Should the Vehicle Maintain Low Speed After Wading Through Water?
2 Answers
After wading through water, the vehicle should maintain low speed and adopt the method of intermittent light braking repeatedly to generate heat through friction between the brake drum and brake pads, thereby evaporating and draining the water. During driving, if encountering waterlogged roads, as long as the water level reaches two-thirds of the bumper or tire height, continuing to drive through water poses certain risks. Additional Information: 1. While driving, if encountering waterlogged roads where the water level reaches two-thirds of the bumper or tire height, continuing to drive through water is very dangerous. High speed will increase the actual water depth the vehicle passes through, causing rainwater to enter the cabin from the engine compartment or chassis. If observation shows a high water level, it is advisable to detour whenever possible. 2. Besides maintaining low speed when wading through water, try to avoid stopping, shifting gears, releasing the throttle, or accelerating. Instead, pass through steadily at low gear with medium to high throttle, avoiding high speed that could splash large waves or water. 3. Water entering the engine is a very serious issue. Water can enter through the air filter into the intake valve and then into the cylinder block via the intake pipe. In such cases, do not attempt to start the engine again.
After driving for so many years, I often encounter waterlogged sections of the road. After driving through water, it's indeed necessary to maintain a low speed. Why? High-speed driving can cause waves to surge, making it easier for water to rush into the engine's air intake or exhaust system, leading to stalling or even severe damage. Driving at a low speed for a few minutes after passing through water also helps the brake system gradually dry out the accumulated water; otherwise, emergency braking might cause skidding and accidents. I believe safety comes first—don’t rush. Moving steadily and driving slowly for a short distance afterward can save a lot of repair troubles. Additionally, always observe the water depth; if it’s too deep, don’t force your way through to avoid water flooding the cabin and causing more issues. Regular maintenance should include checking the chassis seals—preventive maintenance is crucial.
