Is It Safe to Drive Through Water Without Stalling?
2 Answers
Driving through water without stalling doesn't mean it's completely safe; it only indicates that the engine might be fine. Cars are not amphibious vehicles. While many components have waterproof designs, there's still a possibility of water ingress or moisture damage. After driving through water, it's best to get out and inspect the engine compartment, engine air intake, wheels, brake discs, exhaust pipe, carbon canister, and other areas for any foreign objects to ensure safety for the next drive. Potential hazards of driving through water: 1. Engine damage: Water entering the engine can cause issues like insufficient power and shaking. Prolonged use may lead to piston rod deformation or even breakage, ultimately damaging the engine. 2. Stalling: A wet or short-circuited high-voltage distribution system can cause stalling. Water entering the exhaust pipe can also lead to stalling.
I've driven through puddles multiple times on rainy days, and even if the engine doesn't stall, it doesn't necessarily mean everything's fine. If the water level exceeds half the wheel height, water can flood into the exhaust pipe or electrical connectors, causing short circuits or corrosion. Once after crossing deep water, my undercarriage rusted severely, the brake discs became slippery, and handling turned sluggish. Afterwards, a thorough undercarriage cleaning and sensor inspection were necessary—otherwise, accumulated hidden dangers could lead to major issues. Avoid high-speed water crossings; driving through slowly and steadily is safer.
