Does the Classic Sylphy have drainage holes under the chassis?

No. Here is more information about drainage holes: 1. Below the fuel tank cover: Since the fuel tank's sealing is not as tight as imagined, fuel may spill during the insertion or removal of the fuel nozzle. Therefore, this can also serve as an oil drainage hole. Additionally, the drainage hole here prevents water accumulation, avoiding the fuel tank cover from freezing shut in winter. 2. Trunk drainage hole: Generally located near the spare tire, it is only needed in extreme situations like vehicle submersion. Some manufacturers may seal the trunk drainage hole before delivery, which can be punctured when needed. 3. Air conditioning drainage hole: Usually located below or in front of the passenger seat. Turn on the air conditioning and observe where water drips outside the car to locate the air conditioning drainage hole. If unexplained water accumulation is found on the passenger floor, it may be due to a blocked drainage hole causing backflow, which can be cleared with thin wire.
I found that the classic Sylphy does have drainage holes designed in the chassis, mainly located under the door sills and along the edges of the trunk. These holes are used to drain rainwater or car wash water, preventing water accumulation that could corrode the chassis or seep into the car. My car used to have slightly wet carpets after rain, and upon inspection, I discovered that the drainage holes under the door sills were clogged with leaves. Using a small wire or air gun to clear them solves the problem, and it's a good idea to clean them regularly during car washes. If neglected for a long time, the metal parts of the chassis can easily rust, and the wiring harnesses may become damp and short-circuit. Especially in older Sylphy models, where the door seals have aged, clogged drainage holes are more common. It's recommended to have the mechanic blow out these hidden areas during each maintenance session to extend the chassis's lifespan. When washing the car yourself, you can also use a water gun to flush these holes, which is both convenient and safe.
From a structural design perspective, the classic Sylphy has drainage holes installed around the chassis. These are mainly located at the bottom of the sill beams and the inner side of the wheel arches, with holes roughly the size of mung beans. These holes serve a critical function—water inevitably seeps into the body welding seams, and if not drained promptly, accumulated water can accelerate rust penetration in the chassis metal. I once saw a ten-year-old Sylphy with a rotten and perforated chassis, all because the drainage holes were clogged with sludge. Cleaning them is actually quite simple: when parked, lift the rubber strip under the door to locate the small holes. Use a toothpick to clear any debris, then pour water to test the drainage speed. In humid southern regions, extra attention is needed—it's best to perform this maintenance before the rainy season. If you're modifying the chassis underbody panels, make sure to avoid blocking the original drainage points, or the risks could be even greater.
