Is it okay if the car didn't stall after wading through 40 cm of water?

Even if the car didn't stall after wading through 40 cm of water, it can still have an impact on the vehicle. Here is the relevant information: 1. Reason: Cars are not amphibious vehicles. Although they have extensive waterproof designs on the surface, there is still a possibility of water ingress or moisture after wading. It's best to inspect the engine compartment, engine air intake, wheels, brake discs, and other areas for any foreign objects after wading to avoid affecting driving safety. 2. Deep wading: If the wading was relatively deep, a comprehensive inspection of the vehicle is necessary afterward. Check electrical components, the air filter, and the chassis. It may also be necessary to completely replace the engine oil and transmission fluid, as the engine oil pan and transmission have some air holes, making it difficult to know if water has mixed in. If water has entered, it can easily cause deterioration.
Last time I drove my old SUV through standing water, I encountered this exact situation. Forty centimeters is basically the limit for sedan ground clearance. Although I was lucky it didn't stall, there were plenty of hidden troubles. Most engine air intakes are located near the wheels, and water over 30cm deep can backflow into the air filter. A wet filter element might seem fine at first, but it'll crack and leak dust when dried. The exhaust tailpipe bubbling in water leaves rust inside after cooling. The worst issues are the half-shaft oil seals and transmission breather holes - prolonged immersion causes sealing grease to emulsify. My neighbor's car started leaking oil three months later. I suggest you listen for any abnormal humming sounds from the wheels in coming days, which could indicate water in the bearings. Take advantage of clear weather to immediately inspect all rubber components underneath, especially those corrugated dust boots.
