Is the car chassis waterproof?
2 Answers
Car chassis are not waterproof. Below is relevant information about car driving licenses: C1 driver's license: C1 is the highest level in driver's licenses, allowing the operation of small and micro passenger vehicles, light, small, and micro cargo vehicles, as well as small and micro special operation vehicles. Additionally, it permits driving all vehicle types covered by C2, C3, C4, and C5 driver's licenses. C2 driver's license: C2 is the designation for small automatic transmission vehicles, allowing the operation of small and micro automatic transmission passenger vehicles, as well as light and micro automatic transmission cargo vehicles; light and micro special operation vehicles.
During the last maintenance, the technician showed me the undercarriage, and I realized that the original metal parts already had rust-proof treatment with sealing strips at the joints. However, there are actually heat dissipation holes under the engine guard plate, so water can still seep through when driving through deep water. During heavy rain, I'm most afraid of water exceeding half the tire height, as the transmission vent might take in water. Now, after washing the car, I always check if there's any water accumulation sound under the chassis, especially under the rear seats—the lowest point of the undercarriage. Before heading out in the rainy season, I spray a layer of undercoating adhesive (30 yuan per can on Taobao, quite effective) an hour in advance.
