What is the correct way to handle a vehicle after wading through water?

When driving through water, vehicle owners must operate their cars correctly. Improper operation not only prevents the vehicle from safely passing through waterlogged areas but also creates serious potential malfunctions. The correct handling methods are as follows: 1. Slow down or stop to observe: While driving, if you encounter a waterlogged road, you should slow down or stop to observe. Once the water level reaches two-thirds of the bumper or tire height, continuing to drive through the water poses certain risks. High speed increases the actual depth of water the vehicle passes through, causing water to enter the cabin from the engine compartment or chassis. Avoid driving against waves created by large vehicles. If observation reveals a high water level, try to detour instead of forcing your way through. 2. Maintain a steady speed with low gear and moderate throttle: When wading through water, besides keeping a low speed, try not to stop, shift gears, release the throttle, or accelerate. Instead, drive steadily at a low gear with moderate throttle, avoiding high speeds that create large splashes or waves. 3. If the car stalls in water, do not restart it immediately: Instead, take measures to tow the vehicle to a safe location with less water as soon as possible. Water entering the engine is a severe issue, as it can pass through the air filter into the intake valve and then into the cylinder block via the intake pipe. Do not attempt to restart the engine at this point, as it could cause critical components like the crankshaft and connecting rods to deform, leading to engine vibration or even part breakage. Stalling in water likely means the engine has taken in water, and the only solution is to tow the car in neutral to a repair shop for cleaning. 4. After wading through water, promptly remove moisture from the brake pads: This is especially important for vehicles with drum brakes, as failure to do so can result in loss of braking power, leading to severe hazards or accidents. The specific method is to drive at low speed while pressing the throttle and lightly applying the brakes. Those unfamiliar with simultaneous pedal use can press the brakes multiple times, ensuring the speed remains slow. Repeat this process several times to generate friction heat between the brake drum and pads, evaporating the moisture.
After driving through water, my top priority is safety. Once the vehicle has passed through standing water, immediately pull over and turn off the engine. Never attempt to continue driving or restart the engine, as this can cause water to be sucked into the engine, leading to serious damage. I first assess the surroundings to ensure the safety of myself and other passengers, avoiding standing in water to prevent electric shock. Then, I check the exhaust pipe, air intake, and chassis for any water accumulation. If the water level was above the center of the tires, the vehicle is likely already damaged. I call for a tow truck service and let professional mechanics handle it—they can inspect the engine, transmission, and electrical systems for water intrusion to prevent future issues. When driving through waterlogged roads during rainy weather, I slow down and avoid sudden braking, developing good habits to minimize the risk of water exposure. In short: safety first, and seeking professional help promptly is the right approach.
