserved inside the car. However, due to the low usage efficiency of drain holes and the high probability of rainwater flowing back into the car through them, most manufacturers block them with soft plastic. The trunk drain holes are generally designed as one or two, and they can be opened when draining water is needed.

After driving the Sail for so long, I often need to clean the trunk drainage hole. That small hole is hidden under the trunk floorboard. You just need to empty the trunk, lift the rubber mat or spare tire cover, and it's usually located in the left or right corner near the rear wheel arch. I've encountered blockages several times myself—when it rains, water fills up the trunk, and you can immediately tell the water isn't draining properly. Just use a thin wire or chopstick to gently poke through it, but be careful not to apply too much force and damage the edges of the hole. I check it every two or three months, especially after parking under trees, as leaves and dust can quickly clog it. This habit has prevented rust and odd smells in the trunk, and it applies to other cars too. Never overlook this small spot, as accumulated water can corrode the floorboard, leading to costly repairs. Each cleaning takes just a few minutes but ensures your beloved car stays durable for years.

As an average car owner, I've found the location of the Sail's trunk drain hole quite crucial. It's that small opening designed to prevent water accumulation in the trunk, situated beneath the floor panel. By lifting the trunk liner or removing the spare tire cover, you'll typically spot it in the left or right rear corner. I make it a habit to inspect it during car washes, doing a quick debris cleanup. Parking under trees often leads to clogging - after clearing it, pour a bucket of water to test drainage. Smooth flow means all's well. Pro tip: wear gloves to avoid dirtying your clothes. Neglecting regular cleaning may cause rainwater to backflow into the trunk, eventually leading to metal corrosion (with annoying squeaks) and musty odors. Developing this simple maintenance routine will give you much greater peace of mind when driving your Sail.

From a car maintenance perspective, the Sail's trunk drain hole is located in the lower corner beneath the floor panel. Lifting the interior mat reveals it, designed to drain accumulated water and prevent rust. Neglecting to clean it can lead to blockages, causing rainwater accumulation in the trunk which may trigger rust or short circuits in electronic components, increasing safety risks. It's recommended to perform a simple inspection and cleaning every quarter.
