Black Rain Flooding | Car Flooding Self-Rescue Guide & Tips for Identifying Flooded Used Cars
Hong Kong has recently experienced continuous torrential rains, with the Hong Kong Observatory issuing four black rainstorm warnings in just eight days, the longest of which lasted for over 11 hours, causing severe flooding in many areas. Faced with such severe weather, both owners of gasoline-powered and electric vehicles must know how to cope to ensure their own safety and that of their vehicles. Today, we will guide you through understanding the impact of flooding on cars, explain self-rescue techniques for flooded cars, and teach you how to identify signs of water damage in used cars
1. What to do if your car is flooded while driving? Three self-rescue tips
When encountering heavy rain and flooding, drivers should first remain calm. Here are three emergency tips:
If the depth of the water ahead is uncertain, choose a safe route or higher ground to avoid the flood
Assess water depth and pass safely. If
the water only reaches halfway up the tires, you can drive slowly in a low gear, gently pressing the accelerator throughout the process, and avoid releasing the accelerator to prevent water from flowing back into the exhaust pipe (this is especially important for gasoline-powered vehicles).If the water level exceeds half the tire height, immediately and safely evacuate the vehicle from the deep water area.
If the water level rises to near the vehicle door, it is strongly advised not to continue driving.
2. Should you try to restart the vehicle after it has been flooded?
Remember, never try to restart the engine after it has been flooded. Whether the engine stalls while driving through a flooded area or gets submerged while parked, it means that the engine or other important components have been flooded
Vehicles that have been submerged in water are prone to long-term damage because it is difficult to fully disassemble and inspect the electronic components and parts inside. Generally speaking, if the engine is flooded, it can be repaired by using a special cleaner and tools to rinse the engine interior several times. However, if you try to start the engine after it has been flooded, the water may cause the engine oil to mix with the water, thus losing its protective properties and damaging the parts. In severe cases, it may even render the engine unusable
The best course of action is to have the vehicle towed to a repair shop or original equipment manufacturer (OEM) that the owner trusts for a thorough inspection. Currently, Hong Kong's vehicle flood insurance policies also stipulate that owners cannot restart a vehicle after it has been submerged in water
3. Are electric vehicles really not afraid of water immersion?
In traditional cars, water entering the exhaust pipe can cause the engine to stall. While electric vehicles lack traditional engines, they are not immune to water damage. For example, official Tesla tests show that the safe wading depth is less than half the tire height. If the water depth exceeds this range, water may seep into the high-voltage battery system, causing malfunctions or even safety hazards. Therefore, electric vehicle owners must also remain vigilant and avoid driving into deep water
4. Car Purchase Advice: How to Identify a Flood-Damaged Used Car?
When buying a vehicle, you should choose carefully, especially during the rainy season. How can you avoid buying a flood-damaged car?
We suggest paying attention to the following key points:
Unpleasant odors and moldy spots inside the car: a musty smell after dampness, mold on carpets or under seats
Electronic equipment malfunction: The central control system, window lifts, lights, etc., are not working properly
Body rust: Abnormal rust on the chassis and door seams, etc
Check the vehicle's maintenance records: see if there has been any repair work involving prolonged immersion in water
If you are unsure, it is best to have a professional technician conduct a comprehensive inspection to ensure that you are buying a safe and reliable used car
