Is it okay to drive through water without turning off the car?
3 Answers
Driving through water without turning off the car is generally fine as long as the water depth does not allow it to seep into the vehicle. Here are detailed explanations about car driving: 1. Overview: Driving a car is one of the essential skills that modern individuals need to master. To acquire driving-a-motor-vehicle skills, one must meet the required age and physical conditions, and undergo training and examinations on road traffic safety laws and regulations, basic knowledge of automobile mechanics, and safe driving practices. 2. Others: The permission to drive a vehicle is granted through the issuance of a driver's license. This indicates that obtaining a driver's license is a formal procedure that must be issued by an authorized agency.
I previously specialized in researching vehicle water wading issues. When the water depth exceeds half of the tire height, it becomes extremely dangerous. The biggest fear when driving through water without stalling is the engine's air intake sucking in water. Once water enters the cylinders, it can block them, causing the piston to bend the connecting rod when forced upward. Repairs for this can cost tens of thousands. Water entering the vent hole of an automatic transmission can also contaminate the fluid, potentially causing gear shift hesitation within days. Submerged electrical connectors may lead to leakage or short circuits, especially dangerous for hybrid vehicles' high-voltage battery packs. After passing through water, it's best to check if the air filter is damp, listen for unusual noises from the chassis, and if the engine oil smells milky, it indicates water contamination. It's recommended to stop the engine immediately and wait for towing assistance. Don't hesitate over the towing fee—it's much more cost-effective than major repairs.
Having worked with cars for years, I've noticed that many people underestimate the dangers of driving through water. Even if the water level only reaches the center of the wheels, it can cause oxidation in the electrical wiring harness under the chassis. The engine air intake is typically located at one-third height behind the grille, making it vulnerable to water ingress from the bow wave created when crossing water. The key is to observe the height of water splashes from vehicles ahead and maintain sufficient distance. The most troublesome components are the differential and bearings - if water enters, the grease emulsifies, potentially causing humming noises within half a month. If water levels suddenly rise during crossing, never reverse, as the backflow wave can instantly submerge the hood. The auto start-stop system must be deactivated in advance to prevent catastrophic engine damage from restarting in water. After water crossing, repeatedly apply light brake pressure to remove the water film from brake discs, as the first brake application might otherwise fail.
