What precautions should be taken when driving in deep water?

Precautions for driving in deep water are as follows: 1. Maintain a low speed: Try not to stop, shift gears, release the throttle, or accelerate. Instead, drive at a steady speed with low gear and moderate throttle to pass through smoothly, avoiding splashing large waves or water by driving too fast. 2. Do not restart the engine immediately if it stalls: Take measures to tow the car to a safe location with less water as soon as possible. Water entering the engine is a serious issue; it can pass through the air filter into the intake valve and then into the cylinder via the intake pipe. Do not attempt to restart the engine, as this may cause deformation of critical components like the crankshaft and connecting rod, leading to engine vibration or even breakage of parts. Stalling in water likely means water has entered the engine, and the only solution is to tow the car in neutral to a repair shop for cleaning. 3. Remove moisture from the brake pads promptly: Drive at a low speed while lightly pressing the throttle and gently applying the brakes. If you're not comfortable doing both at once, you can press the brakes multiple times. Ensure the speed is slow and repeat the process several times to generate heat through friction between the brake drum and pads, evaporating and drying out the moisture.
Driving through deep water is truly an art. With over 20 years of driving experience, I always exercise extra caution after rain. First, never force your way through. If the water depth exceeds half the wheel height, don't risk it - the water pressure could flood the car or even stall the engine, with the worst-case scenario being complete engine failure. I always survey the water flow and underwater conditions beforehand to avoid potholes or large rocks blocking the path. When driving through, use first gear and proceed slowly, keeping engine RPM above 2000 to maintain proper exhaust flow and prevent water intake. If you feel the car might stall midway, stay calm and maintain throttle pressure. Should the engine stall, never attempt to restart immediately to avoid major engine damage. After crossing, immediately test your brakes - if wet, gently pump them several times to dry. I also check the dashboard for warning lights since electronic systems are particularly vulnerable to water damage. Finally, inspect the undercarriage and floor mats to ensure no water remains. During routine maintenance, have mechanics check seal integrity for waterproofing - thorough preparation is the key to safety.
